Thawing ice makes the Alps grow

SCIENCEDAILY - 19 November 2016

The Alps are steadily "growing" by about one to two millimeters per year. Likewise, the formerly glaciated subcontinents of North America and Scandinavia are also undergoing constant upward movement. This is due to the fact that at the end of the Last Glacial Maximum (LGM), the glaciers melted and with this the former heavy pressure on the Earth's surface diminished. Now, an international team of researchers has been able to show that the loss of the LGM ice cap still accounts for 90 percent of today's uplifting of the Alps.

Better models to forecast effects of environmental change on food webs

SCIENCEDAILY - 04 October 2016

Ppredator-feeding behavior, global warming, and nutrient enrichment affect the basic building blocks of food webs, says a new dissertation. Just a small increase in temperature or in the availability of a limited nutrient can theoretically push the populations of predators and their prey from stable coexistence at approximately constant densities to wild oscillations, or even to predator extinction. But how and when this happens is still debated by ecologists.

Environmental stress enhances the effects of pollutants

Threats to habitat connectivity as sea waters inundate coastal areas

SCIENCEDAILY - 28 June 2016

By the year 2100, sea levels might rise as much as 2.5 meters above their current levels, which would seriously threaten coastal cities and other low-lying areas. In turn, this would force animals to migrate farther inland in search of higher ground. But accelerated urbanization, such as the rapidly expanding Piedmont area that stretches from Atlanta to eastern North Carolina, could cut off their escape routes and create climate-induced extinctions.

Ocean pollution: Focusing on fragmentation of plastic waste

SCIENCEDAILY - 31 May 2016

First discovered by sailors, the masses of plastic debris floating at the center of vast ocean vortices called gyres are today under close scrutiny by scientists. To better understand the fragmentation of microplastics under the effect of light and abrasion by waves, researchers combined physico-chemical analyses with statistical modeling. They were thus able to show that pieces of plastic debris behave in very different ways according to their size. The bigger pieces appear to float flat at the surface of the water, with one face preferentially exposed to sunlight. However, the researchers observed fewer small-sized debris (around 1 mg) than predicted by the mathematical model.

When did the Andes mountains form?

SCIENCEDAILY - 22 November 2015

The Andes were formed by tectonic activity whereby Earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction zone setting is unusual, which adds to the importance of trying to figure out when and how it happened. However, the timing of when the Andean mountain chain uplift occurred has been a topic of some controversy over the past ten years. Now, new research shows that the Andes have been a mountain chain for much longer than previously thought.

Is old rock really 'as solid as a rock'? Deformed craton under North America

SCIENCEDAILY - 13 September 2015

In the course of billions of years continents break up, drift apart, and are pushed back together again. The cores of continents are, however, geologically extremely stable and have survived up to 3.8 billions of years. These cores that are called cratons are the oldest known geological features of our planet. It was assumed that the cratons are stable because of their especially solid structure due to relatively low temperatures compared to the surrounding mantle. Now researchers have discovered that the craton below the North American continent is extremely deformed: its root is shifted relative to the center of the craton by 850 kilometers towards the west-southwest.

Researchers explain mystery of India’s rapid move toward Eurasia 80 million years ago

THE ARCHEOLOGY NEWS - 07 May 2015

In the history of continental drift, India has been a mysterious record-holder. More than 140 million years ago, India was part of an immense supercontinent called Gondwana, which covered much of the Southern Hemisphere. Around 120 million years ago, what is now India broke off and started slowly migrating north, at about 5 centimeters per year. Then, about 80 million years ago, the continent suddenly sped up, racing north at about 15 centimeters per year -- about twice as fast as the fastest modern tectonic drift. The continent collided with Eurasia about 50 million years ago, giving rise to the Himalayas.

Human hunting weapons may not have caused the demise of the Neanderthals

SCIENCEDAILY - 06 May 2015

The demise of Neanderthals may have nothing to do with innovative hunting weapons carried by humans from west Asia, according to a new study. The researchers say their findings mean that we may need to rethink the reasons humans survived Neanderthals - and that we may not have behaved as differently as we thought. The researchers looked at innovative stone weapons used by humans about 42,000-34,000 years ago. Traditionally, anthropologists believed that innovation in weapons enabled humans to spread out of Africa to Europe. However, the new study suggests that the innovation was not a driving force for humans to migrate into Europe as previously thought - they were no better equipped than the Neanderthals.

Since life originated on Earth between 3.8 and 3.9 Ga ago, microorganisms have significantly shaped and influenced the chemistry of Earth's surface and subsurface environments. Reconstructing the evolution of early microbial life depends mainly on finding organic and mineral remnants of microbial activity preserved in the rock record. Even when microfossils are found, there are often controversies about their biological origin, since parameters that lead to a good preservation of microfossils are not well constrained.

Plants survive better through mass extinctions than animals

Rapid end of the Green Sahara 8000 years ago

THE ARCHEOLOGY NEWS - 16 February 2015

9,000 years ago most of the Sahara was not the ultra-arid desert as we know it today. Due to higher precipitation it was covered by large lakes and savannah that were populated by herds of wild game. Scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Royal Netherlands Institute for Sea Research (NIOZ) now have discovered that vegetation at the end of the Green Sahara disappeared much faster than previously assumed. This probably forced the Neolithic populations to start farming. The study has been published in the international open-access journal PLOS ONE.

Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet

THE ARCHEOLOGY NEWS - 11 February 2015

Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly regular cycles, ranging from two weeks to 100,000 years -- and, that they erupt almost exclusively during the first six months of each year. The pulses -- apparently tied to short- and long-term changes in earth's orbit, and to sea levels--may help trigger natural climate swings. Scientists have already speculated that volcanic cycles on land emitting large amounts of carbon dioxide might influence climate; but up to now there was no evidence from submarine volcanoes. The findings suggest that models of earth's natural climate dynamics, and by extension human-influenced climate change, may have to be adjusted. The study appears this week in the journal Geophysical Research Letters.

New research shows our seas are in trouble

Ancient deformation of the lithosphere revealed in Eastern China

PHYS.ORG - 31 January 2015

Seismic investigations from the Qinling-Dabie-Sulu orogenic belt in eastern China suggest that this region was affected by extreme mantle perturbation and crust-mantle interaction during the Mesozoic era. The Qinling-Dabie-Sulu orogenic belt formed through the collision between the North and South China blocks, which produced large-scale destruction of the cratonic lithosphere, accompanied by widespread magmatism and metallogeny.

Fossils survive volcanic eruption to tell us about the origin of the Canary Islands

Why is Greenland covered in ice?

THE ARCHEOLOGY NEWS - 12 January 2015

The ice on Greenland could only form due to processes in the deep Earth interior. Large-scale glaciations in the Arctic only began about 2.7 million years ago; before that, the northern hemisphere was largely free of ice for more than 500 million years. Scientists at the German Research Centre for Geosciences GFZ, Utrecht University, the Geological Survey of Denmark and Greenland (GEUS) and the University of Oslo could now explain why the conditions for the glaciation of Greenland only developed so recently on a geological time scale.

What the 'fecal prints' of microbes can tell us about Earth's evolution

THE ARCHEOLOGY NEWS - 29 December 2014

The distinctive "fecal prints" of microbes potentially provide a record of how Earth and life have co-evolved over the past 3.5 billion years as the planet's temperature, oxygen levels, and greenhouse gases have changed. But, despite more than 60 years of study, it has proved difficult, until now, to "read" much of the information contained in this record. Research from McGill University and Israel's Weizmann Institute of Science, recently published in the Proceedings of the National Academy of Sciences (PNAS), sheds light on the mysterious digestive processes of microbes, opening the way towards a better understanding of how life and the planet have changed over time.

Atmospheric particles can brighten cold clouds as well as warm ones

PHYS.ORG - 05 December 2014

For the first time, modeling research led by Pacific Northwest National Laboratory found that atmospheric particles can brighten cold clouds in the Arctic. Using simulations, they showed that low clouds over the Arctic may be brightened by deliberately injecting small particles known as aerosols. It's already well known that injecting aerosols into low clouds over the warm ocean can, in some circumstances, reduce the amount of sunlight that reaches the surface. The concept, untested over the Arctic until now, is called marine cloud brightening, and it can also happen when ships send exhaust into the atmosphere.

Mass extinction led to many new species of bony fish

PHYS.ORG - 01 December 2014

Today, ray-finned fish, which belong to the bony fish, are by far the most biodiverse fish group in both salt- and freshwater. Their spectacular variety of forms ranges from eels, tuna, flounders and angler fish all the way to seahorses. With around 1,100 species, the second most biodiversegroup is the cartilaginous fish, which are almost exclusively marine and include sharks, rays and chimaeras. Exactly why bony fish managed to prevail in different habitats is the subject of debate: Do they have a better body plan, which is suited to more ecological niches than that of the cartilaginous fish? Or are other factors involved in their successful distribution?

The "Potsdam gravity potato" shows variations in Earth's gravity

PHYS.ORG - 01 December 2014

People tend to think of gravity here on Earth as a uniform and consistent thing. Stand anywhere on the globe, at any time of year, and you'll feel the same downward pull of a single G. But in fact, Earth's gravitational field is subject to variations that occur over time. This is due to a combination of factors, such as the uneven distributions of mass in the oceans, continents, and deep interior, as well as climate-related variables like the water balance of continents, and the melting or growing of glaciers.

Massive debris pile reveals risk of huge tsunamis in Hawaii

PHYS.ORG - 21 October 2014

A mass of marine debris discovered in a giant sinkhole in the Hawaiian islands provides evidence that at least one mammoth tsunami, larger than any in Hawaii's recorded history, has struck the islands, and that a similar disaster could happen again, new research finds. Scientists are reporting that a wall of water up to nine meters (30 feet) high surged onto Hawaiian shores about 500 years ago. A 9.0-magnitude earthquake off the coast of the Aleutian Islands triggered the mighty wave, which left behind up to nine shipping containers worth of ocean sediment in a sinkhole on the island of Kauai.

Brazil's rainforests are releasing more carbon dioxide than previously thought

PHYS.ORG - 07 October 2014

Because of the deforestation of tropical rainforests in Brazil, significantly more carbon has been lost than was previously assumed. As scientists of the Hemholtz Centre for Environmental Research (UFZ) write in the scientific journal Nature Communications, the effect of the degradation has been underestimated in fragmented forest areas, since it was hitherto not possible to calculate the loss of the biomass at the forest edges and the higher emission of carbon dioxide. The UFZ scientists have now closed this knowledge gap. According to their calculations, the forest fragmentation results in up to a fifth more carbon dioxide being emitted by the vegetation.

Geologists are explore the hidden world beneath our feet. Examining the effects of human drilling shows how humans have left their mark on Earth both above the surface and deep below in the subterranean network of human-made tunnels in ways that will have a long-standing impact in the future.

Scientists caution against exploitation of deep ocean

Oregon State University - 30 July 2014

The world's oceans are vast and deep, yet rapidly advancing technology and the quest for extracting resources from previously unreachable depths is beginning to put the deep seas on the cusp of peril, an international team of scientists has warned.

Conservation scientists asking wrong questions on climate change impacts on wildlife

Wildlife Conservation Society - 30 July 2014

Scientists studying the potential effects of climate change on the world's animal and plant species are focusing on the wrong factors, according to a new article. The authors claim that most of the conservation science is missing the point when it comes to climate change.

Worldwide water shortage by 2040

Aarhus University - 29 July 2014

Water is used around the world for the production of electricity, but new research results show that there will not be enough water in the world to meet demand by 2040 if the energy and power situation does not improve before then.

Europe's habitat and wildlife is vulnerable to climate change

University of Southampton - 28 July 2014

New research has identified areas of the Earth that are high priorities for conservation in the face of climate change. Europe is particularly vulnerable, as it has the lowest fraction of its land area, only four per cent, of any continent in ‘refugia’ – areas of biological diversity that support many species where natural environmental conditions remain relatively constant during times of great environmental change.

Global warming amplifier: Rising water vapor in upper troposphere to intensify climate change

University of Miami Rosenstiel School of Marine & Atmospheric Science - 28 July 2014

A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere -- a key amplifier of global warming -- will intensify climate change impacts over the next decades. The new study is the first to show that increased water vapor concentrations in the atmosphere are a direct result of human activities.

Climate change and air pollution will combine to curb food supplies

Massachusetts Institute of Technology - 27 July 2014

Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution -- specifically ozone pollution, which is known to damage crops. A new study shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security.

Synchronization of North Atlantic, North Pacific preceded abrupt warming, end of ice age

Oregon State University - 24 July 2014

Scientists have long been concerned that global warming may push Earth's climate system across a 'tipping point,' where rapid melting of ice and further warming may become irreversible -- a hotly debated scenario with an unclear picture of what this point of no return may look like. A new study suggests that combined warming of the North Atlantic and Pacific Oceans thousands of years ago may have provided the tipping point for abrupt warming and rapid melting of the northern ice sheets.

No returning to Eden: Researchers explore how to restore species in a changing world

University of Otago - 24 July 2014

Reversing the increasing rate of global biodiversity losses may not be possible without embracing intensive, and sometimes controversial, forms of threatened species management, according to zoologists.

Biologist warn of early stages of Earth's sixth mass extinction event

Stanford University - 24 July 2014

The planet's current biodiversity, the product of 3.5 billion years of evolutionary trial and error, is the highest in the history of life. But it may be reaching a tipping point. Scientists caution that the loss and decline of animals is contributing to what appears to be the early days of the planet's sixth mass biological extinction event. Since 1500, more than 320 terrestrial vertebrates have become extinct. Populations of the remaining species show a 25 percent average decline in abundance. The situation is similarly dire for invertebrate animal life.

Climate change: Soil respiration releases carbon

Carnegie Institution - 23 July 2014

The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. Short-term warming studies have documented that rising temperatures increase the rate of soil respiration. As a result, scientists have worried that global warming would accelerate the decomposition of carbon in the soil, releasing more carbon dioxide into the atmosphere and accelerating global warming.

Calcification in changing oceans

The Marine Biological Laboratory - 23 July 2014

What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers -- organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection.

Global warming 'pause' since 1998 reflects natural fluctuation

McGill University - 21 July 2014

Statistical analysis of average global temperatures between 1998 and 2013 shows that the slowdown in global warming during this period is consistent with natural variations in temperature, according to research. The study concludes that a natural cooling fluctuation during this period largely masked the warming effects of a continued increase in human-made emissions of carbon dioxide and other greenhouse gases.

Rainwater discovered at new depths, with high pressure and temperatures over 300 degrees Celsius

University of Southampton - 15 July 2014

Researchers have found that rainwater can penetrate below the Earth’s fractured upper crust, which could have major implications for our understanding of earthquakes and the generation of valuable mineral deposits. It had been thought that surface water could not penetrate the ductile crust - where temperatures of more than 300°C and high pressures cause rocks to flex and flow rather than fracture - but researchers have now found fluids derived from rainwater at these levels. Fluids in the Earth’s crust can weaken rocks and may help to initiate earthquakes along locked fault lines.

Happy Feet III: Adélie penguin population actually on the rise

Stony Brook University - 09 July 2014

The first global census of the Adélie penguin, long considered a key indicator species to monitor and understand the effects of climate change and fishing in the Southern Ocean, has revealed its population (3.79 million breeding pairs) to be 53 percent larger than previously estimated. By using high-resolution satellite imagery, researchers have applied a new method that permits regular monitoring of Adélie penguins across their entire breeding range, and by extension the health of the Southern Ocean ecosystem.

Climate change: Tropical species are most vulnerable to rising temperatures

Senckenberg Research Institute and Natural History Museum - 09 July 2014

Tropical species will be most at risk from rising temperatures as the discrepancy between physiological thermal limits and projected temperatures is highest in tropical regions, research shows. In contrast, a large part of mammal and bird species in temperate zones will find ambient temperatures in 2080 within their tolerance ranges. However, indirect effects of rising temperatures may counteract opportunities given by species’ physiological tolerances in temperate zones, researchers say.

Antarctic climate and food web strongly linked

Virginia Institute of Marine Science - 07 July 2014

A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples up the food chain, with impacts on everything from single-celled algae to penguins.

All the world's oceans have plastic debris on their surface

Spanish National Research Council (CSIC) - 30 June 2014

The Malaspina Expedition, led by the Spanish National Research Council, has demonstrated that there are five large accumulations of plastic debris in the open ocean that match with the five major twists of oceanic surface water circulation. In addition to the known accumulation of plastic waste in the North Pacific, there are similar accumulations in the central North Atlantic, the South Pacific, the South Atlantic and the Indian Ocean.

New study quantifies the effects of climate change in Europe

European Commission Joint Research Centre - 25 June 2014

If no further action is taken and global temperature increases by 3.5°C, climate damages in the EU could amount to at least €190 billion, a net welfare loss of 1.8 percent of its current GDP. Several weather-related extremes could roughly double their average frequency. As a consequence, heat-related deaths could reach about 200,000.

World’s protected areas not protecting biodiversity, but there is room for hope

Wildlife Conservation Society - 24 June 2014

Scientists have warned that the world’s protected areas are not safeguarding most of the world’s imperiled biodiversity, and clear changes need to be made on how nations undertake future land protection if wildlife is going to be saved. These findings come at a time when countries are working toward what could become the biggest expansion of protected areas in history.

Regional weather extremes linked to atmospheric variations

University of Exeter - 22 June 2014

Variations in high-altitude wind patterns expose particular parts of Europe, Asia and the US to different extreme weather conditions, a new study has shown. Changes to air flow patterns around the Northern Hemisphere are a major influence on prolonged bouts of unseasonal weather -- whether it be hot, cold, wet or dry.

Chemical pollution of European waters is worse than anticipated

Helmholtz Centre For Environmental Research - UFZ - 17 June 2014

Substantial improvements in freshwater quality by 2015 have been a declared objective of the EU member states, manifesting itself by the requirements of the Water Framework Directive. A recent study shows that this target is unlikely to be met due to the high levels of toxicants in the water bodies. One of the reasons: current measures for the improvement of water quality do not account for the effects of toxic chemicals. The study demonstrates for the first time on a pan-European scale that the ecological risks posed by toxic chemicals are considerably greater than has generally been assumed.

Shipping needs radical rethink warn climate experts

Manchester University - 17 June 2014

Avoiding dangerous levels of climate change requires a radical rethink of the shipping system, according to a new report. If global shipping is to make its fair contribution to avoiding the 2°C of warming associated with dangerous climate change, CO2 emissions need to be cut within the next decade and fall by at least 80% by 2050 compared to 1990 levels, say experts.

Large Landmasses Existed 2.7 Billion Years Ago

University of Cologne - Universität zu Köln - 15 June 2014

Some 71% of Earth's surface is covered by oceans and 29% by land. The question of when large landmasses emerged from the oceans has always been hotly debated by scientists. New investigations by geoscientists of the University of Cologne in cooperation with the University of Bonn and the Jacobs University Bremen have shown that large land masses did indeed exist on Earth 2.7 billion years ago

Warming climates intensify greenhouse gas given out by oceans

ScienceDaily - 15 June 2014

Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans,

No limits to human effects on clouds

ScienceDaily - 15 June 2014

Atmospheric particles affect cloud formation in real time, researchers suggest. Clouds need tiny particles called aerosols that rise in the atmosphere, in order to form.

Scientists discover link between climate change and ocean currents over 6 million years

ScienceDaily - 15 June 2014

Scientists have discovered a relationship between climate change and ocean currents over the past six million years after analyzing an area of the Atlantic near the Strait of Gibraltar, according to new research.

Australia's deadly eruptions were reason for the first mass extinction

Curtin University - 30 May 2014

Ancient volcanic eruptions in Australia 510 million years ago significantly affected the climate, causing the first known mass extinction in the history of complex life. Scientists used radioactive dating techniques to precisely measure the age of the eruptions of the Kalkarindji volcanic province.

Earth's lower mantle may be significantly different than previously thought

Carnegie Institution - 22 May 2014

Breaking research news reveals that the composition of the Earth's lower mantle may be significantly different than previously thought. The lower mantle comprises 55 percent of the planet by volume and extends from 670 and 2900 kilometers in depth, as defined by the so-called transition zone (top) and the core-mantle boundary (below). Pressures in the lower mantle start at 237,000 times atmospheric pressure (24 gigapascals) and reach 1.3 million times atmospheric pressure (136 gigapascals) at the core-mantle boundary.

Experts call for urgent defense of deep ocean

University of Southampton - 15 May 2014

An oceanographer is working with experts from around the globe to warn against lasting damage to the deep ocean, caused by fishing, oil and gas development, industrial-scale mining, waste disposal and land-based pollution. The world's deep ocean spans more than half the planet and holds vast quantities of untapped energy resources, precious metals and minerals. But as advancements in technology enable greater access to these treasures of the deep, experts are urging caution, highlighting the potentially irreversible damage that extracting such materials can cause.

Phytoplankton and zooplankton biomass are expected to decrease by 6% and 11% respectively by the end of century due to climate change

Basque Research - 07 May 2014

It is estimated that ocean temperature warming will cause phytoplankton and zooplankton biomass to decrease by 6% and 11% respectively by the end of the century. A lower amount of these two main elements in the marine food web could reduce fish biomass in certain regions.

Global warming not uniform around the globe: Some areas were recently cooling

Florida State University - 04 May 2014

New research shows the first detailed look at global land surface warming trends over the last 100 years, illustrating precisely when and where different areas of the world started to warm up or cool down.

Climate change study reveals unappreciated impacts on biodiversity

University of Copenhagen - 01 May 2014

The tropics ill be highly affected by local changes in temperature and precipitation, leading to novel climates with no current analogues in the planet. These results expose the complexities of climate change effects on biodiversity and the challenges in predicting and preserving natural ecosystems in a changing Earth.

European seafloor survey reveals depth of marine litter problem

University of Plymouth - 30 April 2014

A major new survey of the seafloor has found that even in the deepest ocean depths you can find bottles, plastic bags, fishing nets and other types of human litter. The litter was found throughout the Mediterranean, and all the way from the continental shelf of Europe to the Mid-Atlantic Ridge 2,000 kilometers from land. Litter is a problem in the marine environment as it can be mistaken for food and eaten by some animals or can entangle coral and fish -- a process known as "ghost fishing."

Recommendations on climate change mitigation

Kansas State University Research and Extension - 17 April 2014

Changing agricultural practices and ending food waste around the world are among recommendations made by scientists charged with looking at ways to mitigate global climate change. "Agriculture globally contributes about 10 to 12 percent to greenhouse gas emissions," the author said. "If you add in forestry it moves it up to around 25 percent. Agriculture is significant but not the major contributor and has declined slightly, percentage-wise, since the last report in 2007, not so much because agriculture has changed that much but because the energy sector is contributing more."

Researchers rethink 'natural' habitat for wildlife

Stanford University - 17 April 2014

Protecting wildlife while feeding a world population predicted to reach nine billion by 2050 will require a holistic approach to conservation that considers human-altered landscapes such as farmland, according to researchers. A new study finds that a long-accepted theory used to estimate extinction rates, predict ecological risk and make conservation policy recommendations is overly pessimistic. The researchers point to an alternative framework that promises a more effective way of accounting for human-altered landscapes and assessing ecological risks.

European climate at the 2 degrees Celsius global warming threshold

Uni Research - 15 April 2014

A global warming of 2 degrees Celsius relative to pre-industrial climate has been considered as a threshold which society should endeavor to remain below, in order to limit the dangerous effects of anthropogenic climate change.

Result of slow degradation on environmental pollutants

ETH Zurich - 14 April 2014

Why do environmental pollutants accumulate in the cold polar regions? This may not only be due to the fact that many substances are less volatile at low temperatures, as has been long suspected, but also to their extremely slow natural degradation. Although persistent environmental pollutants have been and continue to be released worldwide, the Arctic and Antarctic regions are significantly more contaminated than elsewhere. The marine animals living there have some of the highest levels of persistent organic pollutant (POP) contamination of any creatures.

Climate models underestimate costs to future generations

University of Gothenburg - 08 April 2014

Future generations will have to pay more for today's carbon emissions than what governments across the world currently understand. The climate models used by policymakers around the world to estimate the economic and social costs of CO2 emissions have to be improved according to experts.

Permafrost thawing could accelerate global warming

Florida State University - 07 April 2014

Researchers have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends. Permafrost is soil that is frozen year round and is typically located in polar regions. As the world has gotten slightly warmer, that permafrost is thawing and decomposing, which is producing increased amounts of methane.

'Like a giant elevator to the stratosphere:' Newly discovered atmospheric layer may impact Earth's climate

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research - 04 April 2014

An international team of researchers has discovered a previously unknown atmospheric phenomenon over the tropical West Pacific. Like in a giant elevator to the stratosphere, many chemical compounds emitted at the ground pass unfiltered through the so-called 'detergent layer' of the atmosphere, known as the 'OH shield.' The newly discovered phenomenon over the South Seas boosts ozone depletion in the polar regions and could have a significant influence on the future climate of the Earth.

Scientists unmask the climate uncertainty monster

University of Bristol - 04 April 2014

Increasing uncertainty in the climate system compels a greater urgency for climate change mitigation, according to new research. Scientists have shown that as uncertainty in the temperature increase expected with a doubling of carbon dioxide from pre-industrial levels rises, so do the economic damages of increased climate change. Greater uncertainty also increases the likelihood of exceeding 'safe' temperature limits and the probability of failing to reach mitigation targets. The authors highlight this with the case of future sea level, as larger uncertainty in sea level rise requires greater precautionary action to manage flood risk.

Warming climate may spread drying to a third of earth: Heat, not just rainfall, plays into new projections

The Earth Institute at Columbia University - 31 March 2014

A new study estimates that 12 percent of land will be subject to drought by 2100 through rainfall changes alone; but the drying will spread to 30 percent of land if higher evaporation rates are considered. An increase in evaporative drying means that even regions expected to get more rain, including important wheat, corn and rice belts in the western United States and southeastern China, will be at risk of drought.

Ancient whodunit may be solved: Methane-producing microbes did it!

Massachusetts Institute of Technology - 31 March 2014

Methane-producing microbes may be responsible for the largest mass extinction in Earth's history. Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out -- by far the largest of this planet's five known mass extinctions. It turns out that Methanosarcina had acquired a particularly fast means of making methane, and the team's detailed mapping of the organism's history now shows that this transfer happened at about the time of the end-Permian extinction.

Amphibians and dinosaurs were the new large predators after the mass extinction

University of Zurich - 20 March 2014

Some 252 million years ago, the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear. Palaeontologists now show that the food nets during the Early Triassic did not recover in stages. Large predators like, for instance, crocodile-like amphibians and later the precursors of the known plesiosaurs and ichthyosaurs went in search of prey in the oceans soon after the end of the mass extinction.

Ancient food webs developed modern structure soon after mass extinction

Santa Fe Institute - 19 March 2014

Analysis of a highly detailed picture of feeding relationships among 700 species from a 48 million year old ecosystem provides the most compelling evidence to date that ancient food webs were organized much like modern food webs. The results are significant because they show that the Messel ecosystem developed a modern ecological structure, along with a modern biota, in a relatively brief 18 million year period following Earth's most recent die-off, the end-Cretaceous mass extinction, which disrupted ecosystem dynamics on a massive scale and served as a species diversity bottleneck.

Africa's air pollution underestimated in climate change models

CNRS - 13 March 2014

Human activity in Africa significantly contributes to air pollution. However, no detailed data regarding country-by-country pollutant emissions in the continent was available until now. To remedy this scientists mapped these emissions in Africa for 2005, before estimating them for 2030, using three scenarios. The researchers showed that the climate change models used by the IPCC underestimate Africa's emissions, which could account for 20-55% of global anthropogenic emissions of gaseous and particulate pollutants by 2030.

Understanding how mountains and rivers make life possible

Stanford University - 13 March 2014

Scientists have devised a pair of math equations that better describe how the topography and rock composition of a landscape affects the process by which carbon dioxide is transferred to oceans and eventually buried in Earth's interior. Scientists have long suspected that the so-called the geologic carbon cycle is responsible for Earth's clement and life-friendly conditions because it helps regulate atmospheric concentrations of CO2, a greenhouse gas that acts to trap the sun's heat. This cycle is also thought to have played an important role in slowly thawing the planet during those rare times in the past when temperatures dipped so low that the globe was plunged into a "snowball-Earth" scenario and glaciers blanketed the equator.

Ocean food web is key in the global carbon cycle

University of California - Santa Barbara - 11 March 2014

Nothing dies of old age in the ocean. Everything gets eaten and all that remains of anything is waste. But that waste is pure gold to an oceanographer. In a study of the ocean's role in the global carbon cycle, oceanographers used those nuggets to their advantage. They incorporated the lifecycle of phytoplankton and zooplankton -- small, often microscopic animals at the bottom of the food chain -- into a novel mechanistic model for assessing the global ocean carbon export.

Long-term warming likely to be significant despite recent slowdown

NASA/Goddard Space Flight Center - 11 March 2014

A new study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. The research hinges on a new and more detailed calculation of the sensitivity of Earth's climate to the factors that cause it to change, such as greenhouse gas emissions. The study found Earth is likely to experience roughly 20 percent more warming than estimates that were largely based on surface temperature observations during the past 150 years.

Alaska the Last Frontier ... not for long

Taylor & Francis - 10 March 2014

Alaska, the last great frontier, is being threatened by many proposals to mine an estimated 5.5 trillion tons of coal. Scientists comment on the struggle to keep Alaska untouched.

Urbanization exposes French cities to greater seismic risk

Seismological Society of America - 07 March 2014

French researchers have looked into data mining to develop a method for extracting information on the vulnerability of cities in regions of moderate risk, creating a proxy for assessing the probable resilience of buildings and infrastructure despite incomplete seismic inventories of buildings. The research exposes significant vulnerability in regions that have experienced an 'explosion of urbanization.'

Santorini tree rings support the traditional dating of the volcanic eruption

Swiss Federal Institute for Forest, Snow and Landscape Research WSL - 06 March 2014

Will the dating of the volcanic eruption of Santorini remain an unsolved mystery? The question whether this natural disaster occurred 3,500 or 3,600 years ago is of great historiographical importance and has indeed at times been the subject of heated discussion among experts. After investigating tree rings, scientists have concluded that the volcano erupted in the 16th century BC, rather than any earlier than that.

Earth's mantle plasticity explained: Missing mechanism for deforming olivine-rich rocks

CNRS - 06 March 2014

The Earth's mantle is a solid layer that undergoes slow, continuous convective motion. But how do these rocks deform, thus making such motion possible, given that minerals such as olivine (the main constituent of the upper mantle) do not exhibit enough defects in their crystal lattice to explain the deformations observed in nature? Scientists have provided an unexpected answer to this question. It involves little known and hitherto neglected crystal defects, known as 'disclinations', which are located at the boundaries between the mineral grains that make up rocks.

Europe may experience higher warming than global average

Institute of Physics - 06 March 2014

The majority of Europe will experience higher warming than the global average if surface temperatures rise to 2 degrees C above pre-industrial levels, according to a new study.

Study suggests non-uniform climate warming globally

University of Oklahoma - 05 March 2014

A recent study of five decades of satellite data, model simulations and in situ observations suggests the impact of seasonal diurnal or daily warming varies between global regions affecting many ecosystem functions and services, such as food production, carbon sequestration and climate regulation. The effects of non-uniform climate warming on terrestrial ecosystems is a key challenge in carbon cycle research and for those making future predictions.

Climate change causes high but predictable extinction risks

Stony Brook University - 26 February 2014

Judging the effects of climate change on extinction may be easier than previously thought, according to a new article. Although widely used assessments of threatened species, such as the IUCN Red List, were not developed with the effects of climate change in mind, a study of 36 amphibian and reptile species endemic to the US has concluded that climate change may not be fundamentally different from other extinction threats in terms of identifying species in danger of extinction.

Microbes on floating ocean plastics: Uncovering the secret world of the 'Plastisphere'

American Geophysical Union - 24 February 2014

Scientists are revealing how microbes living on floating pieces of plastic marine debris affect the ocean ecosystem, and the potential harm they pose to invertebrates, humans and other animals.

Oldest bit of crust firms up idea of cool early Earth

University of Wisconsin-Madison - 23 February 2014

With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus. New research reveals data that confirms that Earth’s crust first formed just 160 million years after the formation of our solar system. It also confirms that the timeframe that the planet was a fiery ball covered in a magma ocean came earlier, and that in order to become habitable, Earth cooled and formed its crust during the first geologic eon of the planet. The research may help scientists to understand how other habitable planets may form.

Chronology of geological events prior to the great extinction 66 million years ago

University of the Basque Country - 14 February 2014

New research focusing on the last 3 million years of the Cretaceous period, managed to detail exactly the chronology of the climatic, magnetic and biological events prior to the great extinction of 66 million years ago (Ma.), which includes the disappearance of almost all dinosaurs (except birds). Scientists analyzed gravitational interactions between the Earth, the Moon, the Sun and the planets of the solar system (principally Jupiter) in their work.

Arctic biodiversity under serious threat from climate change

Aarhus University - 14 February 2014

Climate change caused by human activities is by far the worst threat to biodiversity in the Arctic. Some of these changes are already visible. Unique and irreplaceable Arctic wildlife and landscapes are crucially at risk due to global warming caused by human activities according to a new report prepared by 253 scientists from 15 countries.

New maps reveal locations of species at risk as climate changes

CSIRO Australia - 10 February 2014

An international team of scientists has produced global maps showing how fast and in which direction local climates have shifted.

Fish biomass in the ocean may be 10 times higher than estimated: Stock of mesopelagic fish changes from 1,000 to 10,000 million tons

Spanish National Research Council (CSIC) - 07 February 2014

With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean. However, scientists have found that their abundance could be at least 10 times higher. The results are based on the acoustic observations conducted during the circumnavigation of the Malaspina Expedition.

Changing climate: How dust changed the face of Earth

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research - 23 January 2014

In spring 2010, the research icebreaker Polarstern returned from the South Pacific with a scientific treasure -- ocean sediments from a previously almost unexplored part of the South Polar Sea. What looks like an inconspicuous sample of mud to a layman is, to geological history researchers, a valuable archive from which they can reconstruct the climatic history of the polar areas over many years of analysis. This, in turn, is of fundamental importance for understanding global climatic development.

Air pollution from Asia affecting world's weather

Texas A&M University - 21 January 2014

Extreme air pollution in Asia is affecting the world’s weather and climate patterns, according to a new study. Using climate models and data collected about aerosols and meteorology over the past 30 years, researchers found that air pollution over Asia -- much of it coming from China -- is impacting global air circulations.

Fishing; More Protection for Big Ones

Forschungsverbund Berlin e.V. (FVB) - 02 January 2014

Many popular measures to combat overfishing help conserve mostly small juvenile fish. The results from a set of international studies may now revolutionize fishing regulations.

Major Reductions in Seafloor Marine Life from Climate Change by 2100

National Oceanography Centre - 31 December 2013

A new study quantifies for the first time future losses in deep-sea marine life, using advanced climate models. Results show that even the most remote deep-sea ecosystems are not safe from the impacts of climate change.

Solution to Cloud Riddle Reveals Hotter Future: Global Temperatures to Rise at Least 4 Degrees C by 2100

University of New South Wales - 31 December 2013

Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature. Scientists found global climate is more sensitive to carbon dioxide than most previous estimates.

Earth's Crust Was Unstable in Archean Eon; Dripped Down Into Mantle

Universität Mainz - 30 December 2013

Earth's mantle temperatures during the Archean eon, which commenced some 4 billion years ago, were significantly higher than they are today. According to recent model calculations, the Archean crust that formed under these conditions was so dense that large portions of it were recycled back into the mantle. This is the conclusion reached by Dr. Tim Johnson who is currently studying the evolution of Earth's crust as a member of the research team led by Professor Richard White of the Institute of Geosciences at Johannes Gutenberg University Mainz (JGU).

Deepwater Horizon Study Shows Possible Oil Impact On Dolphins

NOAA Headquarters - 19 December 2013

Bottlenose dolphins in Louisiana's Barataria Bay have lung damage and adrenal hormone abnormalities not previously seen in other dolphin populations, according to a new peer-reviewed study published Dec. 18, 2013 in the journal Environmental Science & Technology.

Carbon Capture Technology Could Be Vital for Climate Targets

International Institute for Applied Systems Analysis - 11 December 2013

The future availability of carbon capture and storage (CCS) will be pivotal in reaching ambitious climate targets, according to a new comprehensive study of future energy technologies from IIASA, the Potsdam Institute for Climate Change, the Stanford Energy Modeling Forum, and researchers worldwide.

Alpine Glacier, Unchanged for Thousands of Years, Now Melting: New Ice Cores Suggest Alps Have Been Strongly Warming Since 1980s

Ohio State University - 11 December 2013

Less than 20 miles from the site where melting ice exposed the 5,000-year-old body of Ötzi the Iceman, scientists have discovered new and compelling evidence that the Italian Alps are warming at an unprecedented rate.

New Results from Inside the Ozone Hole

NASA/Goddard Space Flight Center - 11 December 2013

NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole.

Earth’s Sensitivity to Climate Change Could Be 'Double' Previous Estimates, Say Geologists

Geological Society of London, The - 10 December 2013

The sensitivity of Earth's climate to CO2 could be double what has been previously estimated, according to a statement issued by the Geological Society of London.

Vast Freshwater Reserves Found Beneath the Oceans

Flinders University - 08 December 2013

Scientists have discovered huge reserves of freshwater beneath the oceans kilometres out to sea, providing new opportunities to stave off a looming global water crisis.

More Extreme Weather Events Likely: Climate Projections of Unparalleled Accuracy for the Whole of Europe

CNRS - 04 December 2013

An international team including CNRS, Météo-France, CEA, UVSQ and INERIS[1] has carried out and analyzed[2] a group of climate projections for the whole of Europe at an unprecedented resolution of 12 km, by downscaling the global simulations carried out for the 5th IPCC report. These simulations for the 21st century now provide a much more detailed representation of local phenomena and extreme events.

Himalayan Flowers Shed Light On Climate Change

The Reality Behind Europe's Response to Climate Change

Springer Science+Business Media - 25 November 2013

British cities -- unlike their counterparts on the mainland -- are taking the lead in making plans to curb and handle the impact of climate change. So says Diana Reckien, of Columbia University in the US, in a study published in Springer's journal Climatic Change that analysed the relevant strategic policies and planning documents of 200 urban areas in eleven European countries. They found that one in every three European cities has no plans on the table to reduce greenhouse gas emissions, while seven in every ten urban areas have no formal adaptation plans in place.

Ancient Minerals: Which Gave Rise to Life?

Carnegie Institution - 25 November 2013

Life originated as a result of natural processes that exploited early Earth's raw materials. Scientific models of life's origins almost always look to minerals for such essential tasks as the synthesis of life's molecular building blocks or the supply of metabolic energy. But this assumes that the mineral species found on Earth today are much the same as they were during Earth's first 550 million years -- the Hadean Eon -- when life emerged. A new analysis of Hadean mineralogy challenges that assumption.

Even If Emissions Stop, Carbon Dioxide Could Warm Earth for Centuries

Princeton University - 24 November 2013

Even if carbon dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to Princeton University-led research published in the journal Nature Climate Change. The study suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.

Unexpected Interaction Between Ocean Currents and Bacteria May Weaken Ocean's Ability to Absorb Carbon Dioxide

University of Southern Denmark - 13 September 2013

For the first time, researchers have successfully demonstrated an interaction between ocean currents and bacteria: The unexpected interaction leads to the production of vast amounts of nitrogen gas in the Pacific Ocean. This takes place in one of the largest oxygen free water masses in the world -- and these zones are expanding. This can ultimately weaken the ocean's ability to absorb CO2.

Movement of Marine Life Follows Speed and Direction of Climate Change

Princeton University - 12 September 2013

Scientists expect climate change and warmer oceans to push the fish that people rely on for food and income into new territory. Predictions of where and when species will relocate, however, are based on broad expectations about how animals will move and have often not played out in nature. New research based at Princeton University shows that the trick to more precise forecasts is to follow local temperature changes.

Why Are Some Corals Flourishing in a Time of Global Warming?

University at Buffalo - 10 September 2013

As Earth's temperature climbs, the stony corals that form the backbone of ocean reefs are in decline. It's a well-documented story: Violent storms and coral bleaching have all contributed to dwindling populations, and increasing acidity of seawater threatens to take an additional toll. Less discussed, however, is the plight of gorgonian corals -- softer, flexible, tree-like species that can rise up like an underwater forest, providing a canopy beneath which small fish and aquatic life of all kinds can thrive.

Ocean Fish Acquire More Mercury at Depth

University of Hawaii at Manoa - 25 August 2013

Mercury accumulation in the ocean fish we eat tends to take place at deeper depths, scientists found, in part because of photochemical reactions that break down organic mercury in well-lit surface waters. More of this accessible organic mercury is also being generated in deeper waters.

Arctic Sea Ice Update: Unlikely To Break Records, But Continuing Downward Trend

NASA - 23 August 2013

The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year. While the ice will continue to shrink until around mid-September, it is unlikely that this year’s summer low will break a new record. Still, this year’s melt rates are in line with the sustained decline of the Arctic ice cover observed by NASA and other satellites over the last several decades.
