More summer sunshine leading to increased Greenland ice melt

Wed, 06/28/2017 - 13:49
A marked decrease in summer cloud cover during the last 20 years has significantly accelerated melt from the Greenland ice sheet, a team of researchers has concluded.

Climate change impacts Antarctic biodiversity habitat

Wed, 06/28/2017 - 12:14
Ice-free areas of Antarctica -- home to more than 99 percent of the continent's terrestrial plants and animals -- could expand by more than 17,000 km2 by the end of this century, a study reveals. The study is among the first to investigate how ice-free areas in Antarctica may be affected by climate change.

As climate stirs Arctic sea ice faster, pollution tags along

Tue, 06/27/2017 - 09:53
A warming climate is not just melting the Arctic's sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country's waters, says a new study.

Collapse of European ice sheet caused chaos in past

Mon, 06/26/2017 - 17:05
Scientists have reconstructed in detail the collapse of the Eurasian ice sheet at the end of the last ice age. The big melt wreaked havoc across the European continent, driving home the original Brexit 10,000 years ago.

Animals, not drought, shaped our ancestors' environment

Mon, 06/26/2017 - 14:57
The expansion of grasslands isn't solely due to drought, but more complex climate factors are at work, both for modern Africans now and ancient Africans in the Pleistocene, suggests new research.

Evidence for past large earthquakes in the Eastern Tennessee seismic zone

Mon, 06/26/2017 - 11:46
The Eastern Tennessee Seismic Zone (ETSZ), a zone of small earthquakes stretching from northeastern Alabama to southwestern Virginia, may have generated earthquakes of magnitude 6 or greater within the last 25,000 years, according to a new study.

Monitoring changes in wetland extent can help predict the rate of climate change

Mon, 06/26/2017 - 11:45
Monitoring changes to the amount of wetlands in regions where permafrost is thawing should be at the forefront of efforts to predict future rates of climate change, new research shows.

Tipping points are real: Gradual changes in CO2 levels can induce abrupt climate changes

Fri, 06/23/2017 - 09:04
During the last glacial period, within only a few decades the influence of atmospheric CO2 on the North Atlantic circulation resulted in temperature increases of up to 10 degrees Celsius in Greenland -- as indicated by new climate calculations.

Accelerating rate of temperature rise in the Pyrenees

Wed, 06/21/2017 - 09:31
The Iberian Peninsula is undergoing climate change, with temperatures on the rise, and mountain ranges are not exempt from this trend. A team of scientists has analyzed regional climate series from the Central Pyrenees for 1910 to 2013 (the most extensive climate records to date for the area), concluding that temperatures have risen at an increasing rate since 1970, particularly in spring and summer.

Ocean predicts future northwestern European and Arctic climate

Wed, 06/21/2017 - 09:01
There is a clear potential for practical and useful predictions of northwestern European and Arctic climate based on the state of the ocean, new research indicates.

Great opportunities for marine research with new underwater vehicle

Tue, 06/20/2017 - 08:45
An autonomous underwater vehicle offers promise for advanced marine research use. This will make it possible to conduct detailed studies of the seabed at great depths and track the climate thousands of years back in time, say researchers.

Wet and stormy weather lashed California coast... 8,200 years ago

Tue, 06/20/2017 - 08:32
An analysis of stalagmite records from White Moon Cave in the Santa Cruz Mountains shows that 8200 years ago the California coast underwent 150 years of exceptionally wet and stormy weather. This is the first high resolution record of how the Holocene cold snap affected the California climate.

Scientists throw light on mysterious ice age temperature jumps

Mon, 06/19/2017 - 11:58
Scientists believe they have discovered the reason behind mysterious changes to the climate that saw temperatures fluctuate by up to 15°C within just a few decades during the ice age periods.

Widespread snowmelt in West Antarctica during unusually warm summer

Thu, 06/15/2017 - 07:46
An area of West Antarctica more than twice the size of California partially melted in 2016 when warm winds forced by an especially strong El Nino blew over the continent.

Animal evolution: Hot start, followed by cold shock

Thu, 06/15/2017 - 07:45
The initial phases of animal evolution proceeded faster than hitherto supposed: New analyses suggest that the first animal phyla emerged in rapid succession -- prior to the global Ice Age that set in around 700 million years ago.

Ancient otter tooth found in Mexico suggests mammals migrated across America

Wed, 06/14/2017 - 08:29
An ancient otter tooth recently discovered in Mexico suggests certain mammals migrated across America during the Miocene geologic epoch, roughly 23 million to 5.3 million years ago. The new hypothesized route questions other theories such as migrations above Canada and through Panama, and has implications for a much larger biologic event -- the Great American Biotic Interchange, when land bridges were formed and animals dispersed to and from North America and South America.

Polar bears' declining mercury levels likely due to climate-related shifts

Wed, 06/14/2017 - 08:18
To understand how human activities are affecting the planet, scientists often study the health of animals in the wild. Now a new study finds that the levels of mercury in some polar bears are declining. But rather than heralding a drop in mercury in the environment, the decrease could indicate how climate change has led the animals to shift foraging habits, which has affected their diets and weight.

Large Canadian Arctic climate change study cancelled due to climate change

Tue, 06/13/2017 - 14:06
The Science Team of the Canadian Research Icebreaker CCGS Amundsen has cancelled the first leg of the 2017 Expedition due to complications associated with the southward motion of hazardous Arctic sea ice, caused by climate change.

Comets may have delivered significant portions of Earth's xenon

Thu, 06/08/2017 - 13:55
A new study suggests that roughly 22% of the element xenon found in Earth's atmosphere may have come from comets.

Sahara greening may intensify tropical cyclone activity worldwide

Thu, 06/08/2017 - 06:33
Future climate warming could lead to a re-greening of the southernmost Sahara (Sahel), with decreased dust emissions and changes in land cover. In a recent study, researchers have found that tropical cyclone activity may have increased during past warm climates in connection with a greening of the Sahara.
