Human cause of global warming is near certainty, UN reports
Global warming is unequivocal, human influence has been the dominant cause since the mid-20th century, and atmospheric concentrations of greenhouse gases, already at levels not seen in at least 800,000 years, ...
Arctic warmth unprecedented in 44,000 years, reveals ancient moss
When the temperature rises on Baffin Island, in the Canadian high Arctic, ancient Polytrichum mosses, trapped beneath the ice for thousands of years, are exposed. Using radiocarbon dating, new research in Geophysical Research Le ...
Global warming: The conversation we need to have
We all know the earth's climate is changing. The effects are inescapable no matter where we live. Here in New England, some changes are subtle (more humidity, consistently warmer nights), dramatic (more intense ...
Weakened 'polar vortex' blamed for N. American chill
The bitter chill gripping North America is a result of Arctic air that has spilled southwards, and global warming may be a cause, an expert said on Monday.
An icebreaker gets stuck in the ice, photos are used to mislead
As the saying goes, a picture is worth a thousand words, and by now you might have seen dramatic images of passengers on stranded icebreaker Akademik Shokalskiy being rescued by helicopter last Friday after becoming lodged in Antarctica sea ice on Christmas Eve. ...
Arctic cyclones more common than previously thought
From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes—and melting sea ice in the Arctic Ocean.
Experiment is first to simulate warming of Arctic permafrost
Although vegetation growth in the Arctic is boosted by global warming, it's not enough to offset the carbon released by the thawing of the permafrost beneath the surface, University of Florida researchers have found in the ...
Ex-NASA expert issues call for climate solutions
Longtime NASA expert James Hansen has issued a call for new approaches to stop global warming, saying solutions are needed and that currently accepted targets are too dangerous.
Researchers find significant amount of methane escaping East Siberian Arctic Shelf
'Missing heat' discovery prompts new estimate of global warming
An interdisciplinary team of researchers say they have found 'missing heat' in the climate system, casting doubt on suggestions that global warming has slowed or stopped over the past decade.
Testing a relationship: Arctic warming and China's summer monsoon
(Phys.org) —In the late 1970s, eastern China experienced a shift in the summer monsoon circulation causing a "North-drought/South-flood" trend. In two related studies, researchers at Pacific Northwest National ...
Arctic sea ice minimum in 2013 is sixth lowest on record (Update)
After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center ...
The Arctic is especially sensitive to black carbon emissions from within the region
Black carbon, also known as soot, emitted from combustion of fuels and biomass burning, absorbs solar radiation in the atmosphere and is one of the major causes of global warming, after carbon dioxide emissions. When black ...
Study predicts an ice-free Arctic by the 2050s
(Phys.org) —Accelerated climate warming propelled by greenhouse gas emissions could bring an ice-free September to the Arctic by 2054, a University at Albany scientist predicts.
