Canada's oil sands CO2 emissions are significantly higher than indicated by industry data collected using internationally recommended methods, according to a study published Tuesday.
Environment Canada scientists flying over the region took atmospheric measurements and found CO2 emission intensities up to 123...
Yosemite National Park contains some of the world's most iconic landforms, including Half Dome, Yosemite Falls, and El Capitan. Although the cliffs of Yosemite Valley may appear static, rockfalls from these cliffs are common, with a rockfall occurring every...
A gigantic cavity—two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall—growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier....
The threshold for dangerous global warming will likely be crossed between 2027 and 2042 -- a much narrower window than the Intergovernmental Panel on Climate Change's estimate of between now and 2052. In a study published in Climate Dynamics, researchers...
A new study suggests the Western Antarctic Ice Sheet is less stable than researchers once thought. As in the past, its collapse in the future is likely.
The finding is based in part on the results of a paper published...
Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study reported in the journal One Earth on October 15 combining climate modeling and the...
New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth's axis was approaching higher values.
During these times, longer and stronger summers melted the large Northern Hemisphere...
Glaciers in the Southern Alps of New Zealand have lost more ice mass since pre-industrial times than remains today, according to a new study.
Research led by the University of Leeds, in collaboration with the National Institute of Water and...
Strategies for limiting climate change must take into account their potential impact on water quality through nutrient overload, according to a new study from Carnegie's Eva Sinha and Anna Michalak published by Nature Communications. Some efforts at reducing carbon emissions...
The growth of forest trees all over the world is becoming more water-limited as the climate warms, according to new research from an international team that includes University of Arizona scientists.
The effect is most evident in northern climates and...
A major study into an ancient climate change event that affected a significant percentage of Earth's oceans has brought into sharp focus a lesser-known villain in global warming: oxygen depletion.
The study, just published in the prestigious Proceedings of the National...
