Doubt cast on global firestorm generated by dino-killing asteroid
Pioneering new research has debunked the theory that the asteroid that is thought to have led to the extinction of dinosaurs also caused vast global firestorms that ravaged planet Earth.
Two lakes beneath the ice in Greenland, gone within weeks
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly drained away.
Researchers find levels of nitrogen in meteorites similar to levels in Earth's atmosphere
Tiny plant fossils a window into Earth's landscape millions of years ago
Minuscule, fossilized pieces of plants could tell a detailed story of what the Earth looked like 50 million years ago.
Acceleration in sea level rise far larger than initially thought, study shows
The acceleration in global sea level from the 20th century to the last two decades has been significantly larger than scientists previously thought, according to a new Harvard study.
Study shows how meltwater on Greenland's ice sheet contribute to rising sea levels
As the largest single chunk of melting snow and ice in the world, the massive ice sheet that covers about 80 percent of Greenland is recognized as the biggest potential contributor to rising sea levels due ...
Erratic as normal: Arctic sea ice loss expected to be bumpy in the short term
Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change—and rapid change—at ...
Scientists use ocean waves to monitor offshore oil and gas fields
A technology developed by Stanford scientists for passively probing the seafloor using weak seismic waves generated by the ocean could revolutionize offshore oil and natural gas extraction by providing real-time ...
Smothered oceans: Extreme oxygen loss in oceans accompanied past global climate change
Seafloor sediment cores reveal abrupt, extensive loss of oxygen in the ocean when ice sheets melted roughly 10,000-17,000 years ago,according to a study from the University of California, Davis. Thefindings ...
Winters in Siberian permafrost regions have warmed since millenia
For the first time, researchers at the Alfred Wegener Institute have successfully decoded climate data from old permafrost ground ice and reconstructed the development of winter temperatures in Russia's Lena ...
Climate models disagree on why temperature 'wiggles' occur
A new Duke University-led study finds that most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms. The models ...
Warm ocean melting East Antarctica's largest glacier
The largest glacier in East Antarctica, containing ice equivalent to a six-metre (20-foot) rise in global sea levels, is melting due to warm ocean water, Australian scientists said on Monday.
A 3-D view of the Greenland Ice Sheet opens window on ice history
Scientists using ice-penetrating radar data collected by NASA's Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening ...
Geologists solve mystery of Tibetan mountains
In the most comprehensive study of its kind, University of Kansas geologists have unraveled one of the geologic mysteries of Tibet. The research, recently published online in Nature Geoscience, shows that i ...
