Global warming doubles risk of extreme La Nina event, study shows
The risk of extreme La Niña events in the Pacific Ocean could double due to global warming, new research has shown.
Data shows fewer tornado days in U.S. but more per event over past couple decades
Researchers predict global warming will cause an increase in frequency of Indian Ocean Dipole events
Warming climates intensify greenhouse gas given out by oceans
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fuelling further climate change, a study suggests.
Researchers find proof of global cooling after Chicxulub asteroid impact
No 'permanent El Nino,' scientists say—and the tropics may get even hotter
(Phys.org) —New research by Yale University scientists challenges a long-standing paradigm for temperature variability in the Pacific Ocean, casting doubt on the existence of a past period of "permanent" ...
Researchers quantify toxic ocean conditions during major extinction 93.9 million years ago
Oxygen in the atmosphere and ocean rose dramatically about 600 million years ago, coinciding with the first proliferation of animal life. Since then, numerous short lived biotic events—typically marked ...
Prehistoric climate change due to cosmic crash in Canada: Team reveals cause of global climate shift 12,900 years ago
For the first time, a dramatic global climate shift has been linked to the impact in Quebec of an asteroid or comet, Dartmouth researchers and their colleagues report in a new study. The cataclysmic event ...
British scientists offer explanations on global warming pause
Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
Scientists probe Canadian sulfide ore to confirm microbial activity in seawater 2.7 billion years ago
An analysis of sulfide ore deposits from one of the world's richest base-metal mines confirms that oxygen levels were extremely low on Earth 2.7 billion years ago, but also shows that microbes were actively ...
New, high-resolution global ocean circulation models identify trigger for Earth's last big freeze
For more than 30 years, climate scientists have debated whether flood waters from melting of the enormous Laurentide Ice Sheet, which ushered in the last major cold episode on Earth about 12,900 years ago, ...
Analyzing ocean mixing reveals insight on climate
Scientists at Los Alamos National Laboratory have developed a computer model that clarifies the complex processes driving ocean mixing in the vast eddies that swirl across hundreds of miles of open ocean.
Solving corrosive ocean mystery reveals future climate
Around 55 million years ago, an abrupt global warming event triggered a highly corrosive deep-water current through the North Atlantic Ocean. The current's origin puzzled scientists for a decade, but an international ...
