Volcanic eruptions durably impact North Atlantic climate

Particles emitted during major volcanic eruptions cool the atmosphere due to a 'parasol' effect that reflects sunlight. The direct impact of these particles in the atmosphere is fairly short, lasting two to three years. However, ...

Climate change does not cause extreme winters, new study shows

Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists at ETH Zurich and the California Institute of Technology have shown that global warming actually ...

VISTA stares right through the Milky Way

A new image taken with ESO's VISTA survey telescope reveals the Trifid Nebula in a new light. By observing in infrared light, astronomers can see right through the central parts of the Milky Way and spot many previously hidden ...

Climate models don't over-predict warming, study shows

If you listen to climate change skeptics, Earth's surface hasn't warmed appreciably in the last 15 years, and any "record" set last year is just the result of the planet doing what the planet naturally does.

Environmental 'tipping points' key to predicting extinctions

Researchers from North Carolina State University have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population's adaptive ...

How variable are ocean temperatures?

The earth's climate appears to have been more variable over the past 7,000 years than often thought. This is the conclusion of a new study forthcoming online this week in the U.S. scientific journal Proceedings of the National ...
