In a rapidly changing Arctic, the area might serve as a refuge—a place that could continue to harbor ice-dependent species when conditions in nearby areas become inhospitable. The region ...
Today’s weather forecasts come from some of the most powerful computers on Earth. The huge machines churn through millions of calculations to solve equations to predict temperature, wind,...
Modern-day computer simulations and historic observations from 100-year old ship logbooks have extended estimates of Arctic sea ice volume all the way back to 1901, researchers report.
The idea that the young Earth had a thicker atmosphere turns out to be wrong. Researchers used bubbles trapped in rocks to show that the air 2.7 billion years ago exerted at most half the...
