Natural variations help resolve a climate puzzle

New research shows that naturally occurring climate variations help to explain a long-standing difference between climate models and satellite observations of global warming.

Climate change may not expand drylands

Does a warmer climate mean more dry land? For years, researchers projected that drylands—including deserts, savannas and shrublands—will expand as the planet warms, but new research from the Harvard John A. Paulson School ...

Best region for life on Mars was far below surface

The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes.

Past is key to predicting future climate, scientists say

In a review paper published in the journal Science, a group of climate experts make the case for including paleoclimate data in the development of climate models. Such models are used globally to assess the impacts of human-caused ...

How cold was the ice age? Researchers now know

A University of Arizona-led team has nailed down the temperature of the last ice age—the Last Glacial Maximum of 20,000 years ago—to about 46 degrees Fahrenheit (7.8 C).
