"Snowball Earth" Might Have Been Slushy

GISS climate modelers go back in time to simulate past "Snowball Earth" conditions of 720 to 635 million years ago and find that complete freeze-over is hard to achieve. (2015-08-04)

Why So Many Global Temperature Records?

You could hardly miss the media stories about how the past year ranked in terms of global temperatures. Astute readers may ask: how do different institutions come up with slightly different numbers for the same planet? (2015-01-21)

Rising Temperatures: A Month Versus a Decade

You may have heard that September 2014 was the warmest on record. But how meaningful is it when you hear that a recent month or season broke temperature records? (2014-10-23)

In a Warming World, the Storms May Be Fewer But Stronger

Extreme storms prompt questions about whether climate change is affecting weather intensity. Satellites, statistics, and models are teaching us a lot about what we know and do not know about such storms. (2013-03-15)

Storms in the Machine

To estimate the odds of a major typhoon striking a coastal region and how climate change may shift those odds, a statistical model examines how the El Niño cycle affects storm generation and behavior. (2012-11-21)

Fresh Air for the Future

A study of tropospheric ozone and black carbon, pollutants from human activities which disrupt Earth's climate, shows that emission control measures could prevent millions of premature deaths by the year 2030. (2012-10-10)

Far-Out Photosynthesis

As we search for habitable planets in other solar systems, how similar can we expect the optical signs of photosynthesis to be those of Earth? (Feb '12)

From Ash in the Wind to Smoke from the Stack

Aerosols don't just come from spray cans. Any airborne particle or droplet, whether from a canister, the smokestack of a factory, or a dust storm, is an aerosol. (Apr '10)

Earth's Temperature Tracker

After tracking Earth temperature for decades, NASA scientist James Hansen is confident the global warming trend observed since 1880 is mainly the result of human-produced greenhouse gases. (Nov '07)

Methane: Climate Super-Star

In 30 years, our knowledge of methane has traveled from obscure trace gas to important greenhouse forcing, both natural and anthropogenic. What caused this change, and what role has methane played in climate, both in the past and future. (Sep. '04)

Atmospheric Tango

Ozone affects climate, and climate affects ozone. Temperature, humidity, winds, and the presence of other chemicals in the atmosphere influence ozone formation, and the presence of ozone, in turn, affects those atmospheric constituents. (Feb. '04)
