Sea ice could stabilize or even expand for periods of several years, but it will ultimately melt as the climate warms.

A new study involving NCAR's Bette Otto-Bliesner looks at rising sea levels during the warmth of the last interglacial period (130,000 to 120,000 years ago) and finds that melting ice sheets contributed far more to rising sea levels than thermal expansion.

If you’re an American, it’s tough to avoid corn. This ubiquitous starch turns up in soft drinks, compostable cups, and automobile fuel—and even plays a role in U.S. heat waves, including the intense one of 2011.

The Sun drives our climate, so a slowdown in solar activity would surely put the brakes on global warming—wouldn’t it? That question percolated through the media following a set of reports from a solar physics meeting.
