Scientists say the chance of every volcano erupting at once is so small that it's impossible, but what if it did happen? Would Earth as it now exists survive?

A look at five places that will help push 2014 into the global warming record books.

California and Nevada will feel an Arctic chill this week when wintry air from Canada arrives on New Year's Eve, possibly setting new record-cold temperatures as revelers ring in the New Year.

As the 10th anniversary of the Indian Ocean tsunami approaches on Dec. 26, greatly expanded networks of seismic monitors and ocean buoys are on alert for the next killer wave.

Caltech professor Don Anderson died of cancer on Dec. 2, but he had the last word. Literally.

Football, NASCAR and their rowdy, roaring crowds were pitted in a head-to-head battle this year to see which sport hits highest on the seismic charts.

The "atmospheric rivers" that can bring torrential rains to Northern California will double in frequency by the year 2100 because of climate change, researchers say.

Greenland's disappearing ice shifted gears in the past decade, switching from shrinking glaciers to surface melting, researchers reported at the American Geophysical Union's annual meeting.

Boulders the size of stretch limousines were moved by storm waves during Super Typhoon Haiyan.

Volcanoes punched through a remote part of the West Antarctic ice sheet twice in the last 50,000 years.

New, more precise dates for India's Deccan Traps eruptions could revive the idea that the massive set of lava flows caused the Cretaceous-Tertiary (K-T) extinction.

Natural temperature swings in the ocean, not global warming, are driving California's extreme drought, according to a new government study.

The 2012-2014 California drought is the worst to parch central and southern California in the past 1,200 years.
