Ready for a ’90s El Niño flashback?

Researchers are keeping a close eye on a giant pool of abnormally warm water in the Pacific Ocean that some think could trigger another El Niño of epic proportions if it rises to the surface, sending weather patterns into a tizzy around the world.

That could mean heavy rains in drought-stricken California, dry weather across the Midwest and East Coast, and parched landscapes in Australia and South Africa while it pours in South America. The phenomenon is linked to the periodic warming of surface waters in the eastern tropical Pacific Ocean.

Be Prepared: ‘Extreme’ El Nino Events to Double, Study Says

During February 1998, a powerful jet stream pounded California with an unrelenting series of wet Pacific storms. Longstanding rainfall records fell. Oceanfront homes slumped into the roiling surf. Roads washed out across the state. Federal disaster areas were declared in 35 counties. At least 17 people died. The Red Cross opened 79 shelters and fed more than 100,000 people.

The culprit? An extreme El Niño, a phenomenon triggered by a warming of waters in the equatorial Pacific Ocean that shifts weather patterns around the world.

El Niño’s ills weren’t confined to California: In 1997-98, torrential rains washed away villages in northern Peru, heat waves rolled across Australia, and massive peat-bog fires cloaked Indonesia in a thick haze. All told, the impacts caused upwards of $45 billion in global economic losses and claimed an estimated 23,000 lives.

Earth Spun Faster in 2009 Due to Ocean Current?

Did it feel like time flew in November 2009? It turns out the days were actually going a wee bit faster for part of that month, according to a team of NASA and European scientists.

Earth spun about 0.1 millisecond faster for a two-week stretch, said study co-author Steven Marcus, a researcher at NASA’s Jet Propulsion Laboratory in Pasadena, California.

The planet’s speedier spin appears to have been due to a slowdown in an ocean current that whips around Antarctica.

Batten down the hatches: A “very active” Atlantic hurricane season is brewing, and at least one major storm is likely to strike the U.S. coastline, experts said today.

The hurricane forecast team at Colorado State University in Fort Collins anticipates 17 named storms to form in the Atlantic between June 1 and November 30.
