Study Sounds ‘El Niño Alarm’ For Late This Year

Study Sounds ‘El Niño Alarm’ For Late This Year

Although they occur in the equatorial tropical Pacific Ocean, the effects of El Niño events can reverberate around the globe, wreaking havoc with typical weather patterns. El Niños can cause California to be pummeled by Pacific storm systems, for example, while leaving eastern Australia at greater risk of drought.… Read More

‘Atmospheric River’ May Put a Dent in California Drought

‘Atmospheric River’ May Put a Dent in California Drought

The most severely dry soils in California are in Central and Northern California, which means the storms hitting during the next few days are likely to target the areas where precipitation is most sorely needed, Murphy said. If the drought continues through the rest of the wet season, it could reverberate throughout the U.S. economy, considering th… Read More

Time is Running Out for California Drought Relief

Time is Running Out for California Drought Relief

More than halfway through the state's wet season and the Sierra Nevada snowcap all but non-existent, California's prospects for making up its precipitation deficit are slim. The snowcap will yield precious little water and the state would need to get about a foot or more of rain in the next two months to make up the difference. Forecasts are not of… Read More

Obama’s State of the Union Climate Mention Fits Pattern

“Over the past eight years, the United States has reduced our total carbon pollution more than any other nation on Earth,” Obama said. “But we have to act with more urgency — because a changing climate is already harming western communities struggling with drought, and coastal cities dealing with floods.”… Read More

Polar Vortex Is Back: Coldest of the Cold En Route to U.S.

Polar Vortex Is Back: Coldest of the Cold En Route to U.S.

Of course, blaming this all on the polar vortex isn’t entirely accurate. The true polar vortex exists at upper levels of the atmosphere, and what’s been causing January’s bitter cold - and soon to be February’s - is a result of the interaction between the vortex and events in the more chaotic lower atmosphere. The polar vortex exists at the upper … Read More
