Crazy Hot Days, Crazy Warm Nights: A New Study on Climate Change in California’s Central Valley

, scientist and Kendall Science Fellow

Last week I, along with an international group of scientists, published a study in the journal Climatic Change in which we found that the hottest summer days (24 hour periods) in the Central Valley were twice as likely to occur due to climate change. Heat waves in California’s Central Valley have become progressively more severe in recent decades due to  higher humidity and warmer nighttime temperatures. Observations obtained from NOAA’s National Climatic Data Center show that Central Valley nighttime temperatures were nearly 2°F (1°C) warmer in the 2000s compared to the 1901-1960 average and even higher for the whole of California (see plot below).

Are the California Wildfires a Sign of Climate Change?

, scientist and Kendall Science Fellow

The exceptional heat in Southern California and the dangerous wildfires occurring since May 13 may be a sign of climate change given their severity and timing. As of Friday, May 16, over 10,000 acres have burned throughout Southern California and several locations have surpassed previous temperature records. Read more >

The Silent Killer: Extreme Heat in the Western U.S.

, scientist and Kendall Science Fellow

The National Climate Assessment (NCA) makes an important statement: the trends in heat waves for the western U.S. are alarmingly clear and pose a major threat for the local population. Heat waves are becoming more common and more severe in this region and their increase in frequency and severity is consistent with a warming world. Read more >

Energy-Water Collisions: Our 2013 Update

, senior energy analyst, Clean Energy

While a lot of folks are rightly focused on the House-Senate budget collision in D.C. right now, I’ve been thinking (as is my wont) about collisions of a different sort: between power plants and the rivers and lakes they depend on. Read more >
