Six Key Facts Ignored in Dismissal of California Climate Suits vs. Fossil Fuel Companies

, climate accountability campaign manager

This week, U.S. District Judge William Alsup dismissed lawsuits by San Francisco and Oakland seeking to hold fossil fuel companies accountable for their contributions to climate change. Judge Alsup’s ruling dangerously rested on balancing climate harms with fossil energy benefits, deferred to legislative- and executive-branch solutions that major fossil fuel companies have spent millions opposing, seriously underplayed the role of ExxonMobil and others in spreading disinformation about climate science and policy, and punted on the question of who should pay for climate damages.

ExxonMobil’s Jekyll-and-Hyde Act: A Year in Holding Fossil Fuel Companies Accountable

, climate accountability campaign manager

Just a few weeks into the new year, ExxonMobil has turned the page on 2017—a year of significant gains for corporate climate accountability and significant setbacks for major fossil energy companies. However, some of these companies are aggressively fighting back, continuing to spread climate disinformation and refusing to plan for a low-carbon future. ExxonMobil, in particular, has moved toward countersuing California communities that are suing it and other fossil fuel producers over climate-related damages, and launched a webpage and video attacking the #ExxonKnew campaign. ExxonMobil’s retaliation against advocates for climate action and corporate accountability is a sure sign that our work is having an impact, and that now is the time to redouble our efforts.

What’s the Connection Between Climate Change and Hurricane Harvey?

, senior climate scientist

As Hurricane Harvey slipped back offshore of Texas and then like a pinwheel spun back over to Louisiana and is now moving further inland on a northeast trajectory, questions are already being asked: Is this storm unprecedented? Are there telltale signs of climate change? Read more >

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

, former 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).
