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

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).

You Can Help Investigate the Link between Climate Change and Extreme Weather Events

The power of citizen science has pushed the boundary on what climate science can tell us about our changing climate, including extreme events. If you have a computer, you can help us advance the science and make connections between climate change and extreme events. Please join me and thousands of others on this journey — become a citizen scientist today! Read More

The Bering Sea Bomb and the Polar Vortex in our Warming World

A historic storm occurred over Alaska this past weekend as typhoon Nuri merged with an extra tropical system and became a perfect storm. With it also came the chance for more extreme weather for the United States in the form of a small polar vortex event that flooded much of eastern North America with frigid temperatures. But how can we have such cold outbreaks in our warming world? Read More

The Ocean’s Cooling Effect: An Air Conditioner for the Planet

The tropical Pacific Ocean has been acting as a type of air conditioner for the planet during the past decade and a half by slowing the rate of global warming. Recent research suggests that the “speed bump” is in large part due to cooler-than-average sea surface temperatures. Read More

Holding Big Carbon Accountable: Response to Severin Borenstein

Respected UC Berkeley economist Dr. Severin Borenstein released a blog yesterday that included at least one point we can agree on: fossil fuels are cheap. But Borenstein missed the boat in dismissing significant new research that traces 63 percent of heat-trapping emissions to just 90 institutions, including oil giants Exxon-Mobil, BP, and California-based Chevron, suggesting that holding fossil fuel producers accountable is a “copout.”  Read More

Who Is Responsible for Climate Change? New Study Identifies the Top 90 Producers of Industrial Carbon Emissions

Today’s publication in the journal Climatic Change by Richard Heede on Tracing anthropogenic carbon dioxide and methane emissions to fossil fuel and cement producers, 1854–2010 provides a robust scientific basis for motivating fresh thinking and dialogue about responsibility for taking action to address climate change.
