Preparing for Severe Climate Events: a Q+A with Drought Experts

, Kendall Science Fellow

In the most recent days and weeks when stories of floods and hurricanes have dominated the news, it might be easy to miss that 44% of the country is experiencing drought conditions. I am not a meteorologist—just an agricultural scientist obsessed with the weather—so I often wonder what happens in the weather room when there is a severe event, like a hurricane or tornado. Is it total chaos? Flashing lights and buzzing alarms? What about severe climate events that last longer than a few hours, such as drought? Read more >

Flooding, Extreme Weather, and Record Temperatures: How Global Warming Puts it All Together

, climate scientist

Even though Louisiana is not among the areas that has seen the most increase in heavy precipitation events, the Southeastern US has seen an increase of 27 percent from 1958 to 2012. The straightforward explanation for heavier downpours is that warmer air can contain more water vapor than cooler air. Indeed, global measurements show that there is more water vapor in the air now. It follows that there is more water to come down when it rains. Read more >

U.S. Braced for Historic Inland Flooding and Coastal Storm Surge Even As Joaquin Blew Out to Sea

, senior climate scientist

Hurricane Joaquin, while a category 4, unleashed torrential rain over the Bahamas, uprooting trees, disrupting power and ripping rooftops. Joaquin lingered in the tropics, shedding vast amounts of moisture that became part of a complex mix of weather systems in the eastern U.S., creating soggy conditions even before Joaquin shifted northeastward from the tropics offshore of the U.S., giving a one-two punch for the eastern states. Punch one was life-threatening inland flooding, and punch two was storm surge along coastal areas. Read more >

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

, former scientist and Kendall Science Fellow

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 >

Counting the Cost of Climate Disasters: What do Hurricane Sandy and Typhoon Haiyan Tell Us About What the U.S. and the Philippines Have in Common?

, deputy director, Climate & Energy Program

Angela Anderson, Director of the UCS Climate and Energy program, is in Warsaw for the latest round of international climate talks. In the political wake of typhoon Haiyan, she sent me this urgent dispatch about why developed and developing nations alike must consider the costs of climate impacts. And why she’s joined other activists who are fasting in solidarity with the Philippines’ chief negotiator: Read more >
