American Geophysical Union experts available to comment on science of heat waves

Sweltering temperatures dominated weather maps across the United States in July 2005 as a heat wave rolled over the country. Between July 12 and July 19, the heat sat over the southwest, where Arizona, California, Nevada, and New Mexico all experienced days of above-normal temperatures. By the following week, the heat had spread to the Midwest and East.

Several American Geophysical Union scientists are available throughout the summer season to comment on the science of heat waves and their possible impacts on humans and ecosystems, including the physical mechanisms behind heat waves, connections between climate change and extreme weather, and heat wave effects on water resources and public health.

Kate Evans leads the Computational Earth Sciences Group as part of the Computational Science and Engineering Division and the Climate Change Science Institute at Oak Ridge National Laboratory in Oak Ridge, Tennessee. She develops global climate models to use the world’s largest supercomputers and evaluates their fidelity to capture climate behavior at many scales. With these models, she studies the connections between global climate, weather anomalies and sea level rise.
