Abt Associates: Bold thinkers driving real-world impact
In its third edition of Climate Change Indicators in the United States—a report supported in part with data from Abt Associates and released by the U.S. Environmental Protection Agency (EPA) last week—more than 30 indicators of climate change demonstrate that global warming is already affecting the environment and society worldwide.
“We developed 10 indicators of climate change which show that climate change is an ongoing reality,” said Dr. James Palardy, an associate at Abt Associates who directed the project involving analysis and reporting of observed data on key environmental measures.
Abt Associates refined existing indicators reflecting changes in ozone concentrations and extreme temperatures, and developed four new indicators at a national scale: wildfire frequency and severity, the spread of Lyme disease, changes in the number of days during which either air conditioning or heat are required and water levels and, on a regional scale, temperatures of the Great Lakes.
Abt also developed indicators for several regional features in the report, including measures of drought in the Southwest, changes in the date of peak cherry blossom bloom in Washington, D.C., and changes in the date of river ice break-up in Alaska.
EPA’s Indicators report was last published in 2012.
