The American Meteorological Society (AMS) held a discussion on the effects of climate change on Gulf Coast transportation and the New York City water supply. Michael Savonis, the air quality team leader of the Federal Highway Administration, said that those working in transportation are frequently conservative because of the billions of dollars involved, so considerations of investing in climate change preparation are tentative. But, as transportation infrastructure ages, climate change must be considered in building new roads, bridges, railways, and ports. The effects of climate change in the Gulf Coast area include a rise in average temperature between two and four degrees and a 50 percent increase in days with temperatures over 90 degrees. He said that as a result more than 2400 miles of roadways in the Gulf Coast area are at risk of permanent flooding as well as 75 percent of freight and non-freight port facilities. Because of the increase in heat, asphalt wears faster, train rails buckle more, and aircraft performance decreases. (more…)
