Midwest Climate Change to be Severe
Indiana News Service
INDIANAPOLIS - Parts of the country along the coasts have been battered this year by Mother Nature, and a new study from the Midwest Economic Policy Institute warns that the threat of climate change extends much farther inland and could wreak havoc on transportation and infrastructure systems across the Midwest.
Her report says the average air temperature has increased by more than 4 degrees since the 1980s, and there›s been a 27 percent increase in the number of days of very heavy rain since the 1950s.
Flooding is a key issue because there has been a steady reduction in ice coverage on the Great Lakes, and more frequent freeze-thaw cycles.
Craighead says there have been more electricity outages, and she adds the Midwest is a net distributor of electricity to other regions.
Floods, high winds, ice, snow and storms can damage facilities and above-ground transmission lines.
The study says national infrastructure needs are expected to top $2 trillion by 2025.
It notes the state departments of transportation in Illinois, Michigan, Ohio and Minnesota have all pursued asset-management programs to address climate change and assess vulnerabilities.
