A new study shows that there could be an unexpected side effect of climate change happening right under your feet. Researchers at Northwestern University used temperature sensors underground across Chicago and found that the city's concrete structures (think parking garages, basements, or train tunnels) are absorbing heat from rising temperatures, and it's causing the city to slowly sink.
At least seven people were killed Monday after a “superfog” of smoke from marsh fires and dense morning fog caused a series of wrecks on Interstate 55 near New Orleans.
