EPA Administrator Lee Zeldin said Tuesday he's issuing draft plans to overturn the agency's 2009 scientific finding that greenhouse gases threaten human health and welfare — a move guaranteed to spark litigation.

In Illinois and the rest of the country, extreme heat, flooding and tornadoes have accelerated with climate change. Critics vow to sue.

The endangerment finding underpins the EPA’s ability to regulate greenhouse gases. The Trump administration is trying to reverse it.
