A new climate bill making its way through the House has a provision in it that would allow Americans to sue businesses or the government if they think they've been harmed by global warming.
Environmentalists say the bill was developed to try and force the government to curb carbon emissions.
Still, others say the legislation will open the door for anyone to sue over anything.
"It's an insane bill that's meant to protect nobody but lawyers, and what's the one group pretty much everyone in Congress belongs to? It's lawyers," said Dan Gainor of the Business and Media Institute. "It's silly environmental legislation designed to ultimately cost ordinary people a lot of money."
The bill was written by Democrats Henry Waxman of California and Edward Markey of Massachusetts.
