Faced with a president who has called global warming a hoax, officials have filed dozens of suits against oil companies to try to cover the costs of extreme weather.

The justices are about to hear a lawsuit that could determine whether the oil industry faces billions of dollars in liability for damages caused by global warming.

A federal judge ruled that the new law, which would force fossil fuel companies to pay $75 billion to help cover the costs of climate change, was unconstitutional.

A group of civil-rights and free-speech lawyers accused the judge of bias and “general incompetence.”

The National Academies of Sciences, Engineering and Medicine had been under pressure from Republican leaders, including President Trump.

Roger Worthington is helping to lead a $50 billion lawsuit against oil producers. This week he’ll face powerful critics in Congress.

The case could have significant bearing on a range of other lawsuits brought against the fossil fuel industry by cities and states across the country.
