The Trump administration has revoked a scientific finding that climate change is a danger to public health, an idea that President Donald Trump called “a scam.”

The U.S. is the second-largest carbon polluter in the world, per EPA data, and the largest historical emitter of greenhouse gases.

When climate risk is systemic, there’s no bargain to be made: short-term “savings” don’t reduce household costs, they are repaid soon through higher bills. Rather than driving up the cost of living, climate policy helps to stop climate shocks from raising prices even faster.

Promising to challenge the action in court “where evidence matters,” environmental advocates signaled a major legal fight likely to end up before the Supreme Court.

If you don’t get away from this green scam, your country is going to fail,' Trump told more than 150 world leaders.

The EPA’s repeal of the “endangerment finding” could threaten automakers and oil companies — if it survives in court.
