EPA Administrator Lee Zeldin on Sunday defended the Trump administration’s move to repeal the so-called endangerment finding and cast doubt that greenhouse gas emissions endangers human health.

President Donald Trump’s administration has proposed revoking a scientific finding that's long been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change.

Most of the United States’ major climate regulations are underpinned by one important document: It’s called the endangerment finding, and it concludes that greenhouse gas emissions are a threat to human health and welfare.
