Scientists at the U.S. Geological Survey were directed to use computer-generated models that only project climate change impacts through 2040. The scientists had previously modeled climate change impacts through 2100, which experts say provides a more accurate picture of climate change because the effects of current greenhouse gas emissions will primarily be felt after 2040.

Under the Trump Administration, 1.6 million acres of the Arctic National Wildlife Refuge in Alaska has been opened up for oil drilling. In the rush to complete the environmental review process before leasing can begin, scientists have been repeatedly ignored and sidelined.
