The election of Donald J. Trump as U.S. president, a candidate who called human -
driven climate change a hoax, was followed by Trump naming more and more climate - change doubters to run the government's environment and energy agencies.
The fact that Trump has called global warming a «
hoax» was mentioned in nearly a quarter of all segments about
climate change on the nightly news and Sunday morning programs on ABC, CBS, and NBC in 2017 — and in more than a third of those instances, the networks didn't push back by affirming that human -
driven climate change is a reality.
