A U.S. government report is sounding the alarm about climate change.
Washington's 4th National Climate Assessment says that, if left unchecked -- climate change will cost the United States hundreds of billions of dollars.
The report adds climate change will also damage human health and quality of life, warning future risks... depend on decisions made today.
The White House said the report is inaccurate.
The report also comes a matter of days after President Trump -- commenting on a blast of icy November weather in Washington -- tweeted, "whatever happened to global warming?"
