The congressionally mandated report by 13 federal agencies, the first of its kind under the Trump administration, found that climate change is already being felt in communities across the United States.
The National Climate Assessment finds that extreme weather disasters "have already become more frequent, intense, widespread or of long duration and have cost the the USA almost $400 billion since 2015".
Report co-author Katharine Hayhoe says it shows the risky weather that scientists said will happen in the United States is already happening.
The Trump did not block the release of the report, a product of more than two years of work by more than 300 of the nation's leading scientists both in and outside of government, and is one volume of the National Climate Assessment, which the federal government is required by law to produce every four years.
It said global warming would disproportionately hurt the poor, broadly undermine human health, damage infrastructure, limit the availability of water, alter coastlines, and boost costs in industries from farming to energy production.
However, David Reidmiller, the director of the assessment, said the timing was in order to have the report come out ahead of United Nations climate talks, which begin in Poland on December 2, according to Axios.
While it said that numerous impacts of climate change - including more frequent and more powerful storms, droughts and flooding - were already underway, the projections of further damage could change if greenhouse gas emissions were sharply curbed.
Releasing the report on Black Friday "is a transparent attempt by the Trump Administration to bury this report and continue the campaign of not only denying but suppressing the best of climate science", said study co-author Andrew Light, an global policy expert at the World Resources Institute.
Report co-author Donald Wuebbles, a University of IL climate scientist, said things will just get worse from here. Ahead of the Thanksgiving holiday, Trump antagonized climate scientists by tweeting, once again, that he believes cold weather disproves long-term trends of a warming climate. She said global warming is already harming people's health, but it will only get worse.
Study co-author Andrew Light, an worldwide policy expert at the World Resources Institute, told The Associated Press that the release " "is a transparent attempt by the Trump administration to bury this report and continue the campaign of not only denying but suppressing the best of climate science".
Previous research, including from United States government scientists, has also concluded climate change could have severe economic consequences, including damage to infrastructure, water supplies and agriculture.
The timing of report's publication also raised questions about White House interference.
That includes worsening air pollution causing heart and lung problems, more diseases from insects, the potential for a jump in deaths during heat waves, and nastier allergies.
