Last year, Trump announced he would withdraw the United States from the 2015 Paris Deal to combat climate change.

A long-awaited climate report that the Trump administration released on Black Friday reportedly in an attempt to bury the news, shows that climate change is already having a dramatic effect on life in the USA, and that among the things it will damage is the American economy. A White House spokeswoman said the assessment was "based on the most extreme scenario", although the report explores the differences in the impacts of climate change based on pollution levels and other factors.

"We are seeing the things we said would be happening, happen now in real life", said another co-author Katharine Hayhoe of Texas Tech University. Alexandria Ocasio-Cortez, the newly elected U.S. congresswoman who's already pushing for better and more aggressive climate action, was among Democratic leaders demanding action in the wake of the report's release. "That being said, all hope is not lost, but we must act now".

Indeed, the White House report dismissed the idea, pushed by President Donald Trump himself among others, that cold weather suggests that global warming might not be occurring. Prepared by hundreds of scientists and officially made public on November 23, the second volume of the Fourth National Climate Assessment focuses on "Impacts, Risks, and Adaptation in the United States".

"Continuing to damage" means climate change already causing problems, present tense.

The report goes on to predict that climate change will be especially costly on the nation's coasts, with rising seas and severe storm surges, leading to lower property values. "That affects our jet stream pattern and counterintuitively might lead to more extremes on both sides - whether it be drought and flood, or cold and warm - because we get these higher amplitude wave patterns in the jet stream".

The report was the work of three hundred federal and non-federal scientists and experts from across a variety of federal agencies.

The report explicitly criticised the Trump administration agenda of expanding the use of fossil fuels in electricity generation. On Wednesday amid plunging temperatures on the East Coast, he wondered in a tweet: "Whatever happened to global warming?"

Former vice-president and Democratic presidential candidate Gore accused Trump of seeking to "hide the truth" by releasing the report on Black Friday.

Gore was not the only critic questioning the timing of the release.

Friday's report seemed to anticipate such comments, saying: "Over shorter timescales and smaller geographic regions, the influence of natural variability can be larger than the influence of human activity".

The report also reiterated the officials" concerns regarding the "greenhouse effect", the gradual warming of the Earth's atmosphere associated with the anthropogenic generation of carbon dioxide, methane, nitrous oxide and other so-called "greenhouse gasses'.
