"Future risks from climate change depend primarily on decisions made today", it added.
The report links heat waves, wildfires, hurricanes, flooding, droughts, crop failures, and damage to infrastructure that has already affected US communities to climate change, and says that "to avoid substantial damages to the USA economy, environment, and human health and well-being over the coming decades", people must take aggressive steps to mitigate climate effects and adapt to those that are already inevitable.
However, the White House has countered the report, calling it inaccurate.
Mr Trump said outside the White House on Monday that he had seen the report and "read some of it".
Since becoming president in 2016, he has pulled the United States out of the worldwide Paris Agreement on attempting to bring down global temperatures, and torn up a raft of environmental protection laws, saying the U.S. economy needs the boost.
The U.S. president rejected the findings of the report, which was produced by over 300 prominent climate scientists and 13 federal agencies and departments. However, several said the timing of its release, at 2 p.m. the day after Thanksgiving, appeared created to minimize its public impact. Weather-related damage has cost almost $400 billion since 2015, The Associated Press reported.
"Warming temperatures are increasing a lot of stress on our ecosystems".
The report, which is mandated by law every few years, is based on more than 1,000 previous research studies. It also finds that global warming could shrink the US economy by as much as 10 percent by the end of the century.
Despite the report, there is no indication that the Trump administration will alter its policies.
Last year, Trump announced his intent to withdraw the United States from the 2015 Paris deal to combat climate change, becoming the first country of 200 to do so. The report's authors conclude that the changing climate 'is transforming where and how we live and presents growing challenges to human health and quality of life, the economy, and the natural systems that support us.' And that, unless we change our practices and policies, there will be 'substantial damages to the USA economy, environment, and human health and well-being over the coming decades'. However, ACE has largely been attacked by coastal states as a weaker plan since it allows individual state the latitude to write their own rules on emissions from coal- fired plants.
