The federal government released a lengthy report on climate change Friday warning that urgent action must be taken to stop increasing climate-fueled disasters like the wildfires in California, directly contradicting President Trump’s repeated dismissals of global warming as a cause for concern. The National Climate Assessment’s report, the first of its kind under Trump, was written by experts at numerous federal agencies and consists of more than 1,000 pages of findings. The authors argue that humans need to fight climate change aggressively now in order “to avoid substantial damages to the U.S. economy, environment, and human health and well-being over the coming decades.” The congressionally mandated report also directly links severe weather-related catastrophes like the raging wildfires in California to global warming, despite Trump’s assertion earlier this month that “mismanagement” of forest land was to blame. The report warns that “the evidence of human-caused climate change is overwhelming and continues to strengthen, that the impacts of climate change are intensifying across the country, and that climate-related threats to Americans' physical, social, and economic well-being are rising.”
