The report’s authors, who represent numerous federal agencies, say they are more certain than ever that climate change poses a severe threat to Americans’ health and pocketbooks, as well as to the country’s infrastructure and natural resources. And while it avoids policy recommendations, the report’s sense of urgency and alarm stands in stark contrast to the lack of any apparent plan from President Trump to tackle the problems, which, according to the government he runs, are increasingly dire.
The congressionally mandated document — the first of its kind issued during the Trump administration — details how climate-fueled disasters and other types of worrisome changes are becoming more commonplace throughout the country and how much worse they could become in the absence of efforts to combat global warming.
Already, western mountain ranges are retaining much less snow throughout the year, threatening water supplies below them. Coral reefs in the Caribbean, Hawaii, Florida and the United States’ Pacific territories are experiencing severe bleaching events. Wildfires are devouring ever-larger areas during longer fire seasons. And the country’s sole Arctic state, Alaska, is seeing a staggering rate of warming that has upended its ecosystems, from once ice-clogged coastlines to increasingly thawing permafrost tundras.
