The Trump administration released a dire scientific report
Friday detailing the growing threats of climate change. The report
stands in stark contrast to the administration’s efforts to downplay
humans’ role in global warming, withdraw from an international climate
accord and reverse Obama-era policies aimed at curbing U.S.
greenhouse-gas output.
The White House did not seek to prevent the release of the government’s National Climate Assessment, which is mandated by law, despite the fact that its findings sharply contradict the administration’s policies. The report affirms that climate change is driven almost entirely by human action, warns of potential sea-level rise as high as eight feet by the year 2100, and enumerates climate-related damage across the United States that is already occurring as a result of 1.8 degrees Fahrenheit of global warming since 1900.
“It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century,” the document reports. “For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence.”
The report’s release underscores the extent to which the machinery of the federal scientific establishment, operating in multiple agencies across the government, continues to grind on even as top administration officials have minimized or disparaged its findings. Federal scientists have continued to author papers and issue reports on climate change, for example, even as political appointees have altered the wording of news releases or blocked civil servants from speaking about their conclusions in public forums. The climate assessment process is dictated by a 1990 law that Democratic and Republican administrations have followed.
The report comes as Trump and members of his Cabinet are working to promote U.S. fossil-fuel production and repeal several federal rules aimed at curbing the nation’s carbon output, including ones limiting greenhouse-gas emissions from existing power plants, oil and gas operations on federal land and carbon emissions from cars and trucks. Trump has also announced he will exit the Paris climate agreement, under which the United States has pledged to cut its overall greenhouse-gas emissions between 26 percent and 28 percent compared with 2005 levels by 2025.
With high levels of warming, coastal property damage in 2090 could total $120 billion annually, and deaths from temperature extremes could reach 9,300 per year, or in monetized terms, $140 billion annually in damage. Additional tens of billions annually could occur in the form of damage to roads, rail lines and electrical infrastructure, the report finds.
This could all be lessened considerably, the report notes, if warming is held to lower levels.
