A U.S. government report says the impacts of climate change, including powerful storms, droughts and wildfires, are worsening in the United States.
The report, written with the help of more than a dozen U.S. government agencies and departments, frequently contradicts the statements and policies of U.S. President Donald Trump.
The congressionally mandated report was quietly issued Friday during a holiday weekend. The White House later dismissed the report as inaccurate, according to a Reuters report.
White House spokeswoman Lindsay Walters told Reuters Friday the report was “largely based on the most extreme scenario, which contradicts long-established trends by assuming that…there would be limited technology and innovation, and a rapidly expanding population.”
The National Climate Assessment, totaling more than 1,000 pages, warned of more powerful and longer weather disasters triggered at least, in part, by global warming.
It said such weather disasters are becoming more commonplace around the country and warned that without aggressive action they could become much worse.
While the report avoids policy recommendations, it said humans must take measures to stop future weather disasters “to avoid substantial damages to the U.S. economy, environment, and human health and well-being over the coming decades.”
“Future risks from climate change depend primarily on decisions made today,” the report said.
It predicted that climate change will cost the U.S. economy hundreds of billions of dollars by the end of the century if no efforts are made to curb its effects and said global warming would disproportionately hurt the poor.
This year’s National Climate Assessment is the fourth time the U.S. government has issued a comprehensive look at climate change and is the first assessment to take place during the Trump administration. The last report came in 2014.
11 Thirteen government departments and agencies, including the Department of Agriculture and the National Aeronautics and Space Administration (NASA), were part of a committee of more than 300 researchers who compiled the assessment.
Several people involved in the report told The Washington Post that its release originally had been planned for early December. However, they said after a behind-the-scenes debate about when to make it public, administration officials settled on the Friday after Thanksgiving, traditionally one of the slowest news days of the year.
During a press conference Friday, authors of the report said there had been “no external interference” in the assessment. Report director David Reidmiller said questions about the timing of the release were “relevant,” but said the contents of the report were more important.
The Trump administration has rolled back several environmental regulations put in place during former President Barack Obama’s administration and has promoted the production of fossil fuels.
Last year, Trump announced his intention to withdraw the United States from the 2015 Paris Agreement, which had been signed by nearly 200 nations to combat climate change. He argued the agreement would hurt the U.S. economy and said there is little evidence in its environmental benefit.
Trump, as well as several members of his Cabinet, have also cast doubt on the science of climate change, saying the causes of global warming are not yet settled.
Friday’s report cites other climate studies, which say that humans have caused more than 90 percent of the current global warming. (VOA)
