The Trump administration has released a report that concludes climate change is real, almost exclusively caused by human activity and could have devastating consequences for the U.S. The report's findings contradict the public statements and environmental policies made by President Donald Trump and Environmental Protection Agency Administrator Scott Pruitt.
On Nov. 3, the Trump administration released its National Climate Assessment, a report that has been mandated by law since 1990. The assessment found that global temperatures had risen by 1.8 degrees Fahrenheit since 1900 and warned that sea levels could rise by 8 feet by 2100, The Washington Post reports.
"It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century," the report stated. "For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence."
The assessment warned that the escalation of global temperatures was unprecedented, stating "there is no climate analog for this century at any time in at least the last 50 million years."
"The global climate is projected to continue to change over this century and beyond," the report continued. "The magnitude of climate change beyond the next few decades will depend primarily on the amount of greenhouse (heat-trapping) gases emitted globally and on the remaining uncertainty in the sensitivity of Earth's climate to those emissions."
The assessment was compiled by 13 separate federal agencies and was approved by the Trump White House. The report's findings clash with the Trump administration's policy decisions, such as pulling the U.S. out of the Paris climate agreement and working to rescind greenhouse gas regulations.
Trump has been a vocal climate skeptic. In November 2012, he took to social media to assert that climate change was a hoax invented by the Chinese government.
"The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive," Trump tweeted.
On March 10, Pruitt stated during an interview that he did not believe human activity contributed to rising global temperatures.
"I think that measuring with precision human activity on the climate is something very challenging to do and there's tremendous disagreement about the degree of impact, so no, I would not agree that it's a primary contributor to the global warming that we see," Pruitt told CNBC.
Woods Hole Research Center director Phil Duffy noted that the National Climate Assessment directly contradicted the Trump administration's posture towards climate change.
"This is a federal government report whose contents completely undercut their policies, completely undercut the statements made by senior members of their administration," Duffy said.
"It begs the question, where are members of the administration getting their information from?" Duffy told The New York Times in a separate interview. "They're obviously not getting it from their own scientists."
Senior fellow Marlo Lewis Jr. of the Competitive Enterprise Institute asserted that the report's findings did not mean that the Trump administration's policies were misguided.
"To me the real issue is, where do the risks lie?" Lewis said. "Suppressing your economy is never a good solution."
