Dear Commons Community,
Government scientists agree that, contrary to President Donald Trump and his team’s repeated claims, climate change is already having a dramatic effect in the U.S., according to a new report. An unreleased draft by scientists from 13 federal agencies concludes that Americans are feeling the effects of climate change right now. It directly contradicts claims by President Trump and members of his cabinet who say that the human contribution to climate change is uncertain, and that the ability to predict the effects is limited.
“Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” the draft states. As per the New York Times.
“The 543-page report was written by scientists from 13 federal agencies, including the Environmental Protection Agency and the National Oceanic and Atmospheric Administration. It concludes that temperatures in the U.S. have risen sharply, by 1.6 degrees Fahrenheit, over the last 150 years and that it is “extremely likely that most of the global mean temperature increase since 1951 was caused by human influence on climate.”
“Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” the report states. “Thousands of studies conducted by tens of thousands of scientists around the world have documented changes in surface, atmospheric, and oceanic temperatures; melting glaciers; disappearing snow cover; shrinking sea ice; rising sea level; and an increase in atmospheric water vapor. Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate changes.”
The report, completed this year and part of the National Climate Assessment, has already been approved by the National Academy of Sciences, according to the Times. Its release hinges on the Trump administration’s approval, and one scientist who worked on the report told the Times that he and others feared the president would withhold it.”
