A landmark federal government report has found the average temperature in the U.S. has risen dramatically since 1980 and that the impacts of climate change are already being felt across the country. The New York Times obtained and published a copy of the report Monday, amid concerns from scientists that the study’s findings may be suppressed, changed or censored by the Trump administration, which has sought to deny the effects and human impacts of climate change. The report was conducted by scientists from 13 federal agencies. It is awaiting the Trump administration’s approval before it can be officially released. It concludes, “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans.” It also conclusively states that human activities, particularly the emission of greenhouse gases, are the primary drivers of climate change.
