A major federal report published by 13 agencies Friday names humans as the primary cause of global climate change.
"This assessment concludes, based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century," the document says. "For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence."
This runs afoul of the Trump administration's stance on the subject. A White House response highlighted a line in the report about "remaining uncertainty," noted "the climate has changed and is always changing," and promoted access to "affordable and reliable energy needed to grow economically."
