With the release of its National Climate Assessment on Friday, the U.S. government has released a report—which states the current period is “now the warmest in the history of modern civilization”—that critics say directly and irrefutably undermines the climate denialism and inaction of President Donald Trump and his administration.

“Even as this report sounds the alarm, Trump’s team of climate deniers are twisting themselves into pretzels to justify blocking national and international climate action. If America’s leaders don’t start listening to scientists, the whole world is going to pay a truly terrible price.”

Mandated by law and released every four years, the Fourth National Climate Assessment (or NCA4) — which states that recent years have seen “record-breaking, climate-related weather extremes, and the last three years have been the warmest years on record for the globe”— concludes (with emphasis in the original) that “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. For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence.”
