Good morning.

Here’s what you need to know:

• An alarming climate report.

The average temperature in the U.S. has risen drastically since 1980, according to a draft report by scientists from 13 federal agencies.

The report, obtained by The Times, concludes that Americans are already feeling the effects of climate change. That contradicts claims by President Trump’s administration, whose approval is required for the document to be released officially. You can read it here.

“It’s a fraught situation,” a professor who was not involved in the study told us. “This is the first case in which an analysis of climate change of this scope has come up in the Trump administration, and scientists will be watching very carefully to see how they handle it.”
