The New England Patriots are finalizing a contract extension with quarterback Tom Brady, a league source told ESPN's Field Yates.

Brady would have become an unrestricted free agent after the 2019 season. He is set to make $14 million this season.

News of the extension comes a day after Brady celebrated his 42nd birthday.

Secretary-General Antonio Guterres says the latest data from the World Meteorological Organization shows that the month of July "at least equalled if not surpassed the hottest month in recorded history" — and it followed the hottest June ever.

The UN chief told reporters Thursday that "this is even more significant because the previous hottest month, July 2016, occurred during one of the strongest El Niño's ever," which was not the case this year.

Guterres said this means the world is on track for the period from 2015 to 2019 "to be the five hottest years on record."

He warned that if all nations don't take action now to tackle climate change and global warming, extreme weather events happening now will be "just the tip of the iceberg."
