From CNN today.There has never been a hotter month recorded on Earth than this July. . . . 2015-2019 looks set to be the warmest recorded 5-year period.
There have been hotter months on Earth, but those pre-date contemporaneous recordings of temperatures and are a very, very long time ago, because natural drift in climate conditions is usually much slower on the upside (although ET impacts and volcanos can cause sudden cooling).
