September was hot — really hot.

Depending on who you ask, it was the hottest or second hottest September ever recorded.

The confusion stems from the fact that, while NASA and NOAA use the same exact raw temperature data, they each analyze it a little differently (you can read more about it here).

NOAA’s finding officially ends an unprecedented 16-month-long streak of record-breaking temperatures. There is now a greater than 99 percent chance that 2016 will end up being the hottest year we’ve ever seen. Ever.
