NASA Date shows that September was the hottest on record.

Just like August, September was the hottest on record globally (according to NASA). NOAA maintains a different record, and will report their number any day now. The data sets use slightly different methods, but it’s a good bet that they will show a new record as well. NASA also has a graph showing the heat anomalies by latitude:

As has long been the case, the high latitudes are showing most of the warming. This is what would be expected with warming due to greenhouse gases.

NOAA’s National Climate Data Center created a very good info graphic that shows why we may very well be on the way to the hottest year on record globally. The graphic was done in August before we broke the September record, so a new record hottest year is now even more likely. See image below:
