Hot, hot, hot

This is actually getting a little scary:

This was not just another of the drumbeat of 10 straight broken monthly global heat records, triggered by a super El Nino and man-made global warming. February 2016 obliterated old marks by such a margin that it was the most above-normal month since meteorologists started keeping track in 1880, according to the National Oceanic and Atmospheric Administration.

The old record was set just last December and the last three months have been the most above-normal months on record, said NOAA climate scientist Jessica Blunden. And it’s not just NOAA. NASA, which uses different statistical techniques, as well as a University of Alabama Huntsville team and the private Remote Sensing System team, which measure using satellites, also said February 2016 had the biggest departure from normal on record.

2014 was the warmest year on record, until last year easily beat that record. If you look at the data from NASA here (go here for the site) you will notice that there was no month that was more than 1 degree Celsius above the mean for that month until October 2015, but each of the months since then have been above that threshold. Any one month or any one year doesn’t tell us much, so let’s look at the records since 1880:

If you don’t see an upward pattern in the last 40 or 50 years you must be willfully blind.

We don’t have to rely on NASA, here’s the NOAA (the full report is here):

  • The year-to-date temperature across global land and ocean surfaces was 2.03°F (1.13°C) above the 20th century average. This was the highest for January–February in the 1880–2016 record, surpassing the previous record set in 2015 by 0.52°F (0.29°C). January and February were both record warm for their respective months.
  • The year-to-date globally-averaged land surface temperature was the highest for January–February in the 1880–2016 record at 3.51°F (1.95°C) above the 20th century average. This was the highest for January–February in the 1880–2016 record, surpassing the previous record of 2002 by 0.74°F (0.41°C).
  • The year-to-date globally-averaged sea surface temperature was 1.49°F (0.83°C) above the 20th century average and the highest for January–February in the 1880–2016 record. This was the highest for January–February in the 1880–2016 record, surpassing the previous record of 2010 by 0.40°F (0.22°C).

By the way, the fact that the land is warming more than the ocean is one of the signatures showing the driver of the warming is human based. You can see a class on Global Warming starting here.
