This morning, NASA released its expected press release on the global average temperatures for 2015: “NASA, NOAA Analyses Reveal Record-Shattering Global Warm Temperatures in 2015”. The NOAA issued its own report.

“The globally averaged temperature over land and ocean surfaces for 2015 was the highest among all years since record keeping began in 1880. During the final month, the December combined global land and ocean average surface temperature was the highest on record for any month in the 136-year record.”

As you might have read, the previous record-holder was 2014.

A few days earlier, independent climate change study group Berkeley Earth released the same news: “2015 was unambiguously the hottest year on record.”

A week earlier, the Daily Mail (UK) headlined that 2015 was the third hottest year on record, but clarified in the story that this is based only on satellite temperatures. The story, quite a ways down, confirms “the US National Oceanic and Atmospheric Administration (NOAA) showed 2015 to be the hottest year on record” and actually lists the temperatures that say this is so, from land- and sea-based readings.

(Those who deny anthropogenic global warming, bereft of valid criticism, now try to cling to recent reports that satellite data shows less warming than ground-based thermometers, despite there being no evidence that satellite measurements are more accurate than ground-based thermometers. In fact, there is at least some evidence that the satellite measurements are faulty.)

15 of the 16 warmest years on record have been in the 21st Century (1998 being the other one).

Further, 2015 won the title by the largest margin ever, according to NASA.

In the U.S., 2015 was the second-warmest year on record.

“As for the United States, NOAA released that data last week, saying that for the 19th consecutive year, the annual average temperature for the continental U.S. was hotter than the 20th century average. The agency reported, ‘The last year with a below-average temperature was 1996.’ ”

      Thanks, Richard. With both my last host and this new one, I had trouble figuring out how to keep that email address working, so I’ve just stuck with my old gmail address (and a similar Yahoo! address as a backup).
