It is widely publicized that 2016 will certainly break the record for yearly average global temperature. Again. This will be the third year in a row we’ve set a new record. It’s time we paid attention.
I’ve often emphasized that just because Earth shows an indisputable warming trend, that doesn’t mean every year will be hotter than the one before. In addition to trend, there is also a lot of fluctuation in things like global temperature. So we shouldn’t expect each year to break the temperature record.
But we did in 2014. We did again in 2015, by a substantial margin. We did again in 2016, by a substantial margin. The third year in a row of record-breaking global temperature will probably get the most attention, but it may not be the most important or most worrisome record set last year.
Ever since NOAA released their latest update to sea surface temperature, version ER-SSTv4 (Extended Reconstruction Sea Surface Temperature version 4), it — and they — have been the target of vicious attack. It has come not just from climate denier bloggers, but from politicians like Lamar Smith (R-TX, chairman of the House committee on Science, Space, and Technology). The accusations haven’t been limited to error, rather they have focused on claims of outright fraud by NOAA scientists, saying, without any justification whatever, that the new version was an attempt to deceive, simply because it shows faster recent warming than other versions.
But new research has not only vindicated them, it establishes that their latest update shows every sign of being the best sea surface temperature data set yet. As in, the best.
Tony Heller has replied to my previous post. I don’t think he likes me very much.
How would we expect global warming to affect the world’s amount of snow cover?
The useful thing about a canary in a coal mine is that it warns you of danger before the danger kills you.
When 2016 began last January 1st, the average temperature throughout the Arctic was fully 18°F (10°C) hotter than usual for New Year’s day, and the extent of sea ice in the Arctic was lower than ever before recorded for that date:
The extra-high temperatures and extra-low sea ice with which the Arctic started the year, was just the beginning.
We’ve been observing sea level with satellites for 24 years now.
