March 2022 temperature anomaly The NASA image below shows the March 2022 temperature anomaly. The Arctic is heating up strongly.  The above image shows a temperature rise for March 2022 of 1.06°C, which is the rise from 1951-1980. The image below shows a temperature rise from 1900 for March 2022 of 1.36°C.  [ click on images to enlarge ] The box on above image shows that, when including further adjustment, the temperature rise from pre-industrial to March 2022 could be as much as 2.35°C. Details of the adjustment are described at the  pre-industrial page . A 2.35°C rise is only 0.65°C away from a 3°C rise and, as described before , a 3°C rise will likely drive humans (and many other species) into extinction.  Note that the March 2022 temperature is suppressed, as we're currently in the depth of a persistent La Niña, as illustrated by the NOAA image on the right.  [ click on images to enlarge ] The above NOAA image shows that the difference be...

Temperatures keep rising. Above image uses NASA data that are adjusted to reflect a 1750 baseline, ocean air temperatures and higher polar anomalies, while showing anomalies going back to September 2011, adding a blue trend going back to 1880 and a red trend going back to September 2011.  The map below also shows that in November 2020, especially the Arctic Ocean, again was very hot. Anomalies in the above NASA image are compared to 1951-1980, while NOAA's default baseline for temperature anomalies is the 20th century average. In the Copernicus image below anomalies are compared to the 1981-2010 average.  Using a different baseline can make a lot of difference. An earlier analysis  pointed out that, when using a 1750 baseline and when using ocean air temperatures and higher Arctic anomalies, we did already cross  2°C above pre-industrial in February 2020.   Above Copernicus image shows temperatures averaged over the twelve-month period from December 2019 ...
