An article by Fiona Harvey, Environment Correspondent, appeared in The Guardian two days ago. It underwent a Headline Change.
Seemorerocks has more on this.
The Paris Temperature goal is to keep global warming below 1.5°C and obviously every little Covid CO2 emission drop will help.
Global average temperature is considered by the IPCC to have reached one degree centigrade above Pre-Industrial by the end of 2017. A steady rise of 0.0217°C per year will take us to 1.5 degrees above P-I in 2040. At the end of the first quarter of this meteorological year the global average is notionally 1.07066°C above P-I. There are a lot of numbers in the Ten Station Table below but the “bottom line” is:-
My five northern hemisphere stations have collectively warmed 42 times faster than the IPCC 2017 projection, and the five southern stations have cooled by 3 IPCC units.
The progress of the hemispheres from the beginning of December 2020 is shown below.
Clearly, we need Covid-21, -23, -25 etc if we are not to fry. A cool southern hemisphere is not going to cut the mustard.
