The numbers are out, and they are not pretty. Global average temperature in 2020 was 1.25C above the turn-of-the-previous-century average (1880-1910), thus set a new record for the warmest year.
Relative to the year 1750, you need to add 0.3C for the baseline shift, so 2020 was actually 1.55C warmer than 1750, which is termed the real pre-industrial, and the Paris climate agreement in 2015 had numerous countries promise to strive to work together to keep this global average rise, relative to preindustrial (1750) below 2C, with aspirations to stay below 1.5C.
Thus, 2020 blew past the 1.5C number, hitting 1.55C.
What is amazing about this is that is happened in the year of the coronavirus industrial shutdowns, in which global greenhouse gas emissions from burning fossil fuels decreased by about 7%.
Also, 2020 was a weak La Niña year. The effect of this ENSO (El Niño Southern Oscillation) La Niña depressed global temperatures by an estimated 0.1C (my estimate). This, if 2020 was ENSO neutral, the global average temperature would have hit 1.65C. Even worse, if 2020 had been a strong El Niño year, add 0.2C to that temperature (by my estimate). This would have resulted in global average temperature hitting 1.85C higher than 2050, by my best estimate. This will happen, no doubt, in a few short years when we have another powerful El Niño similar to that in 2015-2016 which caused us to have the record setting temperature year that was just broken in 2020.
Climate warming is spiralling out of control. We urgently must deploy my so called three-legged barstool solution triage:
1) Slash fossil fuel emissions.
2) Remove CO2 and methane from the atmosphere/ocean system (CDR).
3) Deploy Solar Radiation Management (SRM) technologies to cool the Earth.
We could quickly do these emergency things by using the 700 to 900 billion $US military budget and defence industry scientists and engineers to work on these last ditch solutions to stabilize climate. Without this, our global food supply will be crushed like a bug within the next 5 to 10 years, causing global strife.
