I’m taking you to an early picture of Guy McPherson because the lecture he did seven years ago. I even did my first blog on the work of Guy McPherson as a result of this lecture. It linkS to a Youtube video of his lecture:
One of the factoids that stuck with me was early in this lecture. Guy calls up a late 19th century Swedish chemist Svante Arrhenius. He was famous for nearly calling a prediction that global warming would be one full degree C by the year 2000. He was really close on this–he was off by .2 C, and you could make a case that between the Great Depression of the 1930’s and WWII, the increase in temperature was called correctly. So….8 C in 100 years. A landmark determination, eh?
Latest news from Sam Carana who’ve I’ve quoted before.
From Sam Carana’s own text:
POTENTIAL TEMPERATURE RISE FROM PRE-INDUSTRIAL TO 2026
We face the threat of a potential temperature rise from pre-industrial to 2026 of 18.43°C and the eventual disappearance of all life from Earth.
NASA data shows a 1920-2020 temperature rise of 1.29°C. To calculate the rise from pre-industrial, 0.29°C is added for the 3480 BC-1520 rise, 0.2°C for 1520-1750 and 0.3°C for 1750-1920, while 0.1°C is added to reflect higher polar anomalies and 0.1°C for air temperatures, adding up to a rise of 2.28°C from pre-industrial.
A temperature rise of a further 16.15°C could happen by 2026, adding up to a total potential temperature rise of 18.43°C from pre-industrial to 2026.
Most species will likely go extinct with a 5°C rise, but humans will likely go extinct with a 3°C rise and eventually, all life would disappear from Earth, as discussed earlier in the post ‘Most Important Message Ever’
