At the time of the Geomagnetic Superstorm of May 15th 1921, the Earth’s Global Temperature was – compared to the average [1886-2020] – in negative territory! It stood at a relative value of -0.2C. Yet Solar Cycle 15 was coming off a very active period (see below) and this finale, while unexpected and totally unique in the 20th Century for its intensity, did not even raise the Earth’s Global Temperature 0.01C ! WoW!
There are plenty of myths out there perpetrated by the fossil-fuel interests and other. One myth states that during periods of high sun spots and solar activity, the Earth’s temperature rises independent of humanity. Well, it was -0.2C during the SuperStorm, before and after immense solar activity. In fact, the most intense solar activity of the last century.
This is just another way that they try to discredit Prof. Dr. Michael E. Mann, a National Academy of Science member, and his now-famous “Hockey Stick” of Human-Caused Global Temperature Rise (below).
It’s us. Make no mistake. Humanity is causing the Global Temperature rise. And we can stop it, can’t we?
