NOOA says the combined greenhouse gases released by mankind has reached a warming factor equivalent to 504ppm of CO2.
NOAA warns that the IPCC says a level of 550ppm CO2 would heat the earth by 3C, which is well past disastrous for many nations.
Without wanting to alarm anyone, this is alarming.
And there has been no great greenhouse gas slowdown from the COVID pandemic.
