Be it Climate Doomsday, Climate Emergency or Climate Crisis: It's not just a matter of the global warming that has taken place since the late 1800s.
More importantly, it's how much the temperatures are changing over a period of time and the speed at which they are doing so that are the central characteristics determining if the climate is actually headed towards a disequilibrium state of doom.
If the Earth's climate is approaching a disequilibrium, or is already in a disequilibrium of existential climate instability, global temperature change and acceleration rates would have to be unprecedented.
By using the IPCC's gold-standard (HadCrut) of global temperature measurements, it can be determined if the global temperatures at the end of 2020 are exhibiting an amount of change and/or acceleration that are unprecedented.
As these two accompanying charts establish, modern (red) temperature change and the rate at which it has changed are essentially similar at the 20-year mark to the pre-1950 (blue) changes and associated rates of change.
[The 240-month trend rate ending at December 2020 ranks only as the 362nd highest, and the 240-month temperature change ending for December 2020 ranks as the 340th largest, which means that neither are outside the realm of natural climate variability seen before.]
Yet, these similar global climate temperature characteristics for 2020 and 1941 exist despite atmospheric CO2 levels being one-third higher at the end of 2020 versus that of the year-end 1941 level.
And there was not a single, rational politician or responsible journalist of 1941 claiming that the Earth was facing a climate emergency.
The simple truth, based on the scientific empirical evidence: Our modern climate does NOT exhibit the two key characteristics required for an 'unprecedented,' runaway, tipping point global warming of climate change doomsday. And it's not even remotely close to being a possibility.
