Given the total irrelevance of volcanic aerosols during the period in question, the only very modest effect of fossil fuel emissions and the many inconsistencies governing the data pertaining to solar irradiance, it seems clear that climate science has no meaningful explanation for the considerable warming trend we see in the earlier part of the 20th century — and if that's the case, then there is no reason to assume that the warming we see in the latter part of that century could not also be due to either some as yet unknown natural force, or perhaps simply random drift.

Agree with Mr. Richards (31) that a «budget» for 1.5 C has already been exceeded — due e.g. to «thermal response factor» (Hansen), present aerosol dimming, further emissions during energy transition, unfolding climate feedbacks and planetary response to actual total carbon dioxide eguivalent.

I am not sure I get how you arrived at this: «During this period, anthropogenic CO2 emissions amounted to about 20 % of the total CO2 emissions» I suspect you may be forgetting that the emissions are cumulative, so even a flat blue line would go with a rising orange one.

Emissions of ODS gases (also GHGs) controlled under the Montreal Protocol (CFCs, HCFCs) increased from a very low amount during the 1950 — 1960s to a substantial percentage — approximately 20 % — of total GHG emissionsEmissions of ODS gases (also GHGs) controlled under the Montreal Protocol (CFCs, HCFCs) increased from a very low amount during the 1950 — 1960s to a substantial percentage — approximately 20 % — of total GHG emissionsemissions by 1975.
