This is an extremely good, no-nonsense long-term climate & global warming assembly with only 1 huge wart and a little one with something out of date. The so-called "greenhouse effect (GHE)" in Earth's troposphere is described at 6:56 entirely incorrectly as it usually is. GHGs don't re-radiate any photons. They simply convert them into colloquial "heat", so they heat the troposphere instead of going to space. The troposphere is heated by solar SWR, and by rising thermals, water evaporation latent heat & LWI radiation from the surface. Using this heat the GHGs in the troposphere manufacture radiation and some of that radiation emitted at heights below about 900 m makes it to the surface, mostly radiation made by the ghgs in the lowest 100 m is what makes it to the surface. The ghgs manufacture about 200 times as much radiation as the surface but only like 0.4% of that manages to get to the surface and only like 0.3% of that manages to get to the stratosphere. The other thing is that the proxy shown at 28:34 from the 2 published papers in 2012 & 2013 was a good effort but since late 2021 is superseded by the 49 scientist-years of work assembling 524 published proxy analyses Osman et al, Earth globally (GLOBALLY) GMST for 24,000 years ago until 2010 CE is shown at ruclips.net/video/CqtZdnpfgIc/видео.html at 5:55, 6:05 and 7:00.
