afaict, the situation can be roughly summarized as : - global climate is warming by around +0.3C per decade - its caused mainly by humans burning carbon chains for energy, emitting CO2 - we are currently sailing thru +1.5C above pre-industrial mean temp - Methane CH4 is also a strong warming agent, around 20x more potent than CO2, on decade timescales - humans are emitting all time high levels of C02, around 40Gtonnes / yr - Carbon capture / CCS / DAC need to be millions of times more efficient to be significant - we dont have enough room or time to plant trees to remove the CO2 - net-zero when we reach it, corresponds to max-Co2 which means peak-heat - net-zero aka peak-heat might occur bu 2060, by which time we'll be near +2.5C - extreme events are not linear in increase in temp [ think of shifting the mean of a bell curve ] Even if we do a great job of electrifying everything, moving away from fossil/carbon fuels by 2060, we still have a heat problem to deal with - will we be able to grow our normal crops under +2.5C, and deal with extreme heatwaves, floods, storms ? It seems we will need Solar Radiation Management Geo-engineering "SRM" in order to survive that peak-heat and buy us a few decades in which to slowly remove CO2 [ even as we move full steam ahead to de-carbonize our energy system with wind, solar, battery packs, hydro, fission, geothermal and hopefully fusion power ] Particulates from volcanoes are well known to cause a cooling effect, and its now becoming more obvious that particulates in pollution in Asia, and sulphur impurities in shipping fuels were having a measurable cooling effect - we seem to be warming faster now that Asia and shipping fuels are not producing as much particulate pollution [ thus less cooling effect ] It seems to me the only "Hail Mary" we have to address the heat problem, is to use SRM to exert a cooling effect - we humans geo-engineered a warm planet over 150 years of burning carbon fuels, and we will need to geo-engineer our way out of this mess. tldr : Abundant clean energy is needed, but we also have to address the heat problem - with SRM geo-engineering
