   Excellent 18-minute explainer video on how the greenhouse effect works, and why we know CO2 pollution is the primary driver behind the warming we’ve observed over the past 100+ years -

     @Heil_Honkler @Marshall1Banana When a massive volcano eruption happens, global temperatures don’t rise, they drop, because the soot that has been thrown high into the atmosphere blocks more energy than is captured through slightly higher CO2 concentrations.

     This, by the way, is why about a quarter of climate papers from the 1970s when the field was still young were predicting temperatures would drop, not rise, because some scientists believed the cooling effect from the aerosols we were putting out would outweigh the warming from CO2 increasing the strength of the greenhouse effect.

     @dave @Marshall1Banana Actually the inverse happened when Mount Tambora went off.

     @Heil_Honkler @Marshall1Banana Nope, you have once again fallen for a fake stat. Volcanoes put out around half a billion tons of CO2 annually (on average, obviously). We are currently putting out about 30 billion tons.

     @dave I know it may be my libertarian priors speaking, but wouldn't it make more sense then to find another industrial alternative to resolving the problem of methane and CO2 pollution then, like capturing and using it?
     
     I'm so hesitant to immediately go to zero-CO2 as an individual mandate specifically because it's seems like a top-down policy where people are asked to go without or simply have lower standards of living imposed upon them by governing bodies and institutions rather than innovate an effective solution

     @Marshall1Banana @dave CO2 is a fuckin scam cause volcanos erupting put out like decades worth of what would be collective annual worldwide output of emissions caused by humans and yet you don't see the world turning into an easy bake.

     @Marshall1Banana Yes, and rates of plant growth have increased due to higher CO2 concentrations, and they would help bring CO2 back down to pre-industrial levels. Note that it’s not linear though, and it’s going to take a loooong time for the CO2 to get taken out of the atmosphere naturally, which is why for a zero-CO2 scenario our future temp average forecast is relatively flat.

     Note that for the zero-GHG scenario we do actually see a drop initially, but that’s going to be primarily because of methane, which has a 12 year half-life roughly when in it’s in the atmosphere.

     @dave Ok so the radiation escapes from higher up and the heat further down on the atmosphere goes up to compensate. I get that the phenomenon is real, but wouldn't the added heat promote vegetative growth and through photosynthesis- use up that CO2 over time and bring down overall levels? Even if the CO2 is kept at the outer bounds of the atmosphere- the additional Oxygen produced by said plants would also equalize the gas levels at those outer extremities too?
