Hain't posted in a bit. Thanks for your patience. The change of the seasons does drive me to much labor, as the onset of the rains hereabouts prompts many malingerers to loudly lament the state of their sieves...er, roofs. Obviously this enables me to ignore everything at the drop of a hat and industriously serve the myriad centers of the universe these folks reckon they are without surcease or days off. But, methinks I doth complain too much, as I quite enjoy it. Nonetheless, it keeps me busy, without days off.
Anyway, I have just done some digging into evolution of life, and provide this for your edification.
The Carboniferous stripped the atmosphere of CO2 and essentially committed suicide, because the innovation of lignin that enabled trees to stand tall was not something detritivores had evolved to process, and this left all that delicious carbon trapped in the corpses of early trees, which became coal after a bit of geological processing.
When massive vulcanism dumped a bunch of light reflecting sulphur into the atmosphere, global temperatures plunged, and terrible conditions for tropical and temperate plants ensued - an ice age - leading lots of herbivores to starve, and so on and so forth.
These corpses of trees didn't only plunge the Earth into massive extinction once, but seem to have done it again at the end of the Permian, when the ~1m year long eruption of the Siberian Traps vulcanism seems to have set the coal seams on fire, releasing something like 170k GtC (170,000 Gigatons of Carbon) into the atmosphere, along with all the mercury necessary to make life impossible for the vast majority of creatures on the planet.
The above video is ~an hour long, so to avoid the details of the research cut to the end and the summary the presenter provides.
The Siberian Traps alone released more CO2 than humans ever will (we have released less than 1% of that amount in all of history), and without any filtering of heavy metals or soot, which we already are dramatically reducing in our emissions. The atmosphere seems to have been flooded with 30x the CO2 it presently holds. The presenter notes that anoxia (lack of O2) and heavy metals pollution - not runaway greenhouse warming - was the cause of the most catastrophic global extinction event Earth has experienced.
These are not events AGW alarmists are interested in discussing, because no one predicts we are going to produce that much mercury and CO2. We never will. We just can't. Long before the CO2 and acidification of the oceans were anywhere near modern levels, living things came back, including reef building organisms. Our atmosphere has lost CO2 ever since, until it bounced off ~190ppm during the LGM (Late Glacial Maximum). Below that, the lowest CO2 level recorded in the fossil record Earth keeps, almost all plants become unable to photosynthesis and starve to death, and this has very bad implications for everything that depends on photosynthetic plants for their own sustenance. If CO2 drops below that almost all life on Earth will die, leaving only chemosynthetic life, those weird deep sea ocean vent ecosystems, left.
We don't want to overproduce CO2 like the Siberian Traps did, but we sure want to release a lot more CO2 into the atmosphere than we presently have, because CO2 ~ten times extant levels enables far higher plant productivity and creates vastly improved living conditions for temperate and tropical living things.
AGW alarmists call CO2 pollution, and fail to recognize it as the essential nutrient that makes life possible. These videos simply prove them wrong, and that all the draconian predictions they make are false. The totalitarian politics they claim are necessary aren't. The blocking of insolation (sunshine) being undertaken is absolutely harmful to all living things, the exact opposite of what we need to do globally.
We barely avoided the worst global extinction event the world could experience a mere ~20kya, and only global warming at the end of the ice age that released CO2 from the oceans allowed us to survive to begin releasing CO2 trapped in mineral deposits, returning it to our global ecosystems that depend on it to survive.
AGW alarmists claim current climate changes are unprecedented. That's completely false, as these videos prove. What we are seeing today is quite mild. They claim it's completely human caused, and that's clearly false, because humans didn't even exist during these events, and haven't produced even 1% of the CO2 one big volcanic event did in all of human history. Every claim they make is false, and all the policies they propose are actually harmful to living things on Earth.
Interestingly, the AGW environmental movement is largely funded by Big Oil. Why would the banksters that own oil, pharmaceutical, and media corporations work together to push these lies? I can only note that if the atmosphere doesn't contain enough CO2 for natural ecosystems to survive, everyone in the world will depend on agriculture controlled by folks that control the supply of carbon. We see the push for carbon credits as the policy that will save the world according to the propaganda.
Carbon credits appear to be the chosen method of gaining ownership of CO2, upon which all life depends. We should fight against carbon credit legislation as if our lives depend on defeating it, because it does.
