Humans are not creating some new form of the CO2 molecule when burning fossil fuels, which does release CO2 to the atmosphere.
The "man made" CO2 added to the atmosphere was previously in the atmosphere.
And when it was in the atmosphere millions of years ago, that CO2 did not cause runaway global warming!
CO2 in the atmosphere back then was later naturally sequestered as carbon in coal, oil, natural gas, and limestone, many millions of years ago.
Humans 'dig up' and burn huge quantities of fossil carbon.
The climate zealots freak out, and claim adding CO2 back into the air will cause runaway global warming.
They seem to have no idea that the CO2 was in the air millions of years ago!
And our planet had no runaway warming back then.
That's why we know putting some of the CO2 back into the air will not cause runaway warming!
There is no actual science to back up the scary claim of runaway global warming from humans adding CO2 back into the air!
I repeat for emphasis: No actual science supports the fantasy of runaway global warming, it's just a wild guess theory that makes no sense!
Almost all of the 4.5 billion year history of our planet included more CO2 in the air than today, according to geologists.
Based on ice core proxy studies, CO2 levels were at their lowest level ever about 20,000 years ago (at about 180 parts per million, or ppm)
Most of the plants that humans and farm animals eat would have stunted growth at 180 ppm, and most would not survive if CO2 levels fell below 150 ppm.
Humans are blamed for increasing the CO2 level from 275 ppm in 1750 (ice core proxy estimates), to 400 ppm today (Mauna Loa real time measurements).
Most of that CO2 increase is claimed to be man made.
I have no reason to debate the unprovable claim that humans caused a +100 ppm CO2 increase, from 300 ppm in 1910 to 400 ppm in 2017, because I consider that to be good news for our planet.
The atmospheric CO2 increase in the past 20,000 years was from 180 ppm to 400 ppm.
Huge glaciers melted from natural causes, and sea level rose 400 feet.
That CO2 rise was just in time to keep green plants growing -- and that fact almost makes this long time atheist believe in miracles!
Based on real science, not the usual climate change hysteria, I want humans to keep increasing the CO2 level to the 800 ppm to 1,200 ppm level that would promote maximum green plant growth.
Greenhouse owners already enrich greenhouse CO2 levels, from 400 ppm to about 1,000 ppm, to accelerate plant growth, and they are certainly experts at growing plants.
