Liberal elites need to drop the pretenses - they want to ban all conservative speech...

One MAJOR volcanic eruption spews more vapor and other "greenhouse gases" into the atmosphere than MAN HAS PRODUCED SINCE MAN HAS BEEN ON THE PLANET!

Not even close. Pinatubo released 42 Mt of CO2 and mankind releases 7100 Mt every year.

However solar activity is slow right now and because of leftover ocean warming (especially in the Arctic) there is a lag in cooling. If the coming cooling (strong likelihood) could be solved by one volcano worth of GHG that would be great, but unfortunately not even close to correct. For one thing, CO2 is a weak GHG. If you count the water vapor from volcanoes that would also be incorrect in two ways: water vapor is transient, and human-produced water vapor also greatly exceeds volcanic water vapor.

One more note about vapor. You are correct that water vapor is the most important GHG and there is a lot of it: about 500,000,000,000,000 Mt from evaporation and transpiration. In contrast, Pinatubo released 500 Mt. Mankind is probably in the 10's of thousands of Mt per year. None of our water vapor matters, it is too trivial. Likewise volcanic water vapor.

All that matters is weather, i.e. the distribution of water vapor. Not even the amount matters, but how even or uneven the water vapor is. For example if there is more "extreme weather" (a popular buzz phrase with no basis in reality) there will be global cooling.

Thank you for that IPCC data.

And BEFORE the advent of internal combustion engines and other fossil fuel consuming devices, the streets of cities and villages across the globe were ankle deep in animal waste and the source of the diseases that killed millions.

Thank you, but I’ll trade the the mythical chance that climate change (or whateverthehell they decide to call it next week) for not having to live in pre-1900 conditions!
