RE:A good read for dummies like stalkhouseYes greenhouse gases act as insulation keeping the earth's average temperature livable. Without them the average global temperature would be minus 18 C where nothing would live because all water would be frozen and nothing would grow ie no food.
So greenhouse gases are good. They're essential for life. But sometimes they reach high concentrations driving up the average temperature. I read that during the Cretaceous when the dinasaurs roamed the planet, it was the most extreme period of global warming. Average temperatures were 4C higher than today. Polar ice caps had melted. Sea levels 80 meters higher than they are today. Yet life thrived. This notion that global warming is gonna kill all life is bs.
For me, there's no doubt that we've passed the tipping point. There's no stopping the positive feedback loops now. Positive feedback means that warming temperatures will dry out ever more vegetation, fires will become more frequent, more CO2 will be emitted into the atmosphere causing even more warming (positive feedback) causing warming to accelerate causing even more fires.
How about those sink holes and lakes popping up out of nowhere in the Arctic where permafrost is melting releasing incredible amounts of methane into the atmosphere which is 32 times more powerful as a greenhouse gas than CO2 is? Talk about positive feedback and past the tipping point.
But hey let's blame it all on CO2. What a bunch of uninformed garbage! How about the millions of tonnes per day of highly toxic, high molecular weight therefore high heat trapping capacity, industrial air contaminants that we spew into the atmosphere?
I do air dispersion modelling. We are past the tipping point. All of what we spew gets trapped into and accumulates in the troposphere because of the temperature inversion in the tropopause between the troposohere and stratosphere. The troposhere is the region of the atmosphere from the earth's surface up to as high as about 15 km. All that we identify as weather occurs in the troposphere and we've polluted the heck out of it. How can the climate not change? Smh
So, grow more trees to take CO2 out of the atmosphere, ban all fossil fuels so as not to introduce any more human created CO2, ger the CO2 levels back down to under 100 ppm and we're still f'd because of all of the other air contaminants that we spew. So get readily for some major disruption to everybody's lives. Geez I'm reading now that Germany is slmost out of ground water, same as in the American midwest, southwest major crop growing areas. Lack of rain. Not for lack of humidity in the atmosphere though. It's simply too hot for the water vapor in the atmosohere to condense into clouds where the rain falls out of.
