What about the people that say "More CO2 => More problems"
It seems that CO2 levels are up 100% over the last couple hundred years. I will let you be the judge of wether or not that has caused any problems. If you have concerns with wether or not CO2 will be up another 100% over the next couple hundred years, maybe it will. But its a slow process and there will be time for most people and most species to adapt if needed. But also it will not be possible for CO2 levels in the atmosphere to double every 200 years. Because the earth is pretty much a closed system. Sometimes the carbon is stored underground, sometimes its stored in the atmosphere, its a cycle.
Can even talk about how central banking and all this debt that is in the world has released epic amounts of CO2 that wouldnt have been possible otherwise. I mean, it leads to increased consumption, demand, etc. we are borrowing from the future to spend in the presents. Therefore human CO2 emissions are likely significantly increased, and will decrease in the future as the economy switches from consuming and spending to just paying off debt one way or the other.
Btw. does anyone want to discuss if the earth is growing or not?
