None of that matters to what I was pointing out. I was pointing out (1) that the past of the earth had vastly higher co2 than we would have even if we burned all the oil, coal, and natural gas in the ground all at once and (2) that the earth had significantly higher temperatures than what anyone is forecasting as a result of co2 emissions. In case 1, 2, and 1 and 2, plants and animals on land and sea thrived.
So, whether you want to focus on higher co2 or higher temps, or both, my point is that it seems (given history) unlikely that it would endanger animal, plant, land, or sea life on earth.
Off the top of my head (plus review of vid below), and an almost complete bottle of wine, (Francis Coppola. 2013 Claret about $10 or $15 – very good value for money), here’s what I can say.
Yes 400 million years ago C02 levels were high (1,000 – 2,000 ppm). As I said, even at these levels the earth almost turned into a block of ICE. If you think about it, though, the earth was a LOT DIFFERENT back then.
But let’s just move on.
I’ll tell you what, take care of these issues for me and I’ll be OK with most of what you have to say about not worrying about high C02 levels.1) Please cool down the effect of the sun for us. I guess you can hose it down or perhaps push out the earth’s orbit a bit. (I might have an HP 41cv to help you out to figure out how far the orbit will have to go. BTW, you will have to supply the batteries)
2) Push the continents back together. You know, reverse all of that tectonic stuff.
3) Once #2 is done, hammer all of the mountains down flat. I know that this sounds tough but my thoughts are that if you pulled off #2 this shouldn’t be that hard.
4) You got to kill off a bunch of plants. Unfortunately I don’t have a list right now. But I might be able to work out a punch down list by the time you get to this task.
5) Kill off a lot of the animals. (See #4 for issues with list)
6) TBD (
I think that I already posted below before. Real short. Informative;
