I am kinda guessing that the change in ocean temps has more to do with this than anything else. The huge spike in temps during the early 1800's is having an effect. I just didn't know that cars, coal fire power plants and the cutting down of rain forest had an impact that long ago. Dang, it happened quickly. http://math.ucr.edu/home/baez/temperature/temperature.html#1.35Myr View attachment 10654 http://www.ace.mmu.ac.uk/Resources/gcc/5-3-1.html View attachment 10655
Humans can build more gasoline refineries and humans can effect border control so let's concentrate on those things and not waste time and energy on a "problem" that humans can do nothing about. We could all live like the cavemen did and the planet is still gonna do what it's gonna do.
We CAN do some things about it. Have you noticed the pollution that man has caused? We can do something about that, too and we already have. Our impact on this planet is significant and what we can do, we can undo. The notion that man is helpless in the face of nature is absurd, mon ami.
How can you really beleive this. Look at the profound impact the nutria has had on the ecosystems of SE Louisiana. Don't you think we have a greater ability to impact our environment than those tasty little devils.
Not my point. The planet will correct itself with or without us. I imagine if you could look at a globe of the World at the beginning and compare it to a globe depicting the day before humans appeared, you would see significant changes in land masses. Our impact is on other humans. The planet laughs at our insignificant selves.
