General Discussion
In reply to the discussion: I am a Climate Change (human caused) agnostic. [View all]AverageJoe90
(10,745 posts)I personally, after months and months of research, have come to the conclusion that certain human activities are contributing to, and/or even causing, at least a very significant portion, if not the majority, of today's climate change; over 90% of scientists agree on this, as far as I know.
However, though, I also disagree with the "Climate Cassandras" out there. Here's just a few reasons why:
1.)The worst-case scenarios(in the case of temperature, 6-7*C by 2100 under BAU, if most or all feedbacks play out to their worst possible extent) are possible, but not at all inevitable.
2.)Human extinction is technically not possible because of climate change alone, contrary to the views of some. Obviously, we can't predict what else will happen 10, 100, or even 1,000 years from now. But given that out ancestors have in fact, survived a few disasters about as bad, and in certain cases, far more acute, than even the worst case of AGW could be; the eruption of Toba, a supervolcano about as powerful as Yellowstone, 72k years ago, took the human population from some millions, down to about 100,000 or so people.(The planet dodged a major bullet overall, though: current scientific evidence says that Toba, suprisingly enough, actually didn't cause any major extinctions. Research indicates that we may not be so fortunate if Yellowstone blows, though. Only time will tell), I just can't give any credence to this particular theory.
3.)There do seem to be a few on here who seem to be of the opinion that it's too late to do anything about climate change. The vast majority of scientific research I've seen seems to indicate otherwise. One article I often link to is a Skeptical Science post concerning a well-known Pacala & Sokolow piece on climate "wedges". It's from 2004, so it's a bit old, but there's plenty of decent information. Here, see for yourself:
