Hi r-enter-estered, I want to apologise for the tone of my last reply- being drunk and seeing your celebration of a post that referred to anthropogenic climate change as an 'unscientific juggernaut' was not the ideal combination. That doesn't seem like your perspective now though, and you seem genuinely interested in having a discussion about these issues.. I still don't fully understand your position though. I also don't see how Jordan contradicted himself, but I'll leave that for him to respond to.
The three perspectives you've devised don't seem to account for much- I really don't think a significant portion of people actually
want climate change. Our beliefs are shaped by fear and ignorance as much as desire. Maybe it'd be better understood as 1) I believe in... 2) I don't believe in... 3) Reality/science, with 1 and 2 accounting only for a lack of awareness, or in the case of 2, possible awareness + denial.
Your observations about the climate either warming or cooling seem very 'black and white'/'all or nothing' in nature. Obviously you were putting it plainly, and communicating a preference for warming, rather than cooling. But even if some warming is inevitable, wouldn't you prefer relative stability to unbridled, destructive warming?
As for the effects of humans on climate, just to put things in perspective, here's a handy graph which shows the extent to which greenhouse gases have influenced global temperatures since 1900, relative to external natural processes:
Sorry for the large image, I have no idea how to resize it. Anyhow the data shows that greenhouse gas emissions have risen at an exponential rate since the Industrial Revolution, resulting in an unprecedented contribution to overall temperature increases. This is the specific anthropogenic climate change which I suggested would be ridiculous to deny.
About Mann's inaccurate projections: although we're not living at the warmest time presently, the scientific consensus predicts global temperatures to reach the highest since meteorological recording began by around 2050. Along with up to 35% of species going extinct by then, unless greenhouse gas emissions are reduced by ~70%.
And in response to your claims about people who 'wish there to be an anthropogenic cause of (weather severity)'- current projections actually indicate that this is likely to occur in the future. Warmer temperatures allow for greater moisture and humidity in the atmosphere, which doesn't necessarily equate to more storms, but more
intense storms, since storm severity is largely determined by humidity.
I hope this wasn't too apocalyptic; if you're concerned about climate change, go veg or vegan! It's probably the best thing we can do for the environment at the moment.
