By the way, this is a terribly asked question. You embed a wide range of assumptions and made some noob mistakes as well.<p>You actually have a collection of different questions:
1) Where can I have a reasonable fact-based argument about climate change?
2) I've noticed I got banned, possibly due to ideology, can I avoid doing that?
3) Are opinions on climate change entirely associated with the ideological bent of people running the servers<p>Here's what you got wrong:
1) Climage change isn't a far left opinion. It's actually fairly centrist, for example I am a democrat but not very progressive, much closer to Republicans than most democrats. So I'm as right of the far left folks as you can get. My ilk don't question climate change, because a wide range of intelligent people have put together a good collection of resources to make a convincing argument. Even republicans are gradually coming around to the idea that climate change is real, it's human caused, and we need to start making some hard policy decisions to deal with it.<p>2) you said you're a programmer with a stock market hobby, so you're analyzing things. So what? Analysis is fine, but you're analyzing things far outside your normal expertise zone, and these are complicated problems with huge amounts of prior knowledge, being communicated mainly to experts in the field.<p>3) there are lots of people making weak, psuedoscientific arguments about climate change that are just believeable enough that quantitative people fall for them. THey sound right, they seem to add enough question to the issue, but they don't really. It's just far easier to make weak pseudoscientific arguments than it is to make strong scientific ones.
