It's only grudgingly a plank. Politicians sought to sweep it under the rug for decades.
Politicians don't like controversial topics that might alienate corporate funders or potential voters.
Again, this is a scientific issue; discovered by scientists, researched by scientists and reported by scientists. Politicians only jumped on the bandwagon after it became mainstream news and could no longer be avoided.
It's a scientific issue, at least as far as addressing and identifying what the problem is. But when it comes to actual solutions, all they can really do is make suggestions and proposals. The politicians have to make the decisions as to what to do. I don't know if they actually jumped on the bandwagon or were reluctantly pushed.
I just wish we could get past a lot of the squabbling over what the problem is - or even that some people don't even think it's a problem.
The general public seems largely confused about the issue, but even for those who understand and believe in climate change, it's unlikely that they'd be willing to sacrifice that much. Not to mention up-and-coming nations in the developing world where the people want electronic gadgets and cars and all those things that have enhanced our lives in the West - and use fossil fuels.
So, yes, it's nice in theory for the scientists to get together and say "we should use less fossil fuels." I agree, but it's easier said than done. And "eat less meat"? People won't go along with that.
I'm not saying we shouldn't try, and I don't really want to come off as too cynical or defeatist here. But we're probably screwed one way or the other anyway. One reason I may not worry so much about climate change is that we'll probably go up in a nuclear inferno before climate change starts to really take its toll.
But at least the cockroaches will survive - and who knows? In a few million years, they may evolve into an intelligent, sentient lifeform - far more intelligent than humans. So, I do have high hopes for the planet's long-term future. I think the planet Earth will survive this, even if humans don't.
