Sure, that's one of the biggest obstacles we have on this issue - climate doesn't respect national boundaries.
I agree that climate change is exploited politically, exploited by corporations, exploited by the media and exploited by marketing executives who want good PR for their brands. And much of the news about it IS overly alarmist and taking "worst case scenario" predictions and reporting them as fact. All of this is true.
You're also correct to say that our solutions to climate change are so politicised that it's a minefield trying to separate solutions that will actually help with solutions which are using the issue to push a different agenda. Renewable energy for example is a linked but different issue from climate change that has somehow become mixed together by people like in your electric cars example.
However, the misuse of climate change by people looking to exploit it is not the fault of the data. The data has no agenda or morality, it is just raw data. And that does show a heavy correlation between human activity and the heating of the planet. It's not the science's fault that it is being used badly. The climate change phenomena is real even if it is been used for fantasy solutions.
You might enjoy these (rather long) videos about climate change. They are by a climate science journalist who has spent much of his life trying to debunk the issue and the myths spouted by both the left and right wings by focusing strictly on the science. Here, he looks at potential Governmental climate change solutions from a conservative rather than left wing mindset:
Thanks for your well argued reasoned response.. The video and what he says Makes complete sense to me. If we are going through a global warming/climate change and how we should go about it is what should happen as in that video.
The part on china opened my eyes, also the fact that with wind farms and solar can make to much electricity, its up to us to figure this out and how to this solve that problem.
