This is a tough issue for me. In reality, the science speaks for itself. Global warming is real. Humans contribute to it. You can argue about the degree to which we continue, but you can't rationally argue that there is no contribution, nor can you rationally argue that it's not a big deal.
So instead, global warming deniers are not relying on reason. They're relying on propaganda and emotional arguments. They're relying on mocking the science and using such buzz words as "alarmist."
And they're quite good at this.
So we have to be clear: it's not just about getting the science and the information out there. It's not just about winning the argument. It's about winning the argument in a way which is clear and obvious to people and hits them not just on an intellectual level, but an emotional one as well.
And in doing this, we need to present clear and simple alternatives for everybody.
The thing is that, to an extent, we're succeeding at this. Retailers are finding that if they promote their eco-friendly nature that it's profitable to them, so they're trying to change their image by becoming better corporate citizens. People are using the phrase "carbon footprint" in everyday language. This is all good.
But it's not enough. We need to truly transform how we look at this planet and how we interact with it and we need to find a way to do so which doesn't so much lecture people as encourage them to change in their own way. I constantly see people who want to find a better way of doing things, but don't have the resources or the tools to do so. We need to help them find those tools. Low-energy light bulbs and fuel-efficient vehicles are a start, but that's all they are. We shouldn't be thinking of 50mpg as fuel-efficient. We should be thinking of that as the absolute minimum standard for fuel efficiency. Until we change that mindset, we're not going to really solve the problem.
