I think the mainstream media is doing a poor job explaining climate change concerns. We know this because too many people think that there's imminent threat, when that's really not what the scientists are talking about. And we know that there's a 'fake' scientific popularization movement trying to obfuscate things, because we're still getting people talking about water vapour, or solar rays, or (I guess) magnetic poles.
I watch the scientific media quite a bit (i.e., not the main media, but the media intended for scientists talking to each other), and there is a wipespread concern about global warming and about CO2 pollution. It's a real deal. Something to be worried about.
Many people think we should worry about other pollution, instead of CO2. Hey, if that's what they think, then power to them. But, I really wish they'd be proactive about it. Instead of just pointing a 'other pollution' to explain why they don't care about CO2, they should help do something about that 'other pollution'. In the short-term, it's probably a bigger actual threat, though it's also more obvious
