I'm a chemical engineer, for my capstone project in school I worked on a carbon capture and sequestration process design. I had an industrial advisor that had a weird view on climate change, he believed it was real but that it wasn't caused by traditional greenhouse gasses like carbon dioxide or methane. But that it was caused by increased amounts of water vapour in the atmosphere, his argument was fairly compelling.
Here's a link to the article he wrote about the subject and presented at a couple conferences:

I have a copy to the full article if anyone wants it just shoot me a pm.
In my opinion we're fine, our kids will be fine, but their kids will be screwed. I don't believe it'll ever be too late to undo the damage we did. But undoing environmental damage unfortunately isn't financially attractive. I don't blame the politicians, I blame the corporations and their shareholders (0.0000001% blame myself as a result). I don't think we're at the tipping point, people have been saying the sky is falling for years now, but the longer we wait the more people will die as a result in the long run.
