From what I gather, the climate change we are in store for will be rather devastating and nothing like what we've seen so far. Technology has helped us to grow more and more food but the world in 20 years, supposedly, is going to be far far different from what we know now.
I hope they're wrong. I don't want my kids to live in a wasteland. But hoping something is wrong shouldn't cloud our judgement on the dire situation we may find ourselves in. In these studies a lot of problems are things like runaway heating from permafrost melting, and disease and famine caused by insects that are restricted now in where they can go and the seasons they can spread/breed.
