Can you name one scientifically demonstrated consequence of the climate chaning we don't know how to deal with? That's why I say it. By all means. Let me know what we can't handle, but as far as I am aware we know how to handle the climate. In fact we've become so good at it that people who dies from climate related disaster have plummeted the last 100 years. Scientist say that the climate is changing but it's not catastrophic and it's not something we don't know how to handle. Even the latest IPCC report has toned down their fear of the future.
