This is all very black and white thinking. What if we do a little to limit our greenhouse gas emissions, which I think is inevitable, and we noticed our planet warms a little, and there are some more catastrophic weather events. Why would it be too late to change course after it becomes more obvious that there is a man-made climate change? Because right now, it really isn’t that obvious anything is happening with our climate, to the average person who observes what’s going on in the world around them.

I’m not saying that we should sit and wait for it to hit the fan, but to some extent I think people will. Why is it climate change totally irreversible? Won’t the CO2 in the atmosphere eventually dissipate and we have a second chance to get it right?
