Well, you are right about that. Nobody knows for sure. It's a gamble. How much do you want to bet? Wanna go all in and bet your entire civilization?

Yes, 50 years is a tiny speck of time. The most interesting thing to me on the second graph is the red line line at the very very far right edge of the graph that spikes straight up. You have half a million years of history and in our "tiny speck" of time the CO2 shoots to the highest level in the whole history. It's perfectly straight up. Nowhere in the entire history does it go up as steeply or as high. Fastest change and highest magnitude in the whole 500,000 years occuring within a generation or two. Can't wait to see what happens next!
