Exactly this! I believe global warming can become an inconvenience but nothing totally off the scale compared to the problems we face today (and especially have faced in the past). If there is even a 1% chance of a nuclear war that would be much more devastating (even in expected value) than climate change. I actually have grown to fear the opposite: We come up with an efficient cycle to capture carbon (like the one to create starch that was all over the news some time ago) and suddenly it becomes a race to the bottom where we need international treaties so people are not sucking all the carbon from the atmosphere. I have no clue about chemistry whatsoever so I can hardly tell if this is plausible but if it is, it appears far more dangerous to me than a couple degrees in global warming.
