Trainee PornStar posted:Just checking I got this right.. So somehow we have to reduce our Co2 emissions while simultaneously emitting enough black carbon & aerosol to stop even more warming? No, not quite, since we cannot literally stop the bulk of our emissions overnight - save by say a devastating global thermonuclear war, which would actually have the very fun effect of causing a short nuclear winter prior to the rapid temperature rise, just for that extra dose of gently caress you. What it actually means is that as we reduce our emissions, temperatures would continue to climb by both the combined effect of a) reduced global dimming, as you theorized, and b) the fact we haven't reached the stable temperature maximum for the quantity of long duration green-house gases already released into the atmosphere. The "ideal" curve is thus that temperatures continue to climb to around 2°C by mid-century, hold there for a couple decades, start reducing towards the end of the century, while for our emissions we go into zero by mid-century and further from there into the negatives, through the widespread implementation of carbon capture technologies.

Just guessing the associated construction and operating costs, I think we'd have better luck seeding and sequestering algae.
