re: #110 lostlakehiker
If we get everything wrong from now forward, that’ll cost us billions of lives. The world cannot subsist in the face of back to back 50-percent crop failures across, say, N. America and China. If 1 degree is as bad as we’re now seeing, what else can we expect in a 10-degree-hotter world?
Excellent comment overall.
In answer to your question:
A 10 degree (I assume you mean F rather than C) would likely mean crossing an SO2 tipping point. That would mean a lethal percentage of our atmosphere would become SO2. This is what killed the trilobites after several thousand years of intense volcanic activity (which released CO2 at a much lower rate than were are doing right now). It would mean the death of all mammals on the Earth including us.
