  1. That’s the chart that can give me insomnia. When the climate changes state due to Milankovich forcings, temps just go straight up like an elevator, and — in geological time — instantly. 13F. 14F. Just like turning on a light switch. The scary thing is that the climate forcing due to increases in GHGs is an order of magnitude larger than that from orbital changes.
