pdotb@wyrms.de reviewed Our Fragile Moment by Michael E. Mann
Interesting overview of paleoclimatology
4 stars
Covers a number of previous extinctions and climate anomalies (think P-T, K-Pg, and PETM, among others) and draws lessons from them for today's climate change. Somewhat optimistic as Mann doesn't think warming will trigger a methane catastrophe, but his explanation of hysteresis really makes clear how overshooting and then hoping to recover really doesn't work.
