  1.  @AvangionQ  300ppm or less is insanely dangerous, when glacial maximums happen it drops to some 180ppm and mass plant extinctions happen 150 to 100ppm. We are recovering from a treacherously low CO2 level that caused the most unstable climate in 10's of millions of yrs. Losing plant life is the end of everything. Better warmer than colder.

  2. Annual sea level rise has been the same for 200 yrs. Guess stone age Native Americans were driving their SUVs too much.
