"If humanity wishes to preserve a planet similar to that on which #civilisation developed and to which life on #Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm [parts per million] to at most #350ppm... If the present #overshoot of this target CO2 is not brief, there is a possibility of seeding irreversible catastrophic effects." ~ James Hansen
