Humanity and Climate Change
Posted on November 25, 2016 by William (Bill) Siebold
How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree… We don’t have much time left.
This is a quote by James Hansen
“If humanity wishes to preserve a planet similar to that on which civilization 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 350 ppm… If the present overshoot of this target CO₂ is not brief, there is a possibility of seeding irreversible catastrophic effects.
It would be immoral to leave young people with a climate system spiraling out of control.”
