Overwhelmed by the rapidity of human-caused climate change, the dire implications of feedback loops like methane and CO2 release from thawing permafrost, and the utter failure of world governments to make the steep greenhouse gas emissions cuts necessary to keep global warming below 2 degrees C, scientists are paying…
Those of us who read James Hansen’s Storms of My Grandchildren years ago have been haunted ever since by the vision of “tipping points” that would take climate change beyond human control. The term “tipping points” as used in climate science means the critical point in an evolving system beyond…

The increase is due to ever-rising fossil fuel burning in the developed world as well as in China.…
Climate change is happening with a rapidity scientists did not predict—the Arctic is melting faster, sea level is rising faster, and Co2 levels are fast approaching the point where the world will not be able to restrict global warming to the 2 degrees Celsius (C) that scientists warn is…
