- NASA climate chief James Hansen says:
- At current temperatures, no "cushion" left to avoid dangerous climate change
- "... even small global warming above the level of the Holocene begins to generate a disproportionate warming on the Antarctic and Greenland ice sheets."
As global temperatures rise to be 0.8 degrees Celsius warmer than the pre-industrial level, is the planet already entering a zone of dangerous climate change?
With Arctic sea-ice in a "death spiral", Greenland in 2010 melting at an unprecedented rate, a seemingly extraordinary number of extreme climate events in the last year from the Russian fires to the Pakistan floods, and 18 countries setting new temperature records, have we already gone too far for a safe climate?
