Panel member John Holdren of Harvard University says the world must be mobilized immediately to avoid catastrophe. "Climate change is real, it's already happening, it's already causing harm, it's accelerating and we need to do something about it, and we need to do something about it seriously, starting now. Our specific conclusions are that if the world were to go past the point of an increase above pre-industrial temperatures greater than 2 to 2.5 degrees Celsius, we would be in a regime where the danger of intolerable and unmanageable impacts on well-being would rise very rapidly," he said.
The panel's recommendations include a series of steps to cut the rate at which temperatures are rising. Chief among them are a global agreement on an acceptable ceiling for temperature rise and finding ways of adapting to cope with the damage already done.
You can bet your azz on that one.
