Apparently we want to set Earth’s climate control knob at 1.5C above the Little Ice Age. If the IPCC is right, we can use cars, hairdryers and air-conditioners to do it. All we need to know is equilibrium climate sensitivity (ECS) and then we can work out the right atmospheric level of CO2 to aim at. Easy, right? Now I don’t believe the IPCC has it all right, but the IPCC believes the IPCC, and therefore they’ve done this calculation. It’s what the whole Paris convention was for, eh? But the answers turn out to be a bit surprising. Basically, if the climate modelers are right, and equilibrium climate sensitivity is 3C, the CO2 concentration we need to aim for is … wait… 400 ppm. How many years have we got to change the whole “human emissions” equilibrium and discover 100% clean energy? Answer: No years. If CO2 is the dominant climate driver, we are already at the “max” set point that 40,000 people in Paris just decided was the holy grail new ambitious target. Turn off the lights, stop the planes, get on your bike. The warming is in the can already. Bear in mined that it is “equilibrium” […]Rating: 0.0/10 (0 votes cast)
