" It is commonly assumed that the climate–carbon cycle response to a negative CO₂ emission is equal in magnitude and opposite in sign to the response to an equivalent positive CO₂ emission. Here we test the hypothesis that this response is symmetric by forcing an Earth system model with positive and negative CO₂ emission pulses of varying magnitude and applied from different climate states."

"Stopping climate change requires much more than emissions reductions: it requires stabilizing atmospheric greenhouse gas (GHG) concentrations. In the absence of large new additional sinks for CO₂ and other GHGs, stabilization equates to reducing emissions nearly to zero. In turn, near-zero emissions means complete transition of the world's energy supply to renewable (non-CO₂-emitting) sources. This is a huge task—one that will need to be accomplished in stages."
