My conclusion is that we are still left with a fair chance to hold the 2°C line, yet the race between climate dynamics and climate policy will be a close one. The odds for avoiding DAI may be improved by aerosol management as suggested by R&F (taking the warming components such as black carbon out first), and even techniques for extracting atmospheric CO2 (like bio-sequestration) might eventually prove necessary. However, the quintessential challenges remain, namely bending down the global Kyoto-GHG output curve in the 2015–2020 window (further procrastination would render necessary reduction gradients too steep thereafter) and phasing out carbon dioxide emissions completely by 2100. This requires an industrial revolution for sustainability starting now.
