I am also a daily lurker and I noticed the lack of comments as well. One question I have left no wanted to ask. What does the April sea ice volume need to drop to in order to make a virtually ice free September likely? I would guess at anything less than 20 000 km3.

D Peguin. Graphs on p473. It is so interesting that any reduction in first twenty years is quite big and if we were to cease all emissions now, we would be at the well advertised of CO2 safe level of 350ppm really quickly.

Hi. A very good reference for land and ocean uptake for anthropogenic CO2 is ar5 biogeochemistry chapter 6. It seems take Rob Dekker is correct inasmuch as if all anthropogenic carbon emissions were to cease, Atmospheric CO2 would decrease at about 2ppm initially. https://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_Chapter06_FINAL.pdf
