The interesting plot is SPM.5 on p.23 of the summary for policymakers. There the emission scenarios are plotted and the thing is, the scenarios that limit warming to 1.5 K or 2 K assume actively putting greenhouse gasses back into the ground starting in the late 40ies or the late 60ies respectively. If anybody has a idea of to get the kind of policy buy in that could do something like that, I would be very interested -- otherwise fig. SPM.3 suggests Seattle should be one of the nicer places even at the more unpleasant scenarios.
