The headline today is that emissions pledges don’t match needs. A leaked UNFCC secretariat memo indicates that current commitments hit 3C.* A ClimateInteractive reference is scrawled in the margins. It’s interesting that this is regarded with surprise, as we said it in March, Rogelj et al. said it in Nature in June, and it was intuitively evident before that. Climatescoreboard, climateactiontracker, and others are now monitoring the possible outcome in near-real-time. Our dream, over beers in Copenhagen on Thanksgiving in 2008, was to provide fast feedback to inject some reality into negotiations. It’s working!
* Update: As Joe Romm points out, the Guardian and other coverage is just wrong. The secretariat analysis covers current commitments prior to COP15, not possible deals. The various drafts circulating (as you can see in analysis here this week) yield a wide range of outcomes, including 1.5C. There’s no way to nail down the final outcome until the contested bracketed text in the drafts is finalized.
Update 2: We at ClimateInteractive are doing lots of evaluation of draft language using C-ROADS and a simpler emissions model that I developed, but we’re not going to report on the outcome until there’s a definitive text. Some of the insights from that analysis are reported in posts here this week, but obviously it’s all hypothetical at this point.
