How on earth did these subheadings end up in the final #COP decision? (1) "United in celebration", (2) "Policy cycle fully in motion", (3) "Responding to urgency". Given the pace of "progress" and the severity of the problem, this PR language is outright cynical.

2300 is as many years away from today as David Hume's "Enquiry into the Human Mind". The "moderate doubt" that he recommends in his scepticism is a basic principle of climate science: it tests its results and itself again and again. The findings, however, leave little room for doubt.
New study comparing an ensemble of 16 ice-flow models: if we continue with increasing emissions, we'll cause meters of global sea level rise. Up to 7 meters (!) by year 2300.

GHG accounting is meaningful only when it is rigorous. But some accounting systems allow "passive CO2 uptake". The authors of this paper argue: CO2 emissions drive warming until entirely removed. Targets should require geological net zero. Curious to see how this will be received in the CDR debate.
