Will Paris Conference Finally Achieve Real Action on Climate?

Six years after the last negotiations crashed so spectacularly in Copenhagen, climate delegates assemble in Paris this week to fix the world’s atmosphere. This time, despite the high security following the recent terrorist attacks in the French capital, they will meet in a better mood.

That’s because, in the preceding months, more than 150 nations have put pledges for future emissions on the table for the decade between 2020 and 2030. And the world’s biggest two emitters of heat-trapping greenhouse gases — the U.S. and China — are in harmony after a bilateral agreement in Washington last year. 

But if the diplomats enter the home stretch more optimistic than in Copenhagen, climate analysts warn that the national “contributions” on offer still don’t meet the negotiators’ self-declared task of capping global warming at two degrees Celsius. About 2.7 degrees is the most optimistic guess of the long-term outcome of the pledges. A victory for diplomacy should not be confused with a victory for the climate. 

So, is the glass half full or half empty? 

On the downside, time is running out to halt the continuing accumulation of greenhouse gases in the atmosphere. This year, the world is a record one degree warmer than pre-industrial levels — exactly halfway to the two-degree ceiling. The much discussed warming hiatus of the past decade is over
