Longest UN climate talks end with no deal on carbon markets

MADRID (AP) – Marathon international climate talks ended Sunday with major polluters resisting calls to ramp up efforts to keep global warming at bay and negotiators postponing the regulation of global carbon markets until next year.

Those failures came even after organizers added two more days to the 12 days of scheduled talks in Madrid. In the end, delegates from almost 200 nations endorsed a declaration to help poor countries that are suffering the effects of climate change, although they didn’t allocate any new funds to do so.

The final declaration called on the “urgent need” to cut planet-heating greenhouse gases in line with the goals of the landmark 2015 Paris climate change accord. That fell far short of promising to enhance countries’ pledges to cut planet-heating greenhouse gases next year, which developing countries and environmentalists had lobbied the delegates to achieve.

The Paris accord established the common goal of avoiding a temperature increase of more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) by the end of the century. So far, the world is on course for a 3- to 4-degree Celsius rise, with potentially dramatic consequences for many countries, including rising sea levels and fiercer storms.

Negotiators in Madrid left some of the thorniest issues for the next climate summit in Glasgow in a year, including the liability for damages caused by rising temperatures that developing countries were insisting on. That demand was resisted mainly by the United States.
