Obama: Climate’s rock star

A little over a half-hour ago, President Barack Obama wrapped up a stirring pep talk to his fellow world leaders attending the United Nations climate change meeting. He didn’t promise the world. Only that the United States could be depended upon to do its part in helping stem global greenhouse gas emissions and to fund measures that would help fund the world’s poorest and climate-beleaguered nations adapt. But what was especially interesting was to watch how the whole climate conference has waited with baited breath to learn what Obama would say: Could our President make promises that would at last galvanize action in the United States and accord among countries whose views, even yesterday, seemed poles apart?

Climate emissions mandates: What role China and India?

One major schism between negotiating blocs at the United Nations climate change meeting is over which nations should face a mandate to reduce their greenhouse-gas emissions. Just the industrial powers that have historically spewed most of the carbon dioxide responsible for today’s climate troubles? Or that group and the newly emerging industrial leaders – especially China, who for several years has reigned as the world’s greenhouse-gas king? The deadline for resolving this dilemma is ostensibly quite imminent. As in today.

Tiny Tuvalu could quash climate deal

Prime Minister Apisai Ielemia brags that his tiny 9-island state of Tuvalu is the world’s smallest independent country. Its 10,000 inhabitants live an average of 2 meters above sea level, which makes their homeland highly vulnerable to disappearing with even modest sea-level rise. With the nation’s survival so dependent on climate protection, he vowed today that Tuvalu will not sign onto any climate-change accord that does not require “legally-binding” language and programs aimed at ensuring global temperatures peak at “well below” 1.5 oC. That could effectively torpedo hopes for a climate accord tomorrow when the United Nations climate change meeting is slated to wrap up.

IPCC to offer climate science scholarships

The Nobel Peace Prize will pay dividends in the developing world by funding scholarships for climate-science studies. The Intergovernmental Panel on Climate Change, which received the 2007 Nobel Prize, announced today that it is investing its winnings as seed money for these scholarships. They’d go to residents of nations expected to experience dramatic impacts of climate change.

Climate chief channels Truman, but …

On Monday, long chaotic lines kept several thousand accredited conference attendees – some standing in the freezing cold for up to 11 hours -- from being allowed to register for the United Nations climate change meeting. “Who’s to blame? Me,” said de Boer, head of the United Nations climate change office. “Part of the problem that we’re facing here is that you can’t fit size 12 feet into size 6 shoes.”

Climate: Negotiating the brackets

Representatives of 193 nations are posturing and challenging, threatening and bluffing, as they wrestle to draft a successor climate treaty to the Kyoto Protocol. The chief objective is to lower global emissions of greenhouse gases. How to do it, who will pay for it, how high to strive – all of these are up in the air. Still. Three days before the negotiators are to sign onto a statement of shared goals and intentions.
