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.

U.N effectively locks out reporters, others in Copenhagen

For a year, the United Nations and national leaders have stumped around the world, championing the importance of the Copenhagen climate negotiations. It made this international conclave a must-see destination. And the UN responded by granting accreditation to huge numbers of government officials, UN officials, public-interest groups and journalists. In fact, to almost twice as many individuals as the conference center could hold. And that led to pandemonium today as the UN confronted literally thousands of people waiting to pick up their security badges – people this organization couldn’t or wouldn’t accommodate.

‘Climate-gate’: Beyond the embarrassment

The United Nations Climate Change meeting, which I arrive at tomorrow in Copenhagen, is currently deadlocked on more important issues than who said what impolitic thing about somebody else in a private email to a colleague.

Greening Christmas

I love the smell of balsam and firs and decorating holiday cookies – preferably with the sound of popular holiday standards in the background. I even enjoy shopping for and wrapping carefully chosen presents in seasonal papers festooned with huge bows. So when my hosts, this week, asked what I wanted to see during my visit, the answer was simple. Take me to one of Germany’s famed Christmas markets. And literally within a couple hours of my plane’s landing, they were already ushering me into the first of what would be a handful of such seasonal fairs. But as I also quickly learned, this first was an unusual one: a "green" bazaar.
