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?

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.

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.
