Cancun climate conference

It was time to put up or shut up. Delegates to the United Nations climate conference in Cancun knew if they came out of the talks empty-handed, the whole effort to reach a global warming treaty could collapse. The agreement that emerged over the past weekend made just enough progress to keep the talks alive for another year.

The focus of attention at the U.N. climate summit in Cancun, Mexico is global warming caused by too much carbon dioxide in the atmosphere. But there’s another impact of high carbon levels that poses a whole different set of problems: it makes the ocean more acidic.

A pair of college students from Seattle are among the members of the American Youth Delegation at the U.N. climate summit in Cancun, Mexico. They’re allowed to attend some of the negotiations, but the young people say they have a moral right to have a greater say.

When I met with Ian Siadak and Lauren Ressler, they came across as smart, articulate and well-informed. They’re also a little ticked off.

Nearly 200 countries are represented at the U.N. climate summit this week in Cancun, Mexico. There are also caucuses speaking up for the interests of women, indigenous people, and others whose voices often haven’t been heard.

Glaciers around the world are losing mass at varying rates, according to a new report from the United Nations Environment Program. Glaciers in Patagonia are shrinking fastest, followed by Alaska, then the Pacific Northwest and Canada.

Glaciers in Asia - including the Hindi Kush in the Himalayas -- are losing ice more slowly.

Other key findings of the report include:

Technology companies from around the world are gathered as part of the U.N. climate summit in Cancun, Mexico this week. The tech wizards say they can be a powerful force for fighting climate change.

In Cancun today, dozens of companies from Intel to H-P to Microsoft signed onto a statement saying information and communications technology can go a long way toward the deep cuts in greenhouse gases that scientists say we need to make in order to avoid major climate disruption in the coming decades.

Delegates at the U.N. Climate Conference in Cancun Mexico are still haggling over the same sticking points that prevented an agreement a year ago in Copenhagen: who is going to reduce their greenhouse gas emissions how much by when, and who's going to pay for it all.

And with the U.S. unwilling to sign on to the sort of strict economy-wide carbon diet being pushed by Europe and others, right now the signs of progress are few.

A year ago, the United Nations’ climate conference in Copenhagen failed to produce an international agreement on limiting greenhouse gases. Now, delegates from around the world are meeting in Cancun, Mexico to try again. But with the collapse of federal climate legislation in the U.S., regional efforts – like those on the West Coast – are coming back to the forefront.
