By this weekend's conclusion of the Cancun climate conference, representatives of nearly 200 governments had agreed to create a Green Climate Fund to foster environmentally friendly development in poor countries. The deal also sets up new incentives for nations that protect their forests. But attendees back-burnered the issue of establishing an international treaty to reduce emissions of heat-trapping greenhouse gases — something that has proved elusive over 20 years of negotiations. Does that mean Cancun was a failure or should any deal be considered progress? (Watch a report about the summit's end)

Cancun was a failure — and this deal will be, too: The only thing Cancun accomplished, says Kirsty Wright in World Development Movement, was to "lower expectations" so far that even an agreement filled with "hollow promises" is being celebrated. The new climate fund will be managed by the World Bank, "one of the world's most discredited and undemocratic institutions." And, if history is any guide, wealthy nations will renege on their promises to pump billions of dollars into the fund, making this a disappointing "Christmas present" indeed.

The conference at least restored U.N. credibility: This "modest deal" might not save the planet, says Suzanne Goldenberg in Britain's Guardian, but it salvaged some credibility for the conference's U.N. organizers. After last year's disastrous Copenhagen talks, another breakdown in Cancun could have killed these "dysfunctional" climate negotiations for good.

Actually, Cancun was a big success: Cancun was "a diplomatic triumph," says Fred Pearce in New Scientist. Dozens of nations — "rich and poor, forested and industrialized" — proudly made it clear they are willing to act unilaterally to make a "remarkable new low-carbon world" a reality. A global commitment is still proving elusive, but as long as Brazil, for example, is dramatically reducing deforestation in the Amazon, there's hope.
