The United Nations Climate Change talks kicked off yesterday in Cancun.  For many, the mood began much more sombrely than last year.  Copenhagen attracted celebrity clout, world leader buzz, and a sense of optimism for a binding agreement.  For all Copenhagen promised, however, those who hoped for a fair and binding global deal left empty handed.  

Along with analysts, pundits and the blogosphere, the U.S., UK and EU are already downplaying the chances of a deal being reached in the next fortnight.  And as Desmogblog reported today, those fears may not be in vain with threats that the U.S. may pull out of the talks early. 

The talks during the next two weeks are going to focus largely on forests and finance, but also on questions about the legal status of a future agreement and emissions targets, which are expected to be tackled beginning next week when ministers arrive.

The sense of general pessimism around the talks has led some to question the viability of the UN Framework Convention on Climate Change (UNFCCC) to deliver, and has led others to manufacture doubt over the scientific basis for action.  A new report released by Oxfam argues that despite the disconsolate atmosphere, a year of extreme weather conditions demonstrate more than ever that a binding climate agreement under the UN auspices is imperative.  The report, More than ever: climate talks that work for those that need them most, presents the weather events that have devastated much of the planet in the last year, and the even more harrowing costs of climate inaction.  

According to the report, at least 21,000 people died due to weather-related disasters in the first nine months of this year – more than twice the number for the whole of 2009.  “This year is on course to experience more extreme-weather events than the 10-year average of 770. It is one of the hottest years ever recorded,” wrote Tim Gore, Oxfam’s EU climate change policy adviser and report’s author.

After eight years during which the United States was consistently derided as the most obstructive force in international climate negotiations, Canada moved into worst place today, receiving the “Colossal Fossil” award for having done more than any other country to drag down talks at the UN climate negotiations in Poznan.

Honda Motor of Japan has launched the world’s first hydrogen-powered fuel-cell vehicle intended for mass production.

Although it will make just 200 of its FCX Clarity vehicles over the next three years, Honda plans eventually to increase production, especially as hydrogen filling stations become more common.

And even the small initial run represents progress toward a clean-burning technology many have rejected as too exotic and too expensive to gain wide acceptance.

Two new Exchange Traded Funds, filed within days of each other with the U.S. Securities and Exchange Commission, will focus on companies that provide products and services to the wind-energy industry, such as turbine makers and utilities with wind farms.

Wind energy reduces carbon dioxide emissions and cuts natural gas and water use. Of particular interest to investors, wind power is unaffected by price swings in natural gas, coal and uranium — all of which soared this year.

The new filings reflect the deepening role of wind in the battle against climate change.

The most interesting aspect of the 1,700 prominent signatories urging U.S. politicians to make immediate, deep reductions in greenhouse-gas emissions is that so many of them are economists.

Predictably, the statement by the Union of Concerned Scientists, issued on the eve of U.S. Senate debate on the Lieberman-Warner climate bill, affirms the long-standing scientific evidence for global warming.

But what was unusual, and surprising, was the prominent role of economists as measured by the statement that acting quickly to cut emissions “would be the most cost-effective way to limit climate change.”

After virtually abandoning the issue for three decades, the environmental movement got a bold reality check this week from a new book highlighting relentless human population growth as a driving force behind global warming.

This wouldn’t have raised eyebrows in the 1970s, when the modern environmental movement had its genesis and Paul Erlich’s “The Population Bomb” was on just about everybody’s bookshelf.

Since then, however, overpopulation has dropped from the vocabulary of most environmentalists despite a near doubling of the world’s numbers to an estimated 6.8 billion people today.
