Bangkok negotiations: US concedes on funding as accusations fly
At the ongoing pre-Copenhagen climate talks in Bangkok, the US has made a step towards resolving the deal-breaker issue of funds to help developing countries respond to climate change. The Guardian’s all over it, perhaps thirsting for some good news to break up the drumbeat of doubt we’ve heard lately on the climate policy front.
The slight but significant shift is that the US now agrees with developing countries that money for mitigation and adaptation should come through a new, single, independent fund administered at least partly by the UN. Before, the US had argued for sticking with existing funding bodies like the World Bank, an institution disfavoured by the global South for its policy of loaning, rather than aiding, money.
But critical questions on climate funding are still up in the air - not least the numbers to be written on the cheques. And on other issues, the US stands accused of putting on the brakes. As the AP reports, it is increasingly being recast in the familiar role of climate villain.
Details are few on the negotiations, which are sealed off from press. But an anonymous EU source told the Guardian last month that the US team is putting forward a new framework for the Copenhagen deal that would scupper Kyoto-style policy. Instead of working top-down to divide a global emission cut among countries, the US reportedly wants the deal to be a patchwork of national commitments, each with its own rules and timetables.
Add to this the long-running demand for emissions commitments from emerging economies like India and China, and they’ve got the developing world in a righteous fury. Yesterday, China was joined by the head of the G77 (which has grown from the eponymous 77 to a group of 130 developing states ) in a coordinated statement charging that rich nations collectively - not just the US - intend to kill Kyoto.

Global warming doesn’t just change the weather, it also affects the ozone layer. According to a detailed new modelling study, by 2095 the springtime UV index (UVI) could go up by as much as 20% on the southernmost section of the planet, as altered atmospheric circulation pushes more stratospheric ozone into the Northern Hemisphere. That’s nearly half the UVI increase caused by ozone-eating pollutants in the late twentieth century - but coming from climate change alone.

A new reservoir of fossil fuel could be ready to tap much sooner than previously thought. R&Ders have been talking up natural gas extraction from methane hydrates - a solid form of the greenhouse gas, found tucked away beneath the sea floor where low temperature and high pressure keep it stable.
Rice paddies produce an estimated 20% of the methane released by human activities. But according to data presented at a Beijing climate conference last week, a switch to certain farming practices could erase most of those emissions. Jane Qiu reports on the research over at
In this year’s series of UN climate talks - the latest of which took place last week in Bonn - one of the issues negotiators are sinking their teeth into is a source of greenhouse gases that has previously been sidestepped. Chopping and burning trees causes an estimated one-fifth of global emissions, and slowing down deforestation could be the cheapest and quickest way to keep a substantial load of gas out of the atmosphere. With this in mind, the Bali meeting in 2007 called for a decision on forests to be made by the time the 2009 talks wrap up in Copenhagen this December.

A reconstruction of the Earth’s climatic history during a key hot period 55 million years ago has highlighted a yawning gap in our understanding: this period’s rise in carbon dioxide accounts for just half of its warming. Some as-yet-unidentified climate feedbacks could be at work, the scientists behind the research conclude.
Take a country at any point in the future, say the authors, and you can estimate how its projected greenhouse gas emissions are distributed among its citizens by assuming that people with higher incomes emit more. You then put all these high and low emitters of the world into a single distribution and chop off the top of the curve (see right) - taking out a bigger or smaller section depending on how much gas you want to exclude from the atmosphere. This yields a recommended ceiling on individual emissions - in this example, about 10.8 tons CO2 per person per year - that applies equally to all countries. To then come up with a national target, follow the cartoon below.
The authors also try a scenario with an added twist: an emissions floor as well as a ceiling. The idea here is to alleviate extreme poverty by letting people who are now using less than, say, a ton of CO2 per year come up to that low level. The group at first had doubts about this complication, says Socolow, “but we found that if we allow fossil fuels where they’re useful, the extra work that the rest of us have to do is very small.”
At the
As the Earth has alternated between glacial and inter-glacial periods, the steep climatic ups and downs have gone hand in hand with changes in atmospheric carbon dioxide levels. But where was the CO2 going to and coming from? Scientists have pointed to the ocean – currently a vast sponge for the greenhouse gas.

One noteworthy observation at December’s AGU conference – the latest and largest ever gathering of earth and space scientists – was the attention being given to a threat conceivably worse than carbon dioxide. In numerous talks, during poster sessions and over coffee, scientists were discussing methane – a greenhouse gas with a warming potential 25 times that of CO2. 
Researchers have discovered new hot spots for emissions of the greenhouse gas nitrous oxide: barren patches of peat dotted across northern tundra. And warming in the Arctic - just as it threatens to multiply emissions of carbon dioxide and methane from
