Emissions up in developed nations
Roger Harrabin, BBC
Emissions of greenhouse gases by industrialised nations rose 2.3% from 2000 to 2006, according to new figures from the UN’s climate change agency.
The biggest increases were in the former Soviet bloc – and Canada.
A UN spokesman said countries had to work much faster to avoid the possibility of dangerous climate change.
Next month the nations of the world meet in Poland for the annual negotiations on climate change.
The new figures do not offer a great deal of optimism…

Geoengineering ‘no substitute’ for climate targets, UK minister warns
James Randerson , The Guardian
Research into drastic solutions to climate change such as cloud seeding, sun shades in space and ocean fertilisation risks hampering global climate negotiations by giving some countries an excuse for not agreeing to short-term emissions reductions, a UK government minister warned today.
The remarks by Joan Ruddock, a minister in the Department of Energy and Climate Change, appear to be a thinly veiled dig at the Bush administration, whose delegation attempted to insert a section into last year’s Intergovernmental Panel on Climate Change (IPCC) report on developing technology to block sunlight and cool the planet. The proposed text referred to it as an “important insurance” against the impacts of climate change.
Speaking to MPs on the Department for Innovation, Universities and Skills select committee, Ruddock was defending the government’s unwillingness to fund research into so-called geoengineering – large-scale, untested interventions that either soak up carbon dioxide or prevent sunlight warming the planet
“The concern is that people who don’t want to enter into agreements that mean they have to reduce their emissions might see this as a means of doing nothing, of being able to say, ‘science will provide, there will be a way out’,” she said, “it could be used politically in that way which would be extremely unfortunate.”…

The greenhouse gas that nobody knew
Yale Environment 360, via The Guardian
When industry began using NF3 in high-tech manufacturing, it was hailed as a way to fight global warming. But new research shows that this gas has 17,000 times the warming potential of carbon dioxide and is rapidly increasing in the atmosphere – and that’s turning an environmental success story into a public relations disaster.
Hypothetical question: You’re heartsick about global warming, so you’ve just paid $25,000 to put a solar system on the roof of your home. How do you respond to news that it was manufactured with a chemical that is 17,000 times stronger than carbon dioxide as a cause of global warming?
It may sound like somebody’s idea of a bad joke. But last month, a study from the Scripps Institution of Oceanography reported that nitrogen trifluoride (NF3), with a global warming potential of 17,000, is now present in the atmosphere at four times the expected level and rapidly rising. Use of NF3 is currently booming, for products from computer chips and flats-screen LCDs to thin-film solar photovoltaics, an economical and increasingly popular solar power format…
