"No developing country will sign up to an agreement that could give them no extra money at all. The EU and other rich countries must provide new and additional finance, otherwise there will be no deal at all," said Rob Bailey, Oxfam's senior policy adviser. Developing nations have been unanimous and implacable on the terms of the finance deal.
The scientist who convinced the world to take notice of the looming danger of global warming says it would be better for the planet and for future generations if next week's Copenhagen climate change summit ended in collapse.
James Hansen talks to Suzanne Goldenberg Link to this audio In an interview with the Guardian, James Hansen, the world's pre-eminent climate scientist, said any agreement likely to emerge from the negotiations would be so deeply flawed that it would be better to start again from scratch.
"I would rather it not happen if people accept that as being the right track because it's a disaster track," said Hansen, who heads the Nasa Goddard Institute for Space Studies in New York.
"The whole approach is so fundamentally wrong that it is better to reassess the situation

investigation of how injecting large quantities of precisely engineered particles into the upper atmosphere might provide a cost-effective tool for climate intervention – geoengineering.
The idea of using aerosol particles for messing with climate change isn’t a new one – the idea of injecting sulfate aerosols into the stratosphere to reflect more sunlight away from the earth has been around for a while.......
........precisely engineered particles not too dissimilar from those that David described back in the 1990′s, which got me wondering whether techniques being used then for fabrication of silicon particles could be used for the more complex particles being proposed here....
Proposed self-aligning, levitating, sunlight-reflecting nano-disc (Keith, 2010)
In a nutshell, David’s idea is to engineer discs around 10 micrometers across and 50 nanometers thick, with a core of aluminum, a top layer of aluminum oxide, and a bottom layer of barium titanate. Injected high enough into the atmosphere

Hansen... Hansen.... Hmmmm
It was a Hansen that told us about the atmosphere on the moon in the 1800's
Hansen Hypothesis 1856, Peter Andreas Hansen, one of the leading mathematical astronomers on the Continent,
It was a Hansen that was curator at Lick Observatory when we tried to see the Moon pictures (never got to look)
Curious coincidences
Here I examine the possibility that engineered nanoparticles could exploit photophoretic forces, enabling more control over particle distribution and lifetime than is possible with sulfates, perhaps allowing climate engineering to be accomplished with fewer side effects. The use of electrostatic or magnetic materials enables a class of photophoretic forces not found in nature. Photophoretic levitation could loft particles above the stratosphere, reducing their capacity to interfere with ozone chemistry; and, by increasing particle lifetimes, it would reduce the need for continual replenishment of the aerosol. Moreover, particles might be engineered to drift poleward enabling albedo modification to be tailored to counter polar warming while minimizing the impact on equatorial climates.

After reading the article and the different posts, there are a few questions that many people need to be asking that are not.
What exactly are the long term consequences of the actions that they are propsing and the effects to the overall environment? Some of what they are proposing, sounds very risky and dangerous, as well as looks like it would cause more problems than what is already there present.
