Yesterday, on August 25, 2009, the UN's top climate scientist has, for the first time, backed ambitious goals for slashing greenhouse gas emissions that many climate negotiators say are beyond reach.

Rajendra Pachauri, head of the IPCC, said clearly and unequivocally that 350 is the number.

"As chairman of the Intergovernmental Panel on Climate Change (IPCC) I cannot take a position because we do not make recommendations," said Rajendra Pachauri when asked if he supported calls to keep atmospheric carbon dioxide concentrations below 350 parts per million (ppm).

"But as a human being I am fully supportive of that goal. What is happening, and what is likely to happen, convinces me that the world must be really ambitious and very determined at moving toward a 350 target," he told Agence France Presse in an interview.

Pachauri, who has an oil and gas background (he was on the Board of Directors of the Indian Oil Corporation (January 1999 to September 2003), was the guy handpicked by Bush to replace the "alarmist" Bob Watson.

We have the technology to meet the goal. What we lack ...
