Current approaches to deal with climate change are ineffectual, one of the world's top climate scientists said today in a personal new year appeal to Barack Obama and his wife Michelle on the urgent need to tackle global warming.

With less than three weeks to go until Obama's inauguration, Prof James Hansen, head of Nasa's Goddard Institute for Space Studies, asked the recently appointed White House science adviser Prof John Holdren to pass the missive directly to the president-elect.

Obama spoke repeatedly during his campaign about the need to tackle climate change, and environmentalists fervently hope he will live up to his promises to pursue green policies.

The letter, from Hansen and his wife Anniek, is a personal plea to the first couple. It begins: "We write to you as fellow parents concerned about the Earth that will be inherited by our children, grandchildren, and those yet to be born … Jim has advised governments previously through regular channels. But urgency now dictates a personal appeal."
