Obama, who telephoned British Prime Minister Gordon Brown as part of their ongoing consultations, discussed the issue with him.
The President welcomed Browns yesterdays speech onclimate as making a contribution to the debate over climate change at this critical time, the White House said.
Brown, in his speech at London Zoo on Friday, called for a global fund worth $100 billion a year to tackle climate change in the developing world, ahead of crunch talks in Copenhagen later this year.
Obama looks forward to working with Prime Minister Brown and the other 15 leaders of the Major Economies Forum on Climate and Energy at the meeting he will chair in LAquila, Italy, next month on the margins of the (July 8-10) G-8 Summit to give momentum to Copenhagen negotiations, the White House said.
Apart from India, members of the MEF are the US, the UK, EU, Australia, Brazil, Canada, China, France, Germany, Indonesia, Italy, Japan, Korea, Mexico, Russia and South Africa. Obama and Brown also discussed the global economic recovery, food security, Iran and progress on Middle East peace process, the White House said.
