Obama: We're not moving fast enough on climate change

World leaders must agree to cut carbon emissions at a UN summit in December because the climate is changing faster than efforts to curb global warming, US President Barack Obama has said during a visit to Alaska.

The three-day visit is aimed at highlighting the state's melting permafrost and eroding coastlines.

During the visit, US President Barack Obama will trek with British TV adventurer Bear Grylls to observe the effects of climate change on the area.

Obama is trying to build support for tough new rules on carbon emissions from power plants ahead of a hoped-for international climate deal at a UN summit in Paris in December.

Speaking at a meeting of foreign ministers in Alaska, Obama said: "Climate is changing faster than our efforts to address it. That ladies and gentleman must change. We're not acting fast enough.

"This year, in Paris, has to be the year that the world finally reaches an agreement to protect the one planet that we've got while we still can."

The deal asks countries to submit national plans on how they will deal global warming early next year ahead of a crucial summit in Paris.

Developing countries, including China and India, had expressed concern at earlier drafts that they claimed could impose too heavy a burden on emerging economies.

But agreement was finally reached with the final draft saying countries have "common but differentiated responsibilities" to deal with global warming.

"As a text it's not perfect, but it includes the positions of the parties," Peru's environment minister Manuel Pulgar-Vidal said.

Britain is set to pledge hundreds of millions of pounds to a United Nations "green bank" intended to help poor countries prepare for the impact of global warming.

The announcement is expected at a pledging conference in Berlin on November 20, after Prime Minister David Cameron said the UK would "play a very positive part" in supporting the Green Climate Fund.

No specific figure has yet been confirmed for the UK's contribution, but energy minister Amber Rudd said earlier this month that Britain will donate "strongly" to the fund.

Speaking at the G20 summit, Mr Cameron stressed that the money will come from funds already earmarked for international development and does not represent a new financial commitment.
