The US will again double the money it gives to help developing nations respond to climate change, President Biden has announced.
Mr Biden said in April that America would double its contribution to $5.7bn (£4.2bn), but speaking at the United Nations General Assembly he said it would increase again to over $11bn (£8bn).
In his first appearance at the UN since taking office in January, the president said he would work with the US Congress to secure the extra money.
Mr Biden hopes this commitment, along with increased private finance and contributions from other donors, will help developed countries meet the long-promised goal of delivering $100bn (£73bn) a year for developing countries to deal with the crisis.
The pledge was made in 2009 and was supposed to be achieved by 2020, but was missed by about $20bn, with the greatest shortfall coming from the US, according to ODI analysis.
The news will likely be welcomed by the British Prime Minister Boris Johnson who has used the Assembly to galvanise commitments on climate finance ahead of COP26, crucial climate talks hosted in Glasgow in November.
Meeting the climate finance pledge is seen as key to securing a successful outcome to COP26, where developing countries – who have usually done the least to contribute to climate change – will be reluctant to engage and make ambitious climate pledges without sufficient funding help.
President Biden told the UN the world must “work together as never before” in a year that has “brought widespread death and devastation from the borderless climate crisis” in the form of “extreme weather events… in every part of the world”.

PM: COP26 a ‘turning point for the world’
“Scientists and experts are telling us that we’re fast approaching a point of no return,” warned the president.
He laid down the gauntlet to other nations, urging every state to “bring their highest possible ambition to the table” at COP26 in order to “keep within our reach the vital goal of limiting global warming to 1.5C”.
Mr Biden has been keen to re-establish America’s prime position on the world stage, as well as international alliances, after years of “America First” policies under Donald Trump.
He moved to reinstate the US commitment to the Paris climate agreement just hours after being sworn in.
Many more leaders will address the UN General Assembly on Tuesday, including Iran’s recently elected hardline president Ebrahim Raisi, and Chinese President Xi Jinping – who will give a pre-recorded video address.
