U.N. climate summit grinds to a close after going into overtime

It was seen as an chance to show global willpower in tackling the climate crisis

but a U.N. summit in Madrid limped to a close on Sunday with major economies snubbing the bold action scientists say is needed to tackle global warming.

"We are terribly sorry Madame Chair but we cannot accept this paragraph, thank you very much."

Delegates pointed the finger at Brazil, China, Australia, Saudi Arabia and the United States - some of the world's biggest greenhouse gas emitters - for resisting calls to ramp up ambitions to cut emissions.

That meant that the conference closed with only a modest declaration on the quote "urgent need" to close the gap between existing pledges and the temperature goals of the landmark 2015 Paris climate agreement.

Many climate-vulnerable countries and campaigners had wanted to see much more explicit language.

Closing the summit, which ran on for two extra days, Chile's environment minister Carolina Schmidt said the next generations expect more from them.

(SOUNDBITE) (Spanish) COP25 PRESIDENT AND CHILE'S ENVIRONMENT MINISTER CAROLINA SCHMIDT, SAYING:

"Clearly, it is not enough. The world is watching and waiting for concrete and bigger solutions from us. We are not satisfied. The agreements reached by the parties are not enough to urgently confront the crisis of climate change.

Condemnation of the outcome in Madrid was swift.

U.N. Secretary-General Antonio Gutteres said the international community had lost an important opportunity.

while Ian Fry, representing the climate-vulnerable island nation Tuvalu said millions are already suffering the impacts of climate change

and that to deny this could be interpreted as a crime against humanity.
