United Nations, Sep 21 (IANS): The UK Prime Minister Boris Johnson has said that COP26 UN Climate Change Conference is "a turning point" for the world.

"I think the Glasgow COP26 is a turning point for the world. And it's the moment when we have to grow up and take our responsibilities," Johnson told reporters at the UN headquarters in New York following the closing of the Informal Leaders Roundtable on Climate Action, Xinhua news agency reported.

Calling on the rich countries to honour their pledge to provide each year $ 100 billion for the climate action in the developing countries, the Prime Minister said that "it is the developing world that is bearing the brunt of catastrophic climate change in the forms of hurricanes and fires and floods and the real long-term economic damage that they face."

"It's the developed world that over 200 years has put the carbon in the atmosphere that is causing this acceleration of climate change and, say, it really is up to us to help them," he added.

Earlier, Johnson told the roundtable that "history will judge" the world's richest nations if they fail to deliver on their pledge to commit $ 100 billion in annual climate aid ahead of COP26.

He placed the chances of securing the money before November at "six out of 10".

"We cannot let climate action become another victim of coronavirus. Let us be the leaders who secure the very health of te planet for our children, grandchildren and generations to come," Johnson said at the event.

He also assured his country "will lead by example, keeping the environment on the global agenda and serving as a launch pad for a global green industrial revolution."

However, he warned that "no one country can turn the tide, it would be akin to bailing out a liner with a single bucket."

The roundtable follows the recent report of the Intergovernmental Panel on Climate Change, signaling a "code red for humanity," and comes less than six weeks before the COP26 Climate Change Conference in Glasgow.

The roundtable addresses the gaps that remain on the actions urgently needed from national governments -- especially the G20 -- on mitigation, finance and adaptation.
