"... This goal of $100 billion is a meagre amount in size in contrast to the actual needs assessed for developing countries in trillions of dollars", it says, adding that even a simple adding up of all the requirements of developing countries mentioned in their climate action plans submitted to the United Nations climate body came to around $4.4 trillion.
Two weeks of talks began yesterday in Poland to tackle deep political divisions at the most important United Nations meeting on global warming since the landmark 2015 Paris deal to shift away from fossil fuels.
Almost 200 nations gathered in Poland Monday for the start of the COP24 summit, where they must agree on a universal rulebook to make good on the promises they made in the 2015 Paris climate deal.
Also on Monday, Polish President Andrzej Duda presented the Silesian Declaration on Solidarity and Just Transition, a document that calls for a "decent future" for workers affected by the transition away from fossil fuel industries.
"We are here to enable the world to act together on climate change", he said.
But the rate of climate change is rapidly outstripping mankind's response.
With further meetings next year meant to build on what's decided in Katowice, he urged all countries to "show creativity and flexibility".
Meeting the commitments of the 2015 Paris climate agreement could save millions of lives and hundreds of billions of dollars by the middle of the century, according to the report. The only holdout was the United States.
Citing a recent scientific report on the dire consequences of letting average global temperatures rise beyond 1.5 degrees, Guterres urged countries to cut their emissions by 45 per cent from 2010 levels by 2030 and aim for net zero emissions by 2050.
"The rest of the G-20 have not only understood the science, they are taking actions to both prevent the major impacts and strengthen their economies", said Figueres, who now works with Mission 2020, a group that campaigns to reduce greenhouse gas emissions.
"We feel as if we have been penalised for the mistakes we never made", said Bhandari.
Negotiators are also expected to put forth plans to help developing nations adapt to a warming climate.
Such cuts, which experts say are the only way to achieve the 1.5-degree goal, would require a radical overhaul of the global economy and a move away from using fossil fuels.
"The good news is that we do know a lot of what we need to be able to do to get there", said David Waskow of the World Resources Institute.
A 15-year-old Swedish activist who takes time out of school to highlight the danger of global warming echoed his appeal. sentiment. old Greta Thunberg said world leaders who skip the climate summit are "very irresponsible".
Katowice is at the heart of Poland's coal mining region of Silesia and there are still several active mines in and around the city.
"The world is at a crossroads and decisive action in the next two years will be crucial to tackle these urgent threats", they said in the joint statement. "It's what I think you could call a distributed leadership, where you have a number of countries - some of them small or medium-sized - really making headway and doing it in tandem with cities and states and businesses".
Not far from the COP24 venue in Katowice, Polish anti-coal campaigners held their own, smaller protest on Sunday. Thousands of people marched Saturday in Berlin and Cologne to demand that Germany speed up its exit from coal-fired power plants. "This reality is telling us that we need to much more", she said Sunday.
