Climate activists attend the March for Climate in a protest against global warming in Katowice, Poland, Saturday, Dec. 8, 2018, as the COP24 UN Climate Change Conference takes place in the city.

As the U.N. global climate conference in Katowice, Poland entered its second week Sunday, the non-governmental environmental organization Greenpeace demanded urgent action from world leaders to tackle climate change.

Greenpeace activists projected a message onto the roof of the "Spodek" arena where the COP24 is being held, saying “No Hope Without Climate Action: and "Politicians Talk, Leaders Act."

Disappointing many of the scientists and delegates at the conference, the United States, Russia, Saudi Arabia and Kuwait refused to endorse a landmark study on global warming which was to be the benchmark for future action in curbing the global warming.

The four nations wanted only to “note" but not "welcome" the report of the Intergovernmental Panel on Climate Change that was released in October, in keeping with the views of the Trump administration. With no consensus on including the report, the idea was dropped.

U.S. President Donald Trump, who has announced he is pulling the United States out of the Paris climate agreement, tweeted Saturday that "people do not want to pay large sums of money ... in order to maybe protect the environment.'' 

The IPCC’ report said that drastic actions would be needed to achieve the Paris accord's most ambitious target of keeping global warming below 1.5 degrees Celsius. The report warned that the world was far from that target and heading more towards an increase of 3 degrees Celsius.

On Monday, the environmental ministers arrive at COP24 and many delegates hope that they will make every effort to include the IPCC report in the conference agenda.
