The world is "way off course" in its plan to prevent catastrophic climate change, the United Nations warned Monday as nations gathered in Poland to chart a way for mankind to avert runaway global warming.
"Right now we are facing a man-made disaster of global scale, our greatest threat in thousands of years: Climate change", Attenborough said as the worldwide climate conference got underway with talks on how countries will implement the 2015 Paris Agreement limiting carbon emissions. "Time is running out".
"They're supporting you in making tough decisions but they're also willing to make sacrifices in their daily lives".
After a string of damning scientific reports showing humanity must drastically slash its greenhouse gas emissions within the next decade, UN Secretary-General Antonio Guterres told delegates at the opening of a UN climate summit: "We are still not doing enough, nor moving fast enough". "The continuation of our civilizations and the natural world on which we depend is in your hands".
Mr Guterres, who spoke at the opening of the conference, called climate change, "the most important issue we face".
The summit taking place December 2-14 in Katowice is meant to build on the 2015 Paris climate accord, which set a goal of limiting global warming to well below 2 degrees Celsius (3.6 degrees Fahrenheit) by the end of the century.
In Paris three years ago, nations committed to limit global temperature rises to well below 2 degrees Celsius, and to the safer cap of 1.5 C if possible.
The 92-year-old naturalist addressed the delegates from more than 200 nations in Katowice, as teams work to find ways to ensure implementation of the historic 2016 Paris Climate agreement that seeks to slash global greenhouse emissions from 2020.
Belgium's liberal Prime Minister Charles Michel called the march "a formidable success" and promised to defend "ambitious targets" at the two week-long United Nations climate change summit which opened on Sunday in the Polish city of Katowice.
But many other countries are already dealing with the droughts, higher seas and catastrophic storms climate change is exacerbating right now.
A process to enable countries to announce efforts by 2020 to ramp up their domestic ambition on cutting greenhouse gas emissions must be launched, they said, as current efforts are not enough to prevent risky temperature rises.
"The world is at a crossroads and decisive action in the next two years will be crucial to tackle these urgent threats".
G20 leaders on Saturday agreed a final communique after their summit in Buenos Aires, declaring that the Paris Agreement was "irreversible".
The devastating impacts of climate change are outweighing the initiatives to accelerate action against climate.
The UN chief thanked Modi for his commitment to increase India's nationally determined contributions to the Paris Agreement.
The Netherlands, a country with a long history of pumping oil and gas from the ground, is also among the places most at risk from rising sea levels caused by global warming.
Referring to the Intergovernmental Panel on Climate Change's (IPCC) special report, released in October 2018, on the impacts of the global warming of 1.5°C, Mr. Endalew said, the IPCC report made it crystal clear that every bit of warming mattered, especially for the LDCs. "So I think it is perfectly normal that his Holiness the Pope, not only this Pope, it comes from the past, have a very positive position in relation to climate action", he said.
