Climate, at the start in Madrid the Cop25: present 196 countries | The UN: "Point of no return ever closer"

"Insufficient efforts" "For decades, man has been at war with the planet and the planet is giving us back blow by blow. We must end our war against nature and science tells us we can do it," Guterres warned. spoke of "totally insufficient" efforts to reduce greenhouse gas emissions so far.

2019 among the hottest five years Anticipating a report from the World Meteorological Organization, Guterres confirmed that, without surprises, 2019 will be among the warmest five years. "The last five years have been the hottest ever recorded," he said, listing the devastating and increasingly lethal effects of global warming: rising sea levels, melting polar ice caps, and drought.

Temperatures, carbonic neutrality and greenhouse gases To keep climate change within manageable limits, countries should limit global temperature increases to 1.5 degrees, achieve carbon neutrality by 2050 and reduce greenhouse gas emissions by 45% compared to 2010 levels by 2030. "What is still lacking is the political will", is the thrust of Guterres, which has however kept the "hope" open. A hope linked to mass mobilizations, such as those of "Fridays for future" by Greta Thunberg. Within the next year the new national climate action plans will have to be presented; the UN expects them to be ambitious in order to reach the temperature targets set by the Paris agreement.
