Strong message from Greta Thunberg to thousands of protesters 1:11
(CNN Spanish) -
The "window" to limit global warming to a range that allows avoiding the worst effects of rising temperatures remains open, said this Friday the secretary general of the Intergovernmental Panel of Experts on Climate Change (IPCC, for Abdalah Mokssit, but countries cannot act "slowly" if they want to achieve the goal.
"The window remains open for the 1.5 degree Celsius to 2 degree Celsius range (of rising temperatures) to be considered. This is rapidly undergoing a change that requires immediate unprecedented action for us to avoid global chaos. The door is still open and the window is still open, but we cannot act slowly, "said the expert in an interview with Carmen Aristegui, while COP26 was taking place in Glasgow.
The IPCC published a key report on climate change in August, which concludes that the planet has already warmed 1.1 degrees Celsius from pre-industrial levels and that there is no longer any doubt about man's role.
"We have known for decades that the world is warming, but recently we have changes that show that each decade brings records, record numbers, decade after decade we have a warming that is greater than the previous one," said the expert when analyzing the conclusions of that report, a key input for decision makers.

In addition, Mokssit indicated that "there is not a corner of the world, a part of the world that is free from these extreme events" and warned that there are some events in which there is no "going back" possible.

"We have the ability to stop some of the very, very difficult impacts of climate change. But it will also be important, really important, to deal with what is irreversible."
This Thursday, the UN released its report on the "adaptation gap" to climate change, which shows that the estimated costs of adapting to the worst effects of rising temperatures in low-income countries are five to 10 times greater than the money. that is reaching those regions.

Is there hope at COP26?
This Friday, thousands of young people took to the streets in Glasgow to demand that world leaders take action to address the crisis.
At the march organized by the Fridays For Future movement, activist Greta Thunberg called COP26 a "failure".
Mokssit highlighted the role of young people, who are aware of climate change and can "provide help to avoid a negative impact on the youth of the next generation."

When asked whether he believes that the necessary agreements can be reached at the summit, the IPCC Secretary General replied: "A thorough understanding of the message from the scientists gives us hope that there will be a mobilization and a declaration at the level of what to be expected ".
And he remarked: "Now there is no discussion, there is no ambiguity, there is no doubt about it. (...) Ambition must seriously grow to stay on the path of (limiting the increase in temperatures to) 1.5 degrees Celsius."
He also warned: "If we don't take action, this is really going to compromise the lives of future generations."
