“Unprecedented” stakes in the fight against climate change: IPCC Head

Just last year, the world experienced a chain of deadly and unprecedented floods, heat waves and wildfires on four continents.

The United Nations Head of Climate Science said Monday that stakes in the fight against global warming are higher than ever.


“Necessity of Working Group 2 Report Lee Fe-sung, chairman of the Intergovernmental Panel on Climate Change (IPCC), said in a live video cast.

Species extinction, ecosystem collapse, mosquito-borne diseases, deadly heat, water scarcity and reduced yields are already significantly exacerbated by rising temperatures.

Just last year, the world experienced an unprecedented cascade of floods, heat waves and wildfires on four continents.

All of these effects will accelerate in the coming decades, even if the carbon pollution that causes climate change recovers rapidly, the IPCC report could warn.

An important 40-page summary for policy makers — extracting the underlying chapters for a total of thousands of pages and reviewing each row — will be published on February 28th.

Rachel Cleetus, Director of Climate and Energy Policy at the Union of Concerned Scientists, said:

“This isn’t just a more scientific prediction of the future,” she told AFP before the two-week plenary.This is about Extreme event And the late disasters that people are experiencing now. “

The report also highlights the urgent need for “adaptation,” according to an early draft seen by AFP in 2021. This means preparing for the catastrophic consequences that are no longer inevitable.

In some cases, this is an unbearably hot day, flash floods, Storm surge It’s a matter of life and death.

Impact of climate change

Impact of climate change.

“Doping the atmosphere”

“Growth Climate impact Inger Andersen, Head of the United Nations Environment Program, points out that climate change can be a major driver of species loss and goes far beyond our efforts to adapt to them. ..

The IPCC assessment (sixth since 1990) is divided into three sections, each with its own “working group” of hundreds of scientists.

In August 2021, the first article in the physical sciences found that it was almost certain that global heating would probably exceed 1.5 degrees Celsius (2.7 degrees Fahrenheit) within 10 years.

The surface of the earth has warmed 1.1 degrees Celsius since the 19th century.

“We have been doping the atmosphere Fossil fuel“World Meteorological Organization Chief Petterita Alas said on Monday comparing the results with the” enhanced performance “of Olympic athletes who used banned substances.

The 2015 Paris Agreement requires global warming to be “well below” 2 ° C, ideally 1.5 ° C.

This report definitely reinforces this more ambitious goal.

Similarly, highlight that vulnerability Abnormal weatherAccording to the draft seen by AFP, even if it is exacerbated by global warming, it can be reduced by better planning and preparation.

This isn’t just for developing countries, said Friederike Otto, a professor at Imperial College, who said a massive flood in Germany last year killed dozens of people and caused billions of damage. did.

Those who are least responsible for climate change are those who suffer the most from their effects.

The people who are least responsible for climate change are those who are most suffering from the effects.

Turning point

“In a densely populated area, even without global warming, it would have been a heavy rain that flooded the river very easily,” quantifying the extent to which climate change makes extreme weather more likely or severe. Otto, a pioneer in science, said. ..

The report focuses on how climate change is widening the already yawning inequality gap, both interregional and national.

The simple fact is that those who are least responsible for climate change are those who suffer the most from their effects.

The report may also highlight dangerous “turning points”, invisible temperature trip wires. climate A system for irreversible and potentially catastrophic change.

Some of them (such as the melting of permafrost, which contains twice as much carbon in the atmosphere) can be fueled. Global warming All by yourself.

Professor Edward Carr of Clark University, the lead author of a chapter in the report, said:

“We are late waiting every day, but some of those options get harder or harder.”
