Climate change: a dramatic introductory UN report | Experts from the international organization are of the opinion that it will be necessary to “adapt” to the “devastating consequences”

Husung Lee, chair of the UN’s Intergovernmental Panel on Climate Change (IPCC), warned in a big way on Monday during the start of the meetings, that “people will have to adapt to face the devastating and inevitable consequences of global warming.” The devastating impact of this phenomenon on the environment and the urgent measures that governments need to take to mitigate the climate catastrophe.

The head of the UN panel of experts said that “there was never much at stake and the fight against climate change was greater than ever”, so they would meet over the next two weeks to analyze and prepare the second part of the report. Specific to the effects of global warming.

Although the Intergovernmental Panel on Climate Change has been warning about the dire consequences of global warming for many years, what is new in this latest report is that it focuses on adaptation: Climate change will have a devastating and inevitable impact on Earth and people will have no other choice to adapt to this scenario. the new.

From the meetings starting on Monday, in which 195 countries are participating, will emerge a 40-page document to be published on Feb. 28, which will “integrate more closely the economic and social sciences and contribute to those responsible for public policy makers. Knowledge helps them formulate policies and take action,” Hosung Lee said. decisions”.


One of the authors of the first report, climatologist Laurent Pope, warned that “in certain regions, if temperatures exceed very high levels, human life would not be possible.”

In the said document, published last August, experts of the Intergovernmental Panel on Climate Change estimated that by 2030, ten years earlier than expected, the global temperature will rise by 1.5 degrees Celsius.

The second chapter of the report warns of the inevitable consequences of global warming and highlights that the way to deal with it will be adaptation.

The third part, due in April, will focus on solutions to reduce greenhouse gas emissions.

Obvious consequences

After more than a century and a half of economic development based on fossil fuels, the planet’s temperature has risen by 1.1°C since the pre-industrial era, resulting in a doubling of dog days, droughts, and devastating storms and floods.

Species extinction, ecosystem collapse, mosquito-borne diseases, deadly heat waves, droughts, and reduced yields are already tangible consequences of rising temperatures.

On almost every continent, the world suffers from catastrophes, such as last year’s fires in the western United States, Greece or Turkey, floods that affected Germany or China, and a temperature close to 50 degrees Celsius in Canada.

The head of the World Meteorological Organization (WMO) added that “about 4.5 billion people have experienced a climate-related disaster in the past 20 years,” noting that fossil fuels “caused” the erosion of the atmosphere, which is fueling global warming. impact.

The consequences of global warming will affect all continents and all aspects: health, food security, water scarcity, population displacement, and the destruction of ecosystems.

The need for urgent measures

However, Inger Andersen, Director of the United Nations Environment Program (UNEP), said that “increasing climate impacts far outweigh our efforts to adapt.”

For Andersen, the world is already aware of the scientific findings that UN experts present each year and decade to decade, but he stressed that “recognizing the evidence is only the first step.”

Faced with the need to reduce emissions of heat-trapping gases by 2030 – by nearly 50% – in order not to exceed the +1.5°C limit for global temperature, the scientist committed at COP26 in Glasgow, last November, to accelerate the fight against global warming.

But the UN Secretary-General, Antonio Guterres, called the initiative “insufficient” to postpone the “climate catastrophe that continues to knock on the door”.

Meanwhile, the co-chair of the UN Panel of Experts, Debra Roberts, stressed that this second report is not “just a list of things that can be done, but also an assessment of the effectiveness and feasibility” of the actions.
