The effects of warming are now generalized and often irreversible, alert the researchers. Adapting to new living conditions is essential, but the world will be more and more confronted with damage to which it is impossible to remedy.

Humanity and nature are at risk. Every day more, they are pushed to their limits, even beyond, by the uncomfortable impacts, generalized and often irreversible of climate change of human origin. These effects, which already affect the lives of billions of humans, will accelerate whatever the pace of reduction of greenhouse gas emissions. They will strike companies intolerablely, multiplying threats to food production, water supply, human health, coastal infrastructure, national economies and survival of a large part of the natural world.
With, at the key, even more shortages, poverty, famines or conflict. Without urgent measures to limit the increase of the thermometer to 1.5 ° C in relation to the pre-industrial era, adaptation to climate change will become more expensive, limited and, in some cases, simply impossible.
This dark assessment is drawn up by the Intergovernmental Panel on Climate Change (IPCC), Monday, February 28, in the 2 e part of its sixth evaluation report. After a first component published in August 2021 on the physical basis of climate change, this time, this time, bent on impacts, vulnerabilities and adaptation to the climate crisis. She will then publish a 3 e in April, devoted to solutions to reduce greenhouse gas emissions, before a summary synthesis for September.
The new report, written by 270 scientists from around the world from the analysis of 34,000 studies, is much more alarming than the previous one that dated 2014. If it shows a major alert for governments. It may, however, see its limited scope, while the eyes are riveted on the warming war in Ukraine. “Ukrainian researchers have remained involved throughout the work and told us that the best IPCC could do is to continue its work,” says Wolfgang Cramer, Research Director (CNRS) at the Mediterranean Institute. biodiversity and marine and mainland ecology (Imbe), and one of the authors of the report.
The summary for decision-makers, negotiated for two weeks by the representatives of the 195 IPCC member countries, in collaboration with the authors who maintain the last word, was completed with the delay in particular because “certain countries wanted that the message is diminished, “says Cramer. Scientists have held good.
