BERLIN, Feb 28 – Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released today.

The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.

Emerging ice-sheet modeling suggests once initiated, retreat of the Antarctic Ice Sheet (AIS) can continue for centuries. Unfortunately, the short observational record cannot resolve the tipping points, rate of change, and timescale of responses. Iceberg-rafted debris data from Iceberg Alley identify eight retreat phases after the Last Glacial Maximum that each destabilized the AIS within a decade, contributing to global sea-level rise for centuries to a millennium, which subsequently re-stabilized equally rapidly.

In Paris, all governments solemnly promised to come to COP26 with more ambitious 2030 commitments to close the massive 2030 emissions gap that was already evident in 2015. Three years later the IPCC Special Report on 1.5°C reinforced the scientific imperative, and earlier this year it called a climate “code red.” Now, at the midpoint of Glasgow, it is clear there is a massive credibility, action and commitment gap that casts a long and dark shadow of doubt over the net zero goals put forward by more than 140 countries, covering 90% of global emissions.

D’ici à 2030, les gouvernements prévoient de produire plus du double de la quantité d’énergies fossiles qui serait compatible avec la limitation du réchauffement climatique à 1,5 °C. L’écart entre le niveau de production d’énergies fossiles prévu par les États et le niveau de production compatible avec les objectifs de l’Accord de Paris est resté pratiquement inchangé depuis nos premières estimations en 2019.

As a leading climate scientist, Paola Arias doesn’t need to look far to see the world changing. Shifting rain patterns threaten water supplies in her home city of Medellín, Colombia, while rising sea levels endanger the country’s coastline. She isn’t confident that international leaders will slow global warming or that her own government can handle the expected fallout, such as mass migrations and civil unrest over rising inequality. With such an uncertain future, she thought hard several years ago about whether to have children.

« Trois décennies d'atténuation du changement climatique : pourquoi n'avons-nous pas infléchi la courbe des émissions mondiales ? ». C’est le titre d’un papier de recherche rendu public il y a quelques jours, qui mérite l’attention.
