Chart of the day: Scientists slam emissions reduction "flatline," say warming overshoot imminent
The world's carbon emissions will be slightly lower than 2025 but you have to squint to see the difference.

Les émissions de CO₂ de Google et d’Amazon bondissent, propulsées par l’essor de l’IA
Les émissions totales de Google ont augmenté de 82 % depuis 2019 alors que le groupe s’était engagé à les réduire de moitié d’ici à 2030. Celles d’Amazon ont grimpé de 58 % au cours de la même période, malgré une neutralité carbone promise pour 2040.
Sans eau, les forêts arrêtent de capter du CO₂
Pour survivre en période de sécheresse, les arbres stoppent la photosynthèse, une activité très gourmande en eau. Des forêts entières se retrouvent ainsi à émettre plus de CO₂ qu’elles n’en capturent.

The story of CO2 is the story of everything: how carbon dioxide made our world
"How carbon dioxide, the world's most important substance, shaped the planet's past and present-and holds the key to our future Carbon dioxide: this seemingly simple and ubiquitous substance is fundamental to how our planet works. All life is made from CO2, and its behavior on this planet has kept Earth bizarrely habitable for hundreds of millions of years. In its workings lie both the splendor of our world and the potential for life's destruction. In short, it is the most important substance in history. But why is CO2 as essential to life on Earth as it is capable of destroying it? In The Story of CO2 Is the Story of Everything, award-winning science journalist Peter Brannen reveals carbon dioxide's fundamental role in the operation and maintenance of our planet. Starting at the beginning of time and working all the way up to our present reality, he illuminates how CO2 has been responsible for the planet's many deaths and rebirths, the evolution of life, and the development of modern human society. Carbon dioxide's movement through rocks, air, oceans, and life has kept our planet's climate livable, its air breathable, and its oceans hospitable to complex life for more than five hundred million years. And only by understanding CO2 in the context of deep Earth history can we see how it gave rise to today's industrial economy-and more clearly recognize what it means to be churning through hundreds of millions of years of old life in the form of fossil fuels and converting it all to carbon dioxide. With groundbreaking research and a clear-eyed perspective, Brannen shows how a deep exploration into the mechanics of the carbon cycle and the history of our planet can provide hope for averting environmental catastrophe in the future. It all starts with a richer understanding of the essential role of one substance"--
The Graph That Should Be Front-Page News
Every so often the Earth produces a signal that is impossible to ignore. This graph is one of them. It shows sea-surface temperatures in the Niño 3.4 region of the equatorial Pacific, one of the most important parts of the Earth's climate system. Each blue line represents a different year since 1982. The red line is this year. It doesn't just set a new record. It has departed entirely from the range of previous observations.If this graph represented stock market prices, a new Olympic record or a

Climate change presents an existential threat to humanity. We are already seeing the effects and they are showing up faster and stronger than anticipated. A report by United Nations' scientific panel on climate change released this month expects the atmosphere-on our current trajectory-to warm up by 1.5 degrees Celsius by 2040. Even the effects of a 0.5 degrees increase will have far-reaching consequences. This research indicates that we are already past the tipping point; even if we significantly reduced emissions, climate change would continue (Source IPCC summary C3 section). We believe there's still time to make a change if we look both to renewal energy and CO2 removal.
