Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend

What are the most significant groups in this complex network of our emergent ‘collapse culture’? These groups don’t cohere into a single unified culture that understands itself as singular. Instead, the are thinly connected inside the complex of contemporary culture, a set of linked clusters. Between them, ideas do circulate, but the links between them, as I will return to, are more often established through intermixing in the heads of their proponents, however chaotically this takes place.....

The ocean ecosystem is a vital component of the global carbon cycle, storing enough carbon to keep atmospheric CO2 considerably lower than it would otherwise be. However, this conception is based on simple models, neglecting the coupled land-ocean feedback. Using an interactive Earth system model, we show that the role ocean biology plays in controlling atmospheric CO2 is more complex than previously thought. Atmospheric CO2 in a new equilibrium state after the biological pump is shut down increases by more than 50% (163 ppm), lower than expected as approximately half the carbon lost from the ocean is adsorbed by the land. The abiotic ocean is less capable of taking up anthropogenic carbon due to the warmer climate, an absent biological surface pCO2 deficit and a higher Revelle factor. Prioritizing research on and preserving marine ecosystem functioning would be crucial to mitigate climate change and the risks associated with it.

January 2025 was the 18th month in a 19-month period with a global-average surface air temperature exceeding 1.5ºC above pre-industrial levels. According to the Copernicus Climate Change Service…

2024 marks the first time since record keeping began that all of the 10 hottest years have fallen within the most recent decade.

New study shows low levels of future global warming are far less likely than previously thought. Very high warming is also slightly less likely.

Human-driven ocean warming is increasingly overwhelming El Niño, La Niña, and other natural climate patterns.

De voedselprijzen worden stevig opgedreven door maatregelen die de landbouw schoner moeten maken en moeten aanpassen aan een warmere wereld. Vooral arme landen zijn daarvan de dupe, blijkt uit nieuw onderzoek in Nature.

Le président libertarien se vante d’avoir réduit l’inflation et retrouvé l’équilibre financier du pays. Au prix pourtant d’une explosion de la précarité et du sacrifice des services publics, retrace la sociologue Maricel Rodriguez Blanco.

Human pressures have pushed the Earth system deep into the Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to the biophysical systems and processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing its emergence and mainstreaming across scientific disciplines and society. The nine PBs capture the key functions regulating the Earth system. The safe operating space has been transgressed for six of these. PB science is essential to prevent further Earth system risks and has sparked new research on the precision of safe boundaries. Human development within planetary boundaries defines sustainable development, informing advances in social sciences. Each PB translates to a finite budget that the world must operate within, requiring strengthened global governance. The PB framework has been adopted by businesses and informed
