The 2026 assessment found record transgression in climate, biosphere, land, freshwater, nutrient flows, novel entities and ocean acidification. The framework measures rising systemic risk; it sets no single collapse date and does not say every change is irreversible.
A University of Arizona-led study projects canopy temperature will rise about 0.11°C more than air temperature by the end of the century. The gap could reduce photosynthesis and transpiration, alter rainfall and accelerate warming unless models include the heat plants actually experience.
An international research team has revealed that the Araucaria forest on the southern Brazilian plateau, one of the world's most unique ecosystems, was shaped over the last 6,000 years by the interaction between climate change and the management practices of the Southern Jê Indigenous peoples. The study underscores the importance of integrating ancestral knowledge into current conservation strategies.
The World Meteorological Organization’s regional climate report recorded high temperatures, marine heatwaves and historically low surface pH levels in 2025. The impacts extend to ecosystems, fisheries, economies and communities, while coordination and capacity gaps still hinder risk anticipation.
