Climate change could erase most South American cloud forests, study warns
Cloud forests — among the most biodiverse ecosystems on Earth — face near-total collapse across South America if greenhouse gas emissions continue on their current trajectory, according to new research. The study finds that rising temperatures will push the low-hanging clouds that define these habitats to higher elevations, effectively eliminating the cool, moisture-rich conditions thousands of species depend on. The findings add urgency to emissions reduction efforts, as the loss of these forests would represent an irreversible blow to global biodiversity.

The world’s great deltas are sinking — and with them, a global food system
The world's major river deltas — including the Mekong, Nile, and Mississippi — are sinking faster than sea levels are rising, threatening the homes of hundreds of millions of people. The crisis is driven by a combination of groundwater extraction, upstream dams blocking sediment flow, and climate change accelerating coastal erosion. At stake is not just human displacement, but the agricultural heartlands that feed much of the planet.

Deforestation and warming could push Amazon to tipping point by 2040s: Study
The Amazon Rainforest could reach an irreversible tipping point as early as the 2040s, according to new research published in Nature. The study finds that deforestation of just 22-28% of the forest, combined with 1.5-1.9°C of global warming, could trigger a catastrophic collapse — thresholds alarmingly within reach given current trends. The findings compress the timeline for action significantly, raising urgent questions about the adequacy of existing conservation and climate commitments.

Trump’s Iran war may stymie climate gains with boost to big oil, experts say
War-driven oil windfalls are handing the fossil fuel industry a financial and political lifeline at a critical moment for climate progress. Experts warn that surging profits will fund expanded drilling operations and supercharge lobbying efforts to entrench Trump-era regulatory rollbacks. The result could be a self-reinforcing cycle that delays the clean-energy transition well beyond the current administration.

Why Fears Are Growing Over the Fate of a Key Atlantic Current
The Atlantic Meridional Overturning Circulation, a massive ocean current system that regulates temperatures across northern Europe and beyond, is showing warning signs that alarm climate scientists. Mounting research suggests the system may be approaching a tipping point, with its collapse potentially triggering dramatic shifts in global weather patterns. The stakes are high — and while the science remains unsettled, the trend lines are difficult to ignore.
