Ancient climate data suggests Arctic winter sea ice loss could outpace projections

Researchers have used climate information preserved in ancient ocean sediments to reassess projections of Arctic winter sea ice loss. By comparing sediment records from 6,000 years ago with modern climate models, they found that projected winter ice coverage may be about one million square kilometers smaller than previously estimated.

Arizona attorney general challenges expansion of AI data centers

Arizona’s attorney general has escalated the political opposition to data-center expansion, arguing that the state does not need 50 additional facilities. The stance, highlighted by Politico, frames AI infrastructure growth as an issue warranting greater scrutiny rather than automatic development. The statement places data centers at the center

Oil Spills Continue to Damage Deep Ocean Habitats a Decade Later

Oil spills may have effects on deep-ocean ecosystems that persist long after the visible slick has disappeared. Although oil is commonly understood to float, new research suggests that it can gradually permeate even extremely deep marine habitats. The study found that animal populations in affected areas can decline by

Switzerland Loses Nearly 20% of Glacier Ice in Five Years

Switzerland’s glaciers are undergoing a rapid decline, losing more than 5% of their ice volume in 2026 alone. Over the past five years, nearly 20% of the country’s glacier ice has disappeared. The losses have affected some of Switzerland’s best-known glaciers, which experienced their worst melting

UN Sees 1.5°C Warming Being Overshot, Shifts Focus to Adaptation and Carbon Removal

The UN now assesses that global warming is likely to move beyond the 1.5°C threshold. According to its new outlook, the best-case pathway would involve an overshoot to 1.8°C, accompanied by massive efforts to remove carbon from the atmosphere. This assessment shifts the policy question

Drought Fuels Widespread Fires in New Guinea

NASA observations show unusually high emissions on both sides of New Guinea, indicating widespread burning across the island. The fires are human-set and are spreading through a landscape parched by drought. The event highlights how drought and human ignition can combine to produce broad, intense fire activity, although the

Data Center Expansion Could Reverse Decades of Air Quality Gains in Texas

Texas is becoming a major center for the physical infrastructure supporting generative AI, with new and proposed data centers driving unusually high electricity demand. The environmental consequences will depend heavily on how that demand is met. Developers and utilities are considering gas turbines, renewable energy, and new power sources built
