A greenhouse gas essential to life, and a marker of climate change.
A new UK edition dissects the 1979-80 Tehran upheaval through a spy-woven lens, detailing the Kuzichkin-McCredie dynamics, Soviet-Iranian covert games, and the unintended consequences of Western espionage as the Islamic Republic rises.
Scientists have found macromolecular carbon in Martian mudstones, suggesting habitable conditions billions of years ago. The carbon could be biogenic or abiotic; samples will return to Earth for definitive testing, with timelines running 2035–2039. This marks multiple robust organic detections across Jezero crater and Gale crater.
Europe endures a record heat wave tied to climate change as France faces rising deaths. Only ~20% of European homes have air conditioning, compared with ~90% in the U.S., highlighting a widening cooling gap and policy tensions across the continent.
Wildfires across Canada have intensified this summer, with thousands evacuated and millions of hectares burned. Fire seasons are surging due to warmer, drier conditions, while governments mobilize crews and resources to combat the blazes and protect communities.
News analysis tracks the new prime minister’s approach, reflecting Compass proposals for the first 100 days and comments from senior Labour figures on leadership style and policy delivery.
Scientists reconstruct ancient forests using fossil leaf cuticles to show canopy loss during the Paleocene-Eocene Thermal Maximum, revealing how forests thin, then recover slowly—an event linked to today’s rapid CO2 rise and warming.
The UN Environment Programme has published a report concluding the world will likely exceed the Paris 1.5°C limit within years. UNEP recommends an "overshoot, peak and decline" pathway that combines immediate, deep emissions cuts, rapid methane reductions and carefully governed carbon dioxide removal to return temperatures below 1.5°C this century.
The Environmental Protection Agency has repealed the main carbon-emission limits on power plants and is proposing to remove all remaining greenhouse-gas rules for the sector. The move, argued to lower energy prices, faces immediate challenges from public-health groups and critics who say it undermines climate protections.
