Cost of environmental damage will be six times higher than price of limiting global heating to 2C, study finds
If the anomaly does not stabilise by August, ‘the world will be in uncharted territory’, says climate expert
Collapse in system of currents that helps regulate global climate would be at such speed that adaptation would be impossible
Rapid ocean warming and unusually hot winter days recorded as human-made global heating combines with El Niño
Existing production destroys more value than it creates due to medical and environmental costs, researchers say
Population likely to peak sooner and lower than expected with beneficial results – but environment is priority
Extreme weather is ‘smacking us in the face’ with worse to come, but a ‘tiny window’ of hope remains, say leading climate scientists
Human-caused climate disruption and El Niño push temperature in mountains to 37C
Amazon rainforest and other ecosystems could collapse ‘very soon’, researchers warn
Going beyond climate disruption, the report by the Earth Commission group of scientists presents disturbing evidence that our planet faces growing crises of water availability, nutrient loading, ecosystem maintenance and aerosol pollution. These pose threats to the stability of life-support systems and worsen social equality.
The author and eminent climate scientist on the deniers’ new tactics and why positive change feels closer than it has done in 20 years
The United States and Saudi Arabia have hamstrung global efforts to scrutinise climate geoengineering in order to benefit their fossil fuel industries, according to multiple sources at the United Nations environment assembly, taking place this week in Nairobi.
Lucrative pay and share options have created an incentive for oil company executives to resist climate action, according to a study that casts doubt on recent net-zero commitments by BP and Shell. Compensation packages for CEOs, often in excess of $10m (£7.2m), are linked to continued extraction of fossil fuels, exploration of new fields and the promotion of strong market demand through advertising, lobbying and government subsidies, the report says.
Sustainable food systems are a cornerstone to cutting emissions but have been largely absent from the agenda in Glasgow. Farming is a complex issue on the journey to net zero, as it is both a source and sink for emissions. About 20% of global emissions come from agriculture and land use, and this rises to more than 25% for the food system as a whole, which includes processing, packaging and transport.
The scientific consensus that humans are altering the climate has passed 99.9%, according to research that strengthens the case for global action at the Cop26 summit in Glasgow.
Beware summer! The season we used to anticipate as the lightest, brightest, balmiest time of the year now comes with a health warning.
After water, concrete is the most widely used substance on Earth. If the cement industry were a country, it would be the third largest carbon dioxide emitter in the world with up to 2.8bn tonnes, surpassed only by China and the US. The material is the foundation of modern development. Concrete is how we try to tame nature...
