Reducing sulphur in the air may inadvertently increase natural emissions of methane from wetlands such as peatlands and swamps, a new study publishing in Science Advances has found. The resulting additional future release of 20-34 million tonnes of methane each year from natural wetlands would mean targets to reduce human-caused emissions need to be more stringent than currently set out in the Global Methane Pledge.

A new study published in Nature Energy reveals that a combination of electrification, improved energy efficiency, and smarter energy use can significantly reduce greenhouse gas emissions in buildings and transport—two sectors that together account for 58% of global energy consumption and 26% of global emissions. Researchers, including from CMCC, show that these reductions are achievable with existing technologies, offering a clear and practical roadmap for policymakers and industry leaders, in line with the global goal of limiting warming to 1.5°C.

As the world works to meet net-zero carbon goals, a new study offers a critical reminder: precision matters. The researchers suggest refining how we assess a natural carbon storage strategy to ensure the technology lives up to its potential as a climate change solution.

Computer models reveal how human-driven climate change will dramatically overhaul critical nutrient cycles in the ocean. In the Proceedings of the National Academy of Sciences, University of California, Irvine researchers report evidence that marine nutrient cycles – essential for sustaining ocean ecosystems – are changing in unexpected ways as the planet continues to warm.

New assessment warns area the size of the USA will become too hot during extreme heat events for even healthy young humans to maintain a safe body temperature if we hit 2°C above preindustrial levels.

For those aged over 60, the same 2°C rise would see more than a third of the planet’s land mass cross this critical ‘overheating’ threshold
