1/3 Using the global wetland model ensemble of the Global Carbon Project-Global Methane Budget, constrained by 163 site-year measurements, Zhen Zhang, @benpoulter.bsky.social & colleagues show that for every 1 degree C increase in global temperature, CH4 emissions increase by 24Tg per year

Rice feeds billions of people – but its role in fueling climate change is growing
There are ways to reduce emissions without sacrificing yield. A new study shows how, and looks at a technique billed as ‘climate-friendly’ that makes emissions worse.
