Climate change puts Europe’s last peatlands at risk

,
Currently, a study has found, only 7% of continental peatlands can be considered intact. But climate pressure is increasing, and in the coming years the situation could worsen

Here’s how Arctic soil offsets emissions from alpine permafrost

,
Climate change reduces the absorption of greenhouse gases by alpine permafrost but, at the same time, it stimulates CO2 and methane sequestration in Arctic frozen soil, a Chinese study has found. In the first case, global warming potential increases by 13%. In the second, it decreases by 10%

An integrated approach is needed for EU soil quality monitoring

,
A new study reviews different soil assessment schemes. The “binary” system is the most suitable for macro evaluation. But tools for local investigations are also needed

Chinese researchers propose a new indicator to assess soil carbon stability

,
Research conducted by the Beijing Academy of Sciences has defined a new framework for assessing the Microbial Carbon Pump in soil. It distinguishes between stable and non stable organic matter (that is more easily decomposed and released)

Human activity causes carbon loss in deserts

,
Some human-induced disturbances cause significant carbon loss in the soil of hyper-arid environments, a Chinese study claims. Among the most impactful activities even some practices considered “sustainable” such as seasonal harvesting and irrigation

Carbon balance in Amazon rainforest shows 370 million tons deficit in a decade

,
Between 2010 and 2020, carbon losses increased due to deforestation and other underestimated phenomena such as fires and fragmentation, according to new study. Emission intensity is higher in protected areas

A Chinese study has quantified 20 years of carbon sequestration in wetlands

,
Research by the Chinese Academy of Sciences reveals that wetlands sequestered an average of one billion tons of carbon per year in the first two decades of the century. Seventy percent of this capture takes place in tropical areas

In the Amazon region post-fire stress can last in forests for decades

,
NASA research shows that forests in the region affected by fires remain warmer than normal for at least 30 years. This has obvious consequences for their carbon storage and climate mitigation capacity
