New land-use-change emissions indicate a declining CO2 airborne fraction

About half of the anthropogenic CO2 emissions remain in the atmosphere and half are taken up by the land and ocean1. If the carbon uptake by land and ocean sinks becomes less efficient, for example, owing to warming oceans2 or thawing permafrost3, a larger fraction of anthropogenic emissions will remain in the atmosphere, accelerating climate change. Changes in the efficiency of the carbon sinks…

Soil degradation in the European Mediterranean region: Processes, status and consequences

The Mediterranean is the most susceptible region in Europe to soil degradation and desertification. •Multiple forms of physical, chemical and biological degradation affect the Mediterranean soils. •Some Mediterranean soils are reaching critical limits for its ability to provide ecosystem services. • A continuous and harmonised soil assessment is required to evaluate trends in…
