Africa"s carbon sink capacity is shrinking
The population of Africa, the second-largest continent in the world, currently sits at about 1.4 billion, but is set to exceed 2 billion by 2040. This means greater swaths of land than ever before are being used for agriculture, and livestock numbers.....»»
A new estimate of US soil organic carbon to improve Earth system models
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate.....»»
