Africa: Rising Co₂ Is Making African Savanna Grasses Grow More – What This Means for Grazing, Fire and Carbon Storage
Plants use carbon dioxide (CO₂) in photosynthesis to make the carbohydrates they need to grow. As the CO₂ in the atmosphere rises, mainly because humans are burning fossil fuels, many plants can photosynthesise more or use water more efficiently. This is known as “CO₂ fertilisation”. Scientists have carried out numerous studies into CO₂ fertilisation in…
