TS.B.1.5 Climate change is affecting ecosystem services connected to human health, livelihoods and well-being . In terrestrial ecosystems, carbon uptake services linked to CO₂ fertilisation effects are being increasingly limited by drought and warming and exacerbated by non-climatic anthropogenic impacts . Deforestation, draining and burning of peatlands and tropical forests and thawing of Arctic permafrost have already shifted some areas from being carbon sinks to carbon sources . The severity and outbreak extent of forest insect pests increased in several regions . Woody plant expansion into grasslands and savannahs, linked to increased CO₂, has reduced grazing land, while invasive grasses in semiarid lands increased the risk of fire . Coastal blue carbon' systems are already impacted by multiple climate and nonclimate drivers . Warming and CO₂ fertilisation have altered coastal ecosystem biodiversity, making carbon storage or release regionally variable .
