Amazon understory forests show short-term boost in CO₂ uptake – but this comes at a cost
Tropical forests are one of the planet's most important carbon sinks – often also called "the lungs of the Earth". But their future in a high-CO₂ world remains uncertain. IIASA researchers contributed to a new study, which suggests even small understory trees in the Amazon may initially buffer climate change more strongly. Their long-term capacity to store carbon could, however, be restricted by nutrient availability, highlighting the vulnerability of these ecosystems under future climate conditions.
