Why in news
A study in Nature Climate Change highlights that higher tree species richness accelerates carbon absorption, emphasizing biodiversity's role in climate mitigation.
Background
The study analyzed photosynthesis data from 2001 to 2020, finding that species richness correlates with increased photosynthesis efficiency. It warns that biodiversity loss could weaken forest photosynthesis by 3% to 17% by 2050, resulting in a carbon loss of 4.4 to 35.7 petagrams.
Facts for Prelims
- EnvironmentHigher species richness in forests correlates with increased and accelerating photosynthesis efficiency.
- FactProjected forest photosynthesis weakness due to biodiversity loss: 3% to 17% by 2050.
- FactPotential cumulative carbon loss from biodiversity decline: 4.4 to 35.7 petagrams.
- S&TTropical forests are identified as crucial carbon sinks facing deforestation and warming pressures.
