A new study from the Indian Institute of Tropical Meteorology (IITM) in Pune projects that the Western Ghats could turn into one of India's largest carbon sinks by the end of the century. Using climate models, researchers found that increased CO2 and rainfall may boost plant growth, helping the region absorb more carbon. The Western Himalayas and Northeast India are also expected to play a significant role in carbon sequestration. However, the study warns that rising temperatures and heatwaves could suppress plant productivity by increasing heat and moisture stress. Researcher Smrati Gupta noted that extreme weather events pose risks to ecosystems. The findings highlight the need for better climate models to plan for future carbon storage and ecosystem resilience in India.

Interesting projection. The Western Ghats turning into a major carbon sink by 2100 would be a big deal for India's carbon accounting. But the heat stress caveat is key. If heatwaves get worse, that extra CO2 boost might not matter much.

The study seems to rely on climate models that assume certain CO2 pathways. Would be good to see how sensitive the results are to different emission scenarios. Also, land use changes in the Western Ghats could throw off these projections.

Carbon sinks are nice but they are not a substitute for cutting emissions. The timeline to 2100 is long. We need to see near term action too. Also, how do they account for deforestation or development pressure in the Ghats?

The study mentions Western Himalayas and Northeast India as well. That is a large area. Would be interesting to see the methodology and whether they factored in land use changes or just climate variables.

If these regions become significant carbon sinks, it could affect India's NDC accounting and carbon credit potential. But the heat stress caveat is important. Policy needs to protect these ecosystems from development pressure to realize the sink potential.
