India, May 27 -- Scientists warn these signs are an early warning indicator that these areas are approaching a threshold to a die-off event

More than a third of the mature Amazon rainforest - 37 per cent - is struggling to recover due to frequent droughts over the past two decades.

A new study has highlighted that the world's largest tropical forest, which is a biodiversity hotspot with over 15,000 tree species and serves as the largest carbon sink, is showing signs of 'critical slowing down' of vegetation activity.

The paper warned these signs are an early indicator of dynamic systems approaching a critical threshold, beyond which the forest would function differently. It further suggested that climate change may be the potential driv...
