Up to 66 per cent of key biodiversity areas (KBAs) in tropical forests have recently entered a Mean annual temperature regime.
KBAs are sites contributing significantly to the global persistence of biodiversity in terrestrial, freshwater and marine ecosystems.
The proportion of KBAs with new temperature regimes was 72 per cent in Africa, 59 per cent in Latin America and 49 per cent in Asia and Oceania.
The 2.9 per cent of KBAs in Latin America and 4.9 per cent in Asia and Oceania have recently transitioned to almost entirely novel temperature regimes.
Only 0.02 per cent of KBAs in Asia and Oceania remained almost stable.
34 per cent of tropical forest KBAs are not yet experiencing the new temperature regimes.
