A study highlighted in a 2022 Nature article underscores the broader climate benefits of tropical forests beyond carbon storage. Tropical forests cool the planet by one-third of a degree through biophysical mechanisms such as humidifying the air and releasing cooling chemicals, in addition to their role in extracting carbon dioxide from the air.
Forest Day is a platform for those with an interest in forests and climate change to come together with others and exchange views. Forest Day is organised by CIFOR on behalf of the Collaborative Partnership on Forests. It is held alongside the United Nations Framework Convention on Climate Change Conference of Parties (COP).
Whole ecosystem disruptions will occur earlier under more intense climate change: under the high-emissions RCP8.5 scenario, ecosystems in the tropical oceans would be the first to experience abrupt disruption before 2030, with tropical forests and polar environments following by 2050. In total, 15% of ecological assemblages would have over 20% ...
Moreover, it suggests that standing tropical forests help cool the average global temperature by more than 1 °C or 1.8 °F. [24] [25] Deforestation of tropical forests may risk triggering tipping points in the climate system and of forest ecosystem collapse which would also have effects on climate change.

A study published in Nature Climate Change in 2022 provided empirical evidence that more than three-quarters of the Amazon rainforest has experienced a decline in resilience since the early 2000s, posing risks of dieback that would impact biodiversity, carbon storage, and climate change. [74]
Land-use change can be a factor in CO 2 (carbon dioxide) atmospheric concentration, and is thus a contributor to global climate change. [14] IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere.
