Deforestation-driven climate–carbon cycle feedback
parameter.
✓ Climate warming is projected in
CMIP5 and CMIP6 models to
reduce tropical land carbon storage,
which is described by a γ
parameter that is often negative in
sign for tropical terrestrial
ecosystem.
✓ In relation with the response of
land carbon storage to climate
change, the researchers found out
that the most negative γCO2 AGB
is in the Amazon, with smaller
magnitude of γCO2 AGB values in
the Congo and across the islands
in
tropical Asia. (Same goes with the
deforestation-driven climate–
carbon feedback
parameter)
Amazon Rainforest Die-off due to Climate
Change brought about by Deforestation
• The biophysical effects of
deforestation influence the
aboveground vegetation of carbon
mainly through a regionally
concentrated rainfall response,
with the temperature response
being much smaller.
• The study, in general, deems to
suggest that the positive carbon–
climate feedback from
deforestation is fundamentally
larger than the feedback
originating from fossil emissions.
