Negative Feedback From Chemical Weathering
qThe chemical weathering works as
a negative
feedback that moderates long-term climate change.
qThis negative feedback mechanism
links CO2 level in the atmosphere to the temperature and
precipitation of the atmosphere.
qA warm and moist climate
produces stronger
chemical weathering to remove CO2 out of the atmosphere č smaller greenhouse effect and
colder climate.
