Abstract:
Large-scale tree planting is advocated to provide additional atmospheric
cooling and further reduce global warming. This raises a question about the
present time. Do trees cool or warm the atmosphere? This question does not have
a simple yes or no answer. Examination of the greenhouse effect, global warming
and the carbon cycle and how trees and forests function provides the basis for
understanding how forests might cool or warm the atmosphere. Results from
research and models indicate that cooling or warming depends on where forests
are located and the type and colour of trees. Cooling generally prevails over
warming, but this may change. Trees and
Global Warming will appeal to anyone interested in climate change, ecology
and conservation.
