Forests have a lower albedo than open land so
deforestation increases albedo (but for the record, no, chopping down all our forests is not the solution to global warming).
Forests provide a low albedo (and
deforestation increases albedo).
Deforestation increases albedo.
Not exact matches
The rise of CO2 from 270ppm to now over 400ppm, the extent of equatorial and sub tropical
deforestation, the soot deposits on the polar ice caps, the
increase in atmospheric water vapour due to a corresponding
increase in ocean temps and changes in ocean currents, the extreme ice
albedo currently happening in the arctic etc, etc are all conspiring in tandem to alter the climate as we know it.
Forcing from surface
albedo changes due to land use change is expected to be negative globally (Sections 2.5.3, 7.3.3 and 9.3.3.3) although tropical
deforestation could
increase evaporation and warm the climate (Section 2.5.5), counteracting cooling from
albedo change.
Land cover changes, largely due to net
deforestation, have
increased the surface
albedo giving an RF of — 0.2 [± 0.2] W m — 2, with a medium - low level of scientific understanding.
Furthermore,
deforestation in the middle — high latitudes might have amplified Little Ice Age cooling by exposing more snow and
increasing surface
albedo (107, 110, 111).
Stopping tropical
deforestation and
increasing tree planting in REDD + countries, where the
albedo effect is smaller than the carbon effect, makes sense from an energy balance point of view.
