YRF Overcrowded trees are under competitive stress from their neighbors. Thinning may be done to increase the resistance of the stand to environmental stress such as drought, insect infestation or extreme temperature.
Rising global temperatures are expected to cause greater evaporation of water vapor into the atmosphere, primarily from the oceans. On one hand, we know that water vapor is a powerful greenhouse gas, so an increase in water vapor might be expected to produce yet more warming through an enhanced greenhouse effect.lobal warming accelerates evaporation, placing more water vapor in the air. More water vapor generates a a stronger greenhouse effect, since water vapor is a greenhouse gas. However, it may also lead to the formation of more clouds, which might help cool the planet by increasing Earth's albedo.
Water vapor is water in its gaseous state-instead of liquid or solid (ice). Water vapor is totally invisible. If you see a cloud, fog, or mist, these are all liquid water, not water vapor.Water vapor is extremely important to the weather and climate. Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form.f you see a cloud, fog, or mist, these are all liquid water, not water vapor.
