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.
1 Water vapor to dew-Water vapor turns from a gas into a liquid, such as dew on the morning grass. 2  Water vapor to liquid water-Water vapor fogs up glasses when moving into a warm room after being in the cold. 3  Water vapor to liquid water-Water vapor forms water droplets on the glass of a cold beverage.
