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.
The water vapor in your breath is warmer than the outside air. The water vapor molecules transfer energy to the colder air. This makes the water vapor molecules move more slowly. Their attractions overcome their motion and they join together or condense to form liquid water. Evaporation and condensation in the water cycle One common place you see the results of evaporation and condensation is in the weather.
