When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.

    The IPCC AR5 concludes that tropospheric water vapor has increased by 3.5% over the last 40 years, which is consistent with the observed temperature increase of 0.5 °C. [12] The human influence on the water cycle can be observed by analyzing the ocean's surface salinity and the "precipitation minus evaporation (P–E)" patterns over the ocean.

A mere 2.5 percent of all primary care doctors have gone through the certification process. “I cannot say it enough,” said then-Sen. Carl Levin (D-Mich.) at the meeting.

  9. Deep water cycle - Wikipedia

    en.wikipedia.org/wiki/Deep_water_cycle

    Estimates of the amount of water in the mantle range from 1 ⁄ 4 to 4 times the water in the ocean. [12] There are 1.37×10 18 m 3 of water in the seas, therefore, this would suggest that there is between 3.4×10 17 and 5.5×10 18 m 3 of water in the mantle. Constraints on water in the mantle come from mantle mineralogy, samples of rock from ...
