    The main ways water vapor is added to the air are: wind convergence into areas of upward motion, [12] precipitation or virga falling from above, [24] daytime heating evaporating water from the surface of oceans, water bodies or wet land, [25] transpiration from plants, [26] cool or dry air moving over warmer water, [27] and lifting air over ...

  3. SevenMeters - Wikipedia

    en.wikipedia.org/wiki/SevenMeters

    The name SevenMeters derived from the realization that the water level will rise 7 meters if the global warming will melt all the ice in Greenland. In order to show what impact the possible climate change can have to the world, the SevenMeters group established 24 kilometers of red blinking LED-lights at 7 meters height during the UN's climate ...

  9. Sverdrup - Wikipedia

    en.wikipedia.org/wiki/Sverdrup

    In oceanography, the sverdrup (symbol: Sv) is a non-SI metric unit of volumetric flow rate, with 1 Sv equal to 1 million cubic metres per second (264,172,052 US gal/s). [1] [2] It is equivalent to the SI derived unit cubic hectometer per second (symbol: hm 3 /s or hm 3 ⋅s −1): 1 Sv is equal to 1 hm 3 /s.
