  2. Effects of climate change on the water cycle - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    The effects of climate change on the water cycle have important negative effects on the availability of freshwater resources, as well as other water reservoirs such as oceans, ice sheets, the atmosphere and soil moisture. The water cycle is essential to life on Earth and plays a large role in the global climate system and ocean circulation.

  3. Effects of climate change on oceans - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    Climate-driven changes to ocean circulation and water temperatures have affected the species' foraging and habitat use patterns, with numerous harmful consequences. [136] Warming waters lead to decreased abundance of an important prey species, the zooplankton Calanus finmarchicus. [137]

  4. Human impact on marine life - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_marine_life

    The surface salinity of the ocean is a key variable in the climate system when studying the global water cycle, ocean–atmosphere exchanges and ocean circulation, all vital components transporting heat, momentum, carbon and nutrients around the world. [84] Cold water is more dense than warm water and salty water is more dense than freshwater.

  5. Climate variability and change - Wikipedia

    en.wikipedia.org/wiki/Climate_variability_and_change

    Thermal expansion of ocean water after atmospheric warming is slow, and can take thousands of years. A combination is also possible, e.g., sudden loss of albedo in the Arctic Ocean as sea ice melts, followed by more gradual thermal expansion of the water. Climate variability can also occur due to internal processes.

  6. Ocean current - Wikipedia

    en.wikipedia.org/wiki/Ocean_current

    Ocean currents are patterns of water movement that influence climate zones and weather patterns around the world. They are primarily driven by winds and by seawater density, although many other factors influence them – including the shape and configuration of the ocean basin they flow through. The two basic types of currents – surface and ...

  7. Earth rainfall climatology - Wikipedia

    en.wikipedia.org/wiki/Earth_rainfall_climatology

    Precipitation is a major component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 486,000 cubic kilometres (117,000 cu mi) [ 2 ] of water falls as precipitation each year; 373,000 cubic kilometres (89,000 cu mi) of it over the oceans. [ 2 ]

  8. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    Over time, the water returns to the ocean, to continue the water cycle. The ocean plays a key role in the water cycle. The ocean holds "97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation". [2]

  9. Ocean - Wikipedia

    en.wikipedia.org/wiki/Ocean

    Ocean water represents the largest body of water within the global water cycle (oceans contain 97% of Earth's water). Evaporation from the ocean moves water into the atmosphere to later rain back down onto land and the ocean. [69] Oceans have a significant effect on the biosphere.
