    A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...

  3. Critical Atlantic Ocean current system is showing early signs ...

    A crucial system of ocean currents may already be on course to collapse with devastating implications for sea level rise global weather — leading temperatures to plunge dramatically in some ...

  4. Ocean current - Wikipedia

    en.wikipedia.org/wiki/Ocean_current

    Knowledge of surface ocean currents is essential in reducing costs of shipping, since traveling with them reduces fuel costs. In the wind powered sailing-ship era, knowledge of wind patterns and ocean currents was even more essential. Using ocean currents to help their ships into harbor and using currents such as the gulf stream to get back ...

  5. Tipping points in the climate system - Wikipedia

    en.wikipedia.org/wiki/Tipping_points_in_the...

    The 2019 IPCC Special Report on the Ocean and Cryosphere in a Changing Climate defines a tipping point as: "A level of change in system properties beyond which a system reorganises, often in a non-linear manner, and does not return to the initial state even if the drivers of the change are abated. For the climate system, the term refers to a ...

  6. A major Atlantic Ocean current could collapse as early as 2025

    Researchers warn that a collapse of the AMOC could be far-reaching, impacting tens of millions of people. Skip to main content. 24/7 Help. For premium support please call: 800-290-4726 more ...

  7. Marine current power - Wikipedia

    en.wikipedia.org/wiki/Marine_current_power

    Marine currents can carry large amounts of water, largely driven by the tides, which are a consequence of the gravitational effects of the planetary motion of the Earth, the Moon and the Sun. Augmented flow velocities can be found where the underwater topography in straits between islands and the mainland or in shallows around headlands plays a major role in enhancing the flow velocities ...

  8. Effects of climate change on oceans - Wikipedia

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

    Any changes in ocean currents affect the ocean's ability to absorb carbon dioxide (which is affected by water temperature) as well as ocean productivity because the currents transport nutrients (see Impacts on phytoplankton and net primary production). Because the AMOC deep ocean circulation is slow (it takes hundreds to thousands of years to ...

  9. A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid-century, according to a new study, and scientists have said before that such a collapse ...
