Plankton may not survive global warming with "devastating effects" - Oceanographic

Scientists warn of the "devastating impact" upon marine ecosystems and food supplies if plankton can't survive current temperature rises.

    Within 70 years?

    I’m not saying you are wrong or this isn’t useful data, but we would have to get extremely lucky not to feel devastating impacts before 70 more years go by.

    Model based, but hard to understand why:

    1. Ocean temperatures have risen significantly just in last 2 and 8 years. (Tropical Atlantic ocean is already consistent with what 2C of warming would bring)
    2. Even with 2 or 4C or higher warming, there will be ocean that is less than 31C surface temperature.

    Why can’t plankton move to cooler waters?

      It will move to cooler water, that is explicitly mentioned in the paper this article is based on. But the reduction of habitat area as a result of that will significantly reduce the total plankton biomass.

        Thank you. Makes sense that more plankton can grow (capture CO2 as well) if more of the ocean is cool enough. Headline implies worse than lower plankton population.
