In 80 years, up to 95% of the ocean surface may become uninhabitable, scientists say

    A team of scientists from the American Northwestern University found in a study that global climate change by 2100 will irreversibly change up to 95% of the world’s oceans, making them uninhabitable. They stated it in a scientific article on the Nature portal.

    The climate of the ocean surface has a characteristic temperature, acidity, and concentration of aragonite, a mineral that many marine animals use to form bones and shells. The vast majority of marine inhabitants are accustomed to these conditions.

    However, due to rising levels of CO2 in the atmosphere, the climate on the ocean surface may change.

    The authors of the study used models of the global climate of the ocean, according to which they predicted two scenarios.

    The first is that the peak in greenhouse gas emissions will occur by 2050 and continue to decline until the end of the century.

    And the second predicts that emissions will increase over the next 80 years.

    The first scenario showed that 36-95% of the surface of all oceans would completely change their living conditions. In an extreme scenario, 95% of the ocean surface will be unfit for marine life. Marine life, which exists closer to the surface, adapts to climate change by moving lower. Still, research suggests that such opportunities may be limited in the future due to almost uniform warming and oxidation of water.

    Ultimately, the researchers note, this can only be stopped if the emissions that heat the ocean stop.It is possible to fight global warming if you make an active effort now! These are the conclusions of more than 200 scientists from the Intergovernmental Panel on Climate Change (IPCC). You may read about their report here.
