Climate change is triggering ocean colors: the MIT study



Scientists say that the colors of the world's oceans are activated by the end of the century as a result of climate change threatening the marine ecosystem from the bottom up.

Color of 50 percent of the ocean will change by 2100 due to changes in phytoplanktonic communities, according to a study by the Massachusetts Institute of Technology published earlier this month at Nature Communications. Scientists have said that blue water in the subtropical regions will be more bluish, whereas now green water near the poles will become more green.

Phytoplankton, or algae, which scientists say, are ] which may vary depending on the temperature of the ocean, which, as several climatic studies have shown, is growing rapidly. The study used a climatic model that projects changes to the ocean throughout the century and showed changes in the color of the ocean in the world, which is 3 degrees warmer ̵

In phytoplankton there is a green pigment called chlorophyll, so the surface of the ocean with higher populations of phytoplankton looks greener, and surfaces with less phytoplankton are more bluish

. which leads to a change in the color of water. Warming in subtropical areas can save phytoplankton nutrients and reduce their population, but warming in the polar regions can provide a better environment for their growth. Scientists have said that color changes will be too gradual for the average individual over time, but this shift is a much greater indicator of other ocean problems.

"This can be potentially quite serious," says author Stephanie Dutkevich 19659003] in a press release . "If climate change changes one phytoplankton community to another, it will also change the types of food networks they can support."

Phytoplankton is the basis of the food chain of marine life, so a reduction in algae may trigger a reaction that affects the population of ocean fish. Algae also absorb atmospheric carbon dioxide for photosynthesis, so reducing phytoplankton can mean more carbon dioxide in the air

.

"Changes are due to climate change," Dutkevich said The Washington Post . – There will be a time until we statistically show it. But changing the color of the ocean will be one of the earliest warning signals that we have actually changed our planet. "
