According to a study by MIT, more than half of the oceans will change color, accentuating the blue and green zones, by the mbadive death of phytoplankton
Due to climate change, the color of the oceans will change at the end of the century
By 2100, more than 50% of the oceans will have changed color due to climate change : blue and green regions will intensify, according to a study by the Mbadachusetts Institute of Technology ( MIT) [19659006] The study revealed Monday in the publication "Nature Communications" concludes that global warming is causing major changes in populations of phytoplankton, a microscopic aquatic plant, that will affect the color of the oceans.

Results predict that blue areas will be bluer, reflecting lower levels of phytoplankton – and life in general – and even greens greener, which would indicate a proliferation of phytoplankton species.
The color of the oceans depends on how the sun's rays interact with the components of the water. Water molecules absorb almost all sunlight, with the exception of the blue part, which means that the areas of the ocean where the life span is the least bright are d & # 39; an intense blue.
In addition, phytoplankton contain chlorophyll, which absorbs more blue and less than
The researchers have developed a global model simulating the growth and interaction of different species of phytoplankton and their variation in function the increase in temperatures. it has been possible to replicate the way phytoplankton absorb and reflect light and its impact on the color of the oceans, taking into account the climate change variable.
Researchers have succeeded in improving a computer model for predicting climate change. phytoplankton levels as temperatures rise.
In addition, they add a new element: the ability to calculate the light waves absorbed and reflected by the ocean. according to the quantity and types of organisms in a given region
According to this model, the appearance of the planet will be changed by the end of the century. Stephanie Dutkiewicz, the project's research director, predicts that changes between phytoplankton communities may alter food chains, which she sees as a "potentially serious" problem.
However, Dutkiewicz admits the difficulty of determining whether these changes are really
"A phenomenon like El Niño or La Niña would cause a change in chlorophyll because the amount of nutrients entering the system varies", he explains. the rights of reproduction and representation are reserved to the Agence Efe
