Arctic ice turning green due to global warming: scientists warn

Ice in the Arctic region is increasingly turning green due to unprecedented massive blooms of phytoplankton and scientists have once again blamed global warming for the issue.

Normally, phytoplankton shouldn’t be able to grow under the ice as ice reflects most of sunlight that falls on it back into space. In other words, ice blocks sunlight from reaching the water beneath, and phytoplankton can’t growth in absence of sunlight.

However, Arctic sea ice has gotten thinner over the past few decades due to increasing temperatures, allowing more sunlight to enter the water below, and helping massive blooms of phytoplankton to grow.

Chris Horvat, an expert from the Harvard John A. Paulson School of Engineering & Applied Sciences, said, “Our big question was, how much sunlight gets transmitted through the sea ice, both as a function of thickness, which has been decreasing, and the melt pond percentage, which has been increasing.”

The researchers eventually found that the Arctic region went from a state where there was not any potential for massive blooms of plankton to being susceptible to such types of growth.

The researchers also warned that massive blooms of plankton could become more frequent in the future, causing significant disruptions in the marine food chain.
