That's why Antarctica's ice turned green

On 16 February 2023, one of the Copernicus Sentinel-2 satellites captured a rare image of sea ice with a green tint due to a phytoplankton bloom in the Ross Sea. In 2017, the same green ice phenomenon was observed in the same region, and according to scientists at Australia's Antarctic Climate and Ecosystems Cooperative Research Centre, the green color was caused by phytoplankton on the surface of the water, which had discolored the ice marine.

The Copernicus Sentinel-2 satellites enable monitoring of the polar regions and enable scientists to gain a better understanding of how their environment is evolving due to climate change.

Latests on Antarctica

On January 22, 2023, a new iceberg detached from the Brunt shelf in Antarctica, exceeding the size of the previous one, which had left the mainland in February 2021 heading adrift in the cold Antarctic waters.

A mountain of ice that has become the largest ever since scientists began surveying Antarctica in the 1970s. That of February 2021 was called A-74 and before the detachment of this new iceberg it was the largest block of ice ever recorded, with an area of 1,270 square kilometers.

Record that was swept away on January 22, when another huge mass of floating ice detached from the Brunt platform which is constantly monitored by scientists to also verify the path in which it is directed and if it could cause a danger to the man.

There is no concrete evidence that the large mass of ice detached from the Brunt shelf is due to the effect of climate change. However, there are other areas of West Antarctica that are losing ice due to global warming. A fact to highlight is that Antarctica lost more than 3 trillion tons of ice between 1992 and 2017.

In any case, according to what was revealed by the geologist Dominic Hodgson, this detachment would not be a direct consequence of climate change, even if there is no doubt that the earth's temperature has risen considerably, also causing global warming phenomena with consequent melting of the glaciers and raising of the sea level in general.

However, the new iceberg would have detached due to a process of natural reconfiguration of the Brunt shelf and the coast of Antarctica.
