Algae may degrade ecology in Antarctica

Today, a team of bioenergy experts from the University of Cambridge presented their new report on one very problematic trend – we are talking about an ever-increasing level of the so-called snow algae that appear on the Antarctic coast, thereby accumulating in traditionally snow-covered areas and diluting the relatively uniform biosphere Antarctica with new additions. Moreover, for the most part, such an addition can be quite dangerous, and not so much for the biosphere on the surface as for underwater ecosystems that are clearly not ready for such an influx of algae in the region.
The fact is that global warming is considered to be the main culprit for the active germination and spread of green algae in the Antarctic, which creates a vicious circle of entropy – with increasing temperatures, the growth rate of algae increases, which in turn allows you to absorb more carbon dioxide, which seems to be good . However, this is only one side of the coin, since in parallel with the capture and processing of large carbon dioxide, these algae also make the underwater Antarctic ecosystem warmer, darker and more difficult for various habitual inhabitants to pass through, which again closes to a local increase in temperatures.
It is worth noting the fact that such an alarming trend has been observed for several years, both with the help of ground-based monitoring equipment and with the help of the Sentinel 2 space satellite from the European Space Agency. According to current Cambridge experts, algae has already managed to cover an area of 500 acres, which is quite small in geography, but significant in terms of ecology.
Thus, the widespread presence of algae in the traditionally snowy and cold biosphere of the Antarctic leads to the fact that its microclimate changes faster, which means that glaciers are melting at an accelerated rate. It is worth noting the fact that this is why the Cambridge team decided to integrate all possible efforts in order to provide the best solution to this problem.
