Antarctica snow is turning green, climate change to fuel blooming algae growth: Study
Snow is turning green in the Antarctic Peninsula due to the blooming algae which are likely to spread as temperatures increases as a result of climate change

sw is turning green in Antarctic Peninsula due to blooming algae which are likely to spre as temperatures increases as a result of climate change. According to researchers, green sw algae multiplies in warm temperatures and gets habitable in regions of wet sw.
green sw algae are microscopic organisms when measured individually but when organisms grow simultaneously, y turn sw bright green and can even be spotted from , researchers said in a study published in Nature Communications journal on Wednesday, May 20.

researchers have also created first large-scale map of organisms and ir movements by garing satellite data of over two summers in Antarctica between 2017 and 2019, which allowed scientists to map microscopic algae as y bloomed across sw of Antarctic Peninsula.

warmer areas in Antarctic coastline are usually seen with patches of green sw algae. aver temperature in coastline is little above zero degrees celsius during Sourn Hemisphere's summer months of vember to February, study ded.
researchers furr highlighted that Antarctic Peninsula is part of region that has experienced most rapid warming in latter part of last century. High temperatures were recorded in February and a nine-day heatwave burnt continent's rrn tip earlier this year.

Organism to expand as global temperatures increase
Researchers believe organisms will expand as global temperatures increase. Scientists classified 1,679 separate blooms of green algae on sw surface, covering an area of 1.9 km2 -- which equates to a carbon sink of around 479 tons per year. A carbon sink is a reservoir that absorbs more carbon than it releases.

Spre of algae linked to birds
As per study, spre of organisms is linked to bird populations whose excrement acts as a fertilizer to expedite ir growth. As Penguin populations are affected by warming temperatures, sw algae could lose sources of nutrients to grow, researchers said.
