The snow in Antartica is turning green.

And that’s not cool.

At least not according to a recent CNN report because it says that green snow is caused by blooming algae. And that blooming algae is caused by rising temperatures and is likely to spread as climate change continues. It said scientists have used satellite data gathered between 2017-2019 as well as on-the-ground measurements to map the spread of the bloom.

The report says the algae needs high temperature and wet snow to grow, and it said “unusually high temperatures” were recorded in Antarctica in February and the continent had a “nine-day heatwave” earlier this year.

How much green snow is out there?

Well, the report said scientists identified 1,679 separate blooms which is about two, square kilometers of the stuff. Bird populations – their poop acts as fertilizer for the algae — could have an impact on the blooms as well.

And, the report said, an increase in the blooms could lead to an increase in snow melt.
