The snow in Antarctica is turning green.
And it’s not cool.
At least not according to a recent CNN report because it says that green snow is caused by flowering algae. And flowering algae is caused by rising temperatures and is likely to spread as climate change continues. It said scientists used satellite data gathered between 2017-2019 as well as ground measurements to map the spread of blossom.
The report said that algae needed high temperatures and wet snow to grow, adding that “unusually high temperatures”; were recorded in Antarctica in February and that the continent had a “nine-day heatwave” earlier this year.
How much green snow is there?
So, the report says scientists have identified 1,679 separate blooms of nearly two, square feet of stuff. Bird populations – their poop acts as fertilizer for algae – can have an effect on blooms as well.
And, the report said, an increase in blossoms could lead to an increase in melting snow.
