When Being Green Isn't Good

There have been masses of changes (notably with record high temperatures) to Antarctica since the above old map was published.  The latest is a greening of substantial areas of ice by single celled algae, that are forming new 'ecosystems' with fungi and bacteria in the slush (https://www.theguardian.com/world/2020/may/20/climate-change-turning-parts-antarctica-green-say-scientists-algae).  Although the algae photosynthesise, removing carbon dioxide from the atmosphere, they are likely to further exacerbate global warming by reducing the reflectiveness of the ice (this normally reflects solar energy back into space).
