It s an observation repeated loud and often by climate deniers: while Greenland melts like an ice lolly in the summer sun, Antarctica is staying chill.
According to a new scientific paper, there s no conspiracy to be found here, but rather, a manifestation of global ocean currents.
In stable periods, ocean currents help regulate our planet s climate, but when the climate is changing, this same conveyor belt can amplify differences.
In other words, the sea water encircling Antarctica hails from a time before the industrial revolution or human-caused climate change were even a thing.
The Southern Ocean is unique because it s bringing water up from several thousand meters as much as 2 miles , lead study author Kyle Armour said in a statement.
You have a lot of water coming to the surface, and that water hasn t seen the atmosphere for hundreds of years.
