The response of the Antarctic Circumpolar Current to recent climate change*

Around and around the southern pole
The Antarctic Circumpolar Current, inspiring
Around and around the southern pole
Seemingly without a goal
Going east, east, east, untiring
East, east, east, admiring!
Around and around the southern pole

Around and around the southern pole
To “the mightiest of all ocean currents” people bowed
Around and around the southern pole
In the Southern Ocean playing the most important role
Despite going slowly, it has never slowed
Enormous amounts of water have flowed
Around and around the southern pole

Around and around the southern pole
Up to 2 kilometres wide
Around and around the southern pole
2 to 4 km deep the flow, no shoal
putting Atlantic, Indic, Pacific, side by side,
connecting them with an enormous tide
Around and around the southern pole

Around and around the southern pole
No continents are in it’s way, by winds the whole is driven
Around and around the southern pole
Blending the world’s oceans’ waters in its endless stroll
Oceans that otherwise are riven
Its importance for climate is given
Around and around the southern pole

Around and around the southern pole
As climate changes, so does the driving wind field
Around and around the southern pole
But studies show that on the whole
Despite the ocean being exposed to winds without shield
In total no changes to the current are yield’d
Around and around the southern pole
