Lots of land up here.
Lots of water down here.
Between latitude 40S and 60S, there is 23% of all the global ocean surface area and 1.6% of all the global land surface area. Since the oceans have much greater thermal mass that land, nearly a quarter of the thermal mass of the globe is confined to this 20 degree band of latitude. This happens to be the home of the Antarctic Circumpolar Current.
A five degree latitude change in the ACC path caused by atmospheric circulation patterns and/or change in the sea ice extent would impact global climate significantly. No need to think albedo forcing, just simple thermodynamics. This area is the window to the thermally isolated continent of Antarctica with an average annual temperature of around -30 C degrees, where an area the size of the continent of Australia changes from open water to sea ice every year.
This table makes a nice reference. More than twice the surface area of the Earth is between 45N and 45S, the land of sunshine. Nearly half of the surface is between latitude 25N and 25S in the tropical zone and only 53.3 million kilometers squared of 214.7 million kilometers squared total is land surface in the tropical zone. Between ~45N and 90N, there are 30.8 million kilometers squared of ocean, ~8.5% of the 361 million kilometers squared of total ocean surface area and 37% of the ocean surface area between 40S and 60S.
