The argument is that the increased separation of the Antarctic
land mass from South America led to the creation of the powerful Antarctic Circumpolar Current which acted
as a kind of water barrier and effectively blocked the warmer, less salty waters from the North Atlantic and Central Pacific from moving southwards towards the Antarctic
land mass leading to the isolation of the Antarctic
land mass and lowered
temperatures which allowed the ice sheets to form.
While historical

as the

Whilst it's natural to start with air
temperatures, a more thorough examination should be
as inclusive
as possible; snow cover, ice melt, air
temperatures over
land and sea, even the sea
temperatures themselves.
However, for the globe
as a whole, surface air
temperatures over

as well.
The former is likely to overestimate the true global surface air
temperature trend (since the oceans do not warm
as fast
as the
land), while the latter may underestimate the true trend, since the air
temperature over the ocean is predicted to rise at a slightly higher rate than the ocean
temperature.
Temperature changes relative to the corresponding average for 1901 - 1950 (°C) from decade to decade from 1906 to 2005 over the Earth's continents,

as noted above.
As stated in the paper, that could reflect an error in the
land temperature reconstruction (too cold), an error in the ocean reconstruction (not cold enough) or an error in the models

Meanwhile,
as oceans heat up, thermal expansion causes sea levels that are already rising from the melting of
land ice (triggered by higher air and sea
temperatures) to rise even more.
