This huge volume of ice lowered global sea level by around 120 meters as compared to today.
The buttresses of ice frozen around Antarctica's edges, hundreds of meters thick in many cases, are also in the sea, but they can act like doorstops and — once moved out of the way — can allow
huge volumes of ice on the continent (in theory) to move toward the sea more easily.

So, what tourism is impacting and actually what climate change is impacting is a relatively very small piece
of that peninsula; but you know the impact on the peninsula if all that
ice melts could be
huge; when they talk about sea levels rising, you know, by inches and feet, you know if that
ice along the peninsula melts they will add to the
volume of the sea very quickly.
«This new,
huge data

of the Jackson School
of Geosciences.
The new study, accordingly, uses a computer model
of Antarctica to study the consequences
of adding

The scientists used satellite monitoring to determine the contribution
of all land - based
ice (except for Greenland and Antarctica's
huge ice sheets) to rising sea levels and found that the
volume of ice melting into the sea each year from
ice caps and glaciers was 100 cubic miles (or 417 cubic km).
