The problem with that theory is...actual science: The Antarctic land ice, because of its weight, sits in a bowl. Ice doesn’t flow uphill.
Their theory also depends on the ice never getting replenished on the continent. Just like how rain and snow fall on mountains, only to collect into rivers which flow down hill to the oceans, ice does the same thing in glaciers. All ice that breaks off Antarctica is replaced by new snow on the continent.
“All ice that breaks off Antarctica is replaced by new snow on the continent.”
Yup:
Interior gains exceed losses (on the coasts). (Zwally2015)
Which means (net) Antarctic ice is not melting but gaining, which means it’s a net loss for sea-levels, which means all sea-level papers and measurements on the subject prior to Zwally are completely WRONG.
