98%

Explanationabout:

about 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft).

Explanation:

Partnership: in this poem we are presented with a couple who seem to have had an argument. ... Conflict: at the start of the poem there is a sense that the couple have been arguing, or had a difficult situation to deal with. 'we skirted the lake, silent and apart' 'Skirted' suggests avoidance.
