Antarctica is a continent. The Arctic Ocean obviously is an ice ocean.

A landmass with ice has consistent temperatures because of the ice sitting on it, would not necessarily melt from underneath. If any melting would occur it would be the air temperatures reaching high enough to melt ice. The air circulating over Antarctica creating the "melt pools" is above freezing.

The massive Antarctica ice formations are no longer the resistance to even chronic and rapid manmade climate change.

Over the last half of the twentieth century, (click here) surface temperature over the South Pole was steady if not slightly cooling, suggesting the high Antarctic interior might be immune to warming. Research now shows a dramatic switch; in the past 30 years, the South Pole has been warming at over three times the global rate....

The South Pacific has reached temperatures high enough and the air above it warm enough that Antarctica can no longer transfer temperatures to prevent the ice over the land from melting. The ice shelves of Antarctica are over water, and in the climate crisis warm water and that is why we have over time witnessed the "Larson shelves" disintegration because of the warm waters surrounding them and underneath them.

This reporting instance is about the melting of ice over the continent of Antarctica, not the ice shelves. It is a huge difference.

...“I haven’t seen (click here) melt ponds develop this quickly in Antarctica,” said Pelto. “You see these kinds of melt events in Alaska and Greenland, but not usually in Antarctica.” He also used satellite images to detect widespread surface melting nearby on Boydell Glacier....

The South Pole (click here) has been warming at more than three times the global average over the past 30 years, a new study has found. That could have huge implications for the melting of Antarctic ice sheets, marine life in the region and the rising of global sea levels.

The study, published in the journal Nature Climate Change on Monday, sheds new light on the most remote region on Earth. While scientists have known for years that the outer regions of Antarctica is warming, they previously thought the South Pole, being located deep in its interior, was isolated from rising global temperatures...
