You can’t make up stupid like this. First they claim that global warming is causing glaciers to retreat away from the sea. Now they claim that global warming is causing glaciers to advance towards the sea.
Until they noticed that their theory wasn’t working a few weeks ago, they were screaming that all of the ice would be gone this year because of global warming. Now they say the exact opposite.
Sea ice forms at the periphery of the ice pack as cold air freezes seawater. The contribution of glacial ice is tiny, and occurs near land. Record Antarctic sea ice (by definition) forms far away from land.
