Antarctic ice melt may be reversible due to rising land beneath

The melting of the West Antarctic ice sheet isn’t essentially everlasting, as bedrock cores present that a few of its ice grew again after a extra extreme thaw hundreds of years in the past. The proof means that Earth’s crust rebounding from beneath the diminishing ice, like a reminiscence foam mattress, may sluggish glacial soften and sea degree rise.

The ice sheet, which holds sufficient ice to boost oceans greater than 3 metres, sits principally beneath sea degree. …
