Massive Antarctica glaciers have melted the most in at least 5,500 years
The Thwaites and Pine Island glaciers have experienced unprecedented ice loss over the past 5,500 years, according to new scientific research, suggesting the retreat could be irreversible.
The two glaciers, both part of the west Antarctic ice sheet, originated in the mid-Holocene period, roughly 7,000 to 5,000 years ago, and have remained stable until very recently. That part of Antarctica is retreating and thinning quickly, with the two glaciers melting underneath given deep, warm currents.
The melting of the glaciers could trigger extensive ice loss in that part of Antarctica, which could contribute as much as 3.4 meters to global sea level rise over the next few centuries.
