Thwaites Glacier Startles Scientists | Dissident Voice

“It’s a disturbing discovery,” according to Pietro Milillo, a radar scientist at NASA’s Jet Propulsion Lab, who co-authored a recently published study: “Heterogeneous Retreat and Ice Melt of Thwaites Glacier, West Antarctica”, Science Advances, Vol. 5, No. 1, January 30, 2019.

It’s only within the past 10 years that NASA’s IceBridge Mission has served as the largest airborne survey of Earth’s polar ice, providing unprecedented three-dimensional views of Antarctica’s ice sheets, ice shelves and sea ice. Scientists are now able to peer into glaciers with remarkable accuracy to see what’s happening.

Indeed, scientists are getting an eyeful, and they are discovering the true impact of global warming, which is much more powerful and happening considerably faster than they ever dreamed possible.

After all, the ocean has been absorbing most of the planet’s heat, and that heat finds its way underneath in the water, thus creating gigantic melt holes, like the recently discovered Thwaites Big Cavity. As such, considerable damage is/has been hidden from view.

The new NASA study, utilizing IceBridge, shows a surprising loss of 14B tons of ice in only three years from the Thwaites Glacier, where a humongous hole lurks beneath the glacier’s icy/snowy surface, a massive cavity nearly the size of NYC but hidden within the core of the ice sheet.

Fascinatingly, it’s calculated that Thwaites is responsible for anywhere from 5% to 10% of worldwide annual…
