‘Extraordinary thinning’ of ice sheets revealed deep inside Antarctica

The Guardian Thinning Ice Sheets 5/16/2019

The warming of the Southern Ocean is resulting in glaciers sliding into the sea increasingly rapidly, with ice now being lost five times faster than in the 1990s. The West Antarctic ice sheet was stable in 1992 but up to a quarter of its expanse is now thinning. More than 100 metres of ice thickness has been lost in the worst-hit places.

‘Archived’ heat has reached deep into the Arctic interior, researchers say

Yale News-Archived Heat in the Arctic

Arctic sea ice isn’t just threatened by the melting of ice around its edges, a new study has found: Warmer water that originated hundreds of miles away has penetrated deep into the interior of the Arctic.
That “archived” heat, currently trapped below the surface, has the potential to melt the region’s entire sea-ice pack if it reaches the surface, researchers say.

Scientists are keeping a close eye on the Beaufort Gyre

PRI- Beaufort Gyre

The Beaufort Gyre, an immense 60-mile-diameter pool of cold freshwater and sea ice, is “stuck” in a clockwise rotation that should have ended years ago. Its eventual reversal could send massive amounts of chilly water straight toward western Europe, plunging it into brutal winters and disrupting fisheries.

Warming of the interior Arctic Ocean linked to sea ice losses at the basin margins

Science Advances- Warming of the interior Arctic Ocean linked to sea ice losses at the basin margins

Arctic Ocean measurements reveal a near doubling of ocean heat content relative to the freezing temperature in the Beaufort Gyre halocline over the past three decades (1987–2017). This warming is linked to anomalous solar heating of surface waters in the northern Chukchi Sea, a main entryway for halocline waters to join the interior Beaufort Gyre.

'We've never seen this': Massive Canadian Glaciers Shrinking Rapidly

The Guardian- Glacier Shrinkage-10/30/2018

Scientists in Canada have warned that massive glaciers in the Yukon territory are shrinking even faster than would be expected from a warming climate – and bringing dramatic changes to the region.
