This could properly go in [TECH] but I'll move it one slot down the
hierachy.

There is a vast amount on web about this paper, already.
Quite apart from what "the data says", care needs to be taken to see what
the authors actually say, and what can or cannot be reasonably inferred
from their statements. A significant number of people are making statements
re what the authors have said which appear to not match what I've seen so
far.
________________

Read what they say knowing that their professional reputations, jobs and
future income depend on their being seen to be not straying too far from
received truth. This does not change what they report or even guarantee
that any given interpretation of what they say is correct - but it helps to
understand the language they are liable to adopt regardless of what they
conclude.

Significance

Thwaites Glacier is one of the West Antarctica's most prominent,
rapidly evolving, and potentially unstable contributors
to global sea level rise. Uncertainty in the amount and spatial
pattern of geothermal flux and melting beneath this glacier
is a major limitation in predicting its future behavior and sea
level contribution.

In this paper, a combination of radar sounding
and subglacial water routing is used to show that large areas
at the base of Thwaites Glacier are actively melting in response
to geothermal flux consistent with rift-associated magma migration
and volcanism. This supports the hypothesis that heterogeneous
geothermal flux and local magmatic processes could
be critical factors in determining the future behavior of the West
Antarctic Ice Sheet.
