This is a marvelous concept that is new to me.
Envision a large number of such pipes installed in polar ice sheets. One
might focus on two goals.
The first would be to lower the temperature of the bottom of the ice sheet
in order to promote its growth from the bottom. This has the merit of
Hi Jim,
Part of the purpose of the piece is to show how such an event can have diverse
and contested interpretations; I appreciate hearing yours and Gloria's
perspectives.
I do think the idea of village science is more than just a framing or PR, and
worthy of further thought. For me village

Good news - looks like buildings, agriculture, and natural resources are going
to do the heavy lifting in solving AGW. Geoengineers need not apply. Greg

Personally, I can't see these thermal diodes being at all practical.
Far cheaper and simpler to just break up the ice, or pump water on top
of it. The maths is pretty simple. The thermal diode can only be at
a temperature of the water, at a maximum. It's heat transfer is a
function of the

The only advantage is the disposition of the salt - making ice thicker at
the bottom ensures that the salt stays in the water, not the ice. As has
been pointed out before, we don't know what happens with the salt if you
flood the ice from the top, nor whether higher-salinity ice creates a
problem
Hi
I accept that glacier grounding may have a use for thermal diodes, but
in sea ice they're pretty useless.
Breaking ice works well, because ice is an excellent thermal
insulator. Icebreaker paths are cheap. Broken, the cold air hits the
sea, and the water can also radiate to deep space.
