ANTARCTIC APOCALYPSE ON THE MAKING?
”Enten, tenten, telika menten, olle, dulle, doff, kinke lade koff”…
Enten, tenten, telika menten, pirum parum puff!
It almost comes like from the Hogwarth School of Wizardry that the 2012
visionaries predict the Antarctic ice demise in some magic
'...at some point within the next few decades...': Kelly, we have had
a scant 2 decades of major concern and political activism re climate
change; in that time things have moved rather more rapidly than anyone
anticipated and show no signs of slowing down. The concern that many
of us have is that
Jim-- I think this is the key takeaway from Kelly's note, which seems
patently obvious to me.
Such research is the pre-cursor to any effort to geoengineer anyway,
so it is both a solid argument and a reasonable way to advance to the
next relevant set of activities without damaging credibility or
Just for laughs...
This is wonderful eye candy.

Of course the question is how much cooling would they provide. It
would be permanent of course. (Ah well...)
Great to see the 3D renderings from the POV of different cities and
When I was a post-doc at Penn State working with Jim Kasting we did
calculations of changes in solar flux from rings as a possible explanation
of low-latitude glaciations in the ancient past, but we didn't published
them. I think we decided you would need quite a ring to freeze the equator.
At
Bad ideas abound Dan. This is one of them. Permanent rings around the
earth will screw things up in a lot of undesirable ways we might
regret later. How would you do that? Take huge ice chips off castillo
and ship them to earth orbit?

As a firm believer in scientific research and improvement of the human
condition through scientific advances I agree with your opinion that
research should be presented without 'benefit' of political
correctness. You note that, We as scientists have a responsibility
to publish our best work and
If the soviets built an orbital ring it would be made of cast iron and
heavy enough to resist light pressure.
