Scientists Propose Plan To Re-Freeze the Arctic (inhabitat.com)

Kristine Lofgren writes: In case you've been under a rock for the past 20 years, the Arctic is melting super fast. Certain *ahem* governments are dragging their feet doing anything about it, which means the planet could be in for a spectacular meltdown within the next 20 years. But a clever bunch of scientists have hatched a plan to re-freeze the Arctic using wind-powered pumps that will bring water to the surface, allowing it to freeze. This new layer of ice could last well into the summer, which is vital, because scientists think summer Arctic ice could be gone by 2030 -- and that causes a whole chain of terrible events that will only make our climate change problem much, much worse. The plan has a $500 billion price tag, but that's pocket change compared to the cost of dealing with an ice-free Arctic. The study has been published in The American Geophysical Union's journal Earth's Future. You can read more about the study via The Guardian.

    Here's how arctic sea ice has fared relative to IPCC projections: http://neven1.typepad.com/.a/6...

  3. The plan is to pull water to the surface. by robbak · · Score: 4, Informative

    Normally, the sea ice freezes over the water, capping it off and insulating it. Heat soaks only slowly through the ice, cooling the water under the ice and freezing it, slowly.

    Instead, if we pump seawater up and drop it on the top of the ice, it will freeze quickly. So we can increase the thickness of the ice, so it will, hopefully, last longer.

    If done on a large scale, however, it will warm the arctic winter, as heat is added to the system in the form of liquid water to be frozen, water surface that is 0 degrees C instead of solid ice at maybe -20 degrees C. The increased ice is probably a net positive for the artctic, but I dislike all these goengineering kludges.

    ...we really ought to be getting our asses in gear and looking at the impact of mitigation strategies at the 'global environmental engineering' scale, and maybe doing a few local-scale tests to help build better models to aid in the assessments.

    The idiocy in this is not only in engaging in dubious and expensive schemes that will either not work, may exacerbates the instability of the climate, could be irreversible, might lead to run-away effects etc etc - but we are doing this to avoid having to simply make a few, easy adjustments to our lifestyles, like cut back on brainless consumerism and the myth that the economy must - or even can - grow forever. We are already living on borrowed time; we are using up limited resources and we still resist even thinking about renewable energy - we are only able to feed the 7+ billion people on the planet by spending lots of energy on producing artificial fetilizers (something like 40% of the nitrogen in our bodies now comes from artificial fertilizer - check for yourself). We are already at the point where it would take just 1 year or so of disruption in our chemical industries to produce a worldwide hunger catastrophe, just to put it into a bit of perspective.

    All in all, we really do need to be willing to accept changes - wasting effort on hare-brained shemes is stupid. Climate is only one of the big threats we face, and we can to some extent simply adjust to it, but unless we learn to curb overconsumption in a serious way, it won't matter all that much. Call me alarmist if you will, but I'd much rather be ridiculed by morons today, than have my children and grand-children live through the alternatives.

    It's a fraud because he doesn't like the conclusions. End of.
