A team of researchers from the Potsdam Institute for Climate Impact Research (PIK) is now scrutinising a daring way of stabilising the ice sheet: Generating trillions of tons of additional snowfall by pumping ocean water onto the glaciers and distributing it with snow canons.


No, it isn't April 1st. This is a real story.

I love the idea. Build a first class ski-result in Antarctica, the side effect of which is that it might keep a glacier bottled up, but even better, the good will generated by the gesture allows environmental damage to happen in a place that has tried so studiously to avoid it!

Makes far more sense than, you know, slowing consumption in OECD countries, requiring single child families globally, stopping the march of fossil fuel consumption by taxing it to the moon and letting market forces work to your advantage. Nope. The world's most exclusive ski resort it is!

Where is all the heat, liberated as the water freezes, going to go?

More to the point where is all the energy to pump all that water going to come from? Solar panels?

Won't all that snow just add weight and make the ice flow quicker?

As to a sense of humour; this is a German University you're talking about!!

Salt water has a lower freezing point than fresh water which is what the glaciers are made of so it may actually melt them further. Antarctica in winter could be cold enough I suppose to melt even salt water.

The liberation of all that latent heat could even change the climate further.

Maybe cover the ice sheets with kitchen foil to reflect the heat. I should charge the European Union five euros for my in depth research project.
