Who says there can't be crime and intrigue in the world of paleontology? Here's a really interesting report of a possible black market sale of fossilized dinosaur bones, blown open by a museum paleontologist. Why do I want to think Scooby Doo and Shaggy will help solve this situation?

Wait, JGordon!! Before we go any further, I have something to ask you.

Yes, JGordon?

How is ice our ancient friend?

Because it soothes our hot tempers, and it makes strong drinks more palatable.

And hotness? Why is it our enemy?

Because it makes us uncomfortable when we have it, and it makes us feel unattractive when we don’t.

I see. But don’t you think that was a long title for a blog post?

Maybe. Don’t you think that anyone whose time is at all valuable will have stopped reading by now because of this needless discussion?


OMG! What were we even talking about? I’m a little out of sorts because I was up all night killing the rats in my apartment. You think that’s weird? How about this: this morning, there were no dead rats to be found! It could be that they were only playing dead, or it could be that, like Obi-wan Kenobi, striking them down only caused them to become more powerful than I could possibly imagine, and also to vanish.

Or it could be that too much heat and not enough cooling ice in the apartment caused me to hallucinate the whole episode. However could that be remedied?

Well, the country of Mongolia has an idea. Or, more specifically, it’s capital city, Ulan Bator, and a local engineering firm have an idea: create mini-glaciers to place around the city. The idea behind the mini glaciers isn’t so much to prevent rat hallucinations (although that’s definitely a bonus) as it is to combat the effects of global warming and the city’s urban heat island (cities, with all their paved surfaces and heat-absorbing materials, tend to heat up more than the surrounding countryside). This could reduce the need for energy-hungry air conditioning in the city. The melting ice could potentially also be used to supplement the area’s drinking water and irrigation needs.

But how are the sons and daughters of the Great Khan going to pull this off? You can’t just hallucinate a gigantic block of ice into being. I should know.

The plan is to make a sort of mini-glacier naturally in the winter, using river ice. Typically, ice on a body of water won’t form more than a few feet thick, because at that point the ice itself insulates the water below from the cold above. But in situations where the water can be forced up through cracks or holes in the ice, it will form more ice on top, adding layers until the ice is many meters thick. These giant sheets of ice, called “naleds” or “aufeis” can last well into the following summer, as they slowly melt away.

The Mongolian engineers are planning on helping naled formation along by regularly drilling holes in river ice, so water can flow more freely up to be frozen. The block or blocks of ice produced will then be transported to the city, where they will … be cool, I guess.

The project will begin this winter, and if it’s successful, it could be a model for small-scale geoengineering (if that’s not an oxymoron) in northern cities as global climate warms. While glaciers and permafrost area will likely shrink, annual naled formation will continue. The project engineers think that naleds could also be used to actually repair areas of damaged (thawing) permafrost.

The articles on the project don’t get very specific on the size or placement of the naleds, but I suppose it’s also possible that, if they cover enough area, they would increase the city’s albedo—objects with high albedo reflect more light and absorb less of it, which means that they will heat up less in sunlight.

I’m afraid that my hot apartment hallucinations will force this project out of my memory by tomorrow, but it would have been interesting to see what sort of results come from it, and whether other countries pick the idea up as a cost effective method for dealing with rising summer temperatures. But I’ll leave that up to you, Buzzketeers. And to you, JGordon, my hot friend.

The Royal Tyrrell Museum in Alberta, Canada led a fossil-hunting expedition to Mongolia. The trip just recently ended, but you can read all about it on their blog.
