Density Matters

Great Lakes flooding hazard because of excess ice and snow

original

This is related to why frozen soda cans expand and sometimes burst and also why ice floats.

Plus 80 calories per gram of ice to melt ice just so it can slither back to a liquid state is a lot of heat to suck up.

If I were a farmer, I would delay spring planting.

Great Lakes Ice Cover is 91.8%

That's pretty rare. I think they've never in recorded history been entirely frozen over, and the record is around 95%. Lake Michigan ice is also verging on a record, Superior is pretty well frozen over.

Id like to skate from Duluth to Buffalo!

Great pics, Lem. Makes me almost want to drive up and see it :)

Cool pictures of Niagara, although it appears they mean "mostly frozen over."

Meanwhile up in my part of Northern California we are having a really warm winter and instead of our normal freezing temperatures, we are having rain, thundershowers today. Did I mention.....lots of rain Trickle trickle

Drought isn't over yet, but damn it is WET.

We really need the snow pack. Can Michigan send us some ice?

The linked article lays the blame for decreased water levels on "warming climate", of course, with the most severe decreases occurring in Lakes Michigan and Huron. What few people know is that our own Corps of Engineers is mostly to blame for the inability of water levels to recover in those lakes thanks to over dredging in Lake St. Clair.

That was a very interesting article Third Coast.

Patrick said...

I looked for an update to Third Coast's story, which was from 2012. I came up with

This, from today, which links that story.

I notice that the dredging in the St. Clair river doesn't bear mention until the end of the story.

Just saw a picture of a white Nissan Cube - license plate C6H12O6 - that's for you, CL.

You see it on Brandywine Creek all the time.

The symmetry of that compound is fascinatin'.

chickelit said...

Glucose? It looks symmetrical but it's really not. It belongs to the point group C1 which is the least symmetric group of molecules.

One of your bowls probably belongs to the point group C∞V.

"C∞V"reads "C-infinity-V"
