"There is enough ice in Greenland to raise the sea levels by 7.5 meters, that's about 25 feet, an enormous volume of ice, and that would be devastating to coastlines all around the planet," said Willis. "We should be retreating already from the coastline if we are looking at many meters [lost] in the next century or two."

Quote:
Helheim has become famous in recent years as it has been retreating at a stunning rate. In 2017, the glacier lost a whopping two miles, and a year later scientists from New York University captured a miles-long ice column break off the glacier's front. The melt doesn't seem to be slowing this year either.
"It retreats by many meters per day, it's tens of meters per day. You can probably set your iPhone on timelapse and actually see it go by," Willis says as the data flashes up on his phone screen.

That is a dark, gruesome book.

To desert dwellers, an idea that makes intuitive sense is to pipe Lake Superior water to where it’s “needed.” Such a project would be staggeringly expensive but technically doable; besides, the Great Lakes surely wouldn’t miss, say, 50 billion gallons — would they?


I know it sounds like a lot, but people don't realize how little 50 billion gallons really is.

Let's do some fun math:

My household uses between 3,000-3,500 gallons a month. (We don't irrigate at all, so we're below the average. But if we're talking about piping water that far, you better believe irrigation is going to be banned for residential purposes.)

We'll go with the high amount of 3,500/month. That's 42,000 gpy. 50 billion gallons will provide that annual amount of water to 1.19 million homes. That's it. And remember, 3,500/month is below the average.

So even if they would take that amount, the need wouldn't be met. Yes, it would only be 1.6% of Lake Superior, but the need still wouldn't be met.

Conservation & efficiency is still the best first step. Reuse is the next best step.

I think they also over-estimate how "staggeringly expensive" such a project would be. DAPL cost ~$4 billion, and has a capacity of about 25 million gallons per day. About 9 billion gallons per year, give or take some operational disruptions.

You add a bit of length, run 2 lines at slightly larger diameters with bigger pumps, subtract some engineering precautions because you are transporting water vs. crude oil, and you can get to that 50 billion gallons pretty easily for likely less than $15 billion. Sure, not cheap, but pretty small pennies for such a large federal project.

Also by my math, Lake Superior is ~3,196,543 billion gallons. So you could drain 50 billion gallons a year for 100 years, and still only drain 0.15% of the lake.

Nowhere near the the water of Superior, but the Colorado River doesn't reach the Sea of Cortez anymore.
The Salton Sea thing.

All water resources are limited, obviously.

A guy from StL paddled the Missouri River this year. His blog mentioned some odd stuff along the river. This being one of them. (he plans to research it more, I'll be interested in that)
He was told by a farmer he met up there - they use this largely to irrigate fields for corn and sugar beets. Upper plains get typically get about half the rain they need to grow sugar beets.
If you own land along the river, you can just pump out water for irrigation apparently.

Can't pipe water out of the Great Lakes to the desert southwest or wherever else. All the states bordering the lakes have a legal treaty barring sale or transportation of water to a non-great lake state. To access lake waters you must be located within the drainage basin of said lakes.

https://en.wikipedia.org/wiki/Great_Lakes_Compact

Passed by US Congress and signed into law by GW Bush in 2008. Sorry my desert-dwelling peeps. Maybe you can pipe it in from the Gulf of Mexico.

Yes but that was only enough water for a little over 1 million homes. There are like 11 million homes just in California.

You know damn well California farmers will want to use this water. Farming is a much, much bigger user of water than homes. Farming accounts for about 70% of all water use globally. California has an agriculture industry similar in size to the state of Wisconsin, but Lake Michigan is a teeny bit closer to Wisconsin than Cali.
