Is the Isthmus of Chignecto The Canary in the Coal Mine for Climate Change?

[DennisPTate]

I believe that the geography of the Isthmus of Chignecto between Nova Scotia and
New Brunswick is serving as the proverbial "Canary in the Coal Mine" when it comes to
the topic of Stabilization of the Climate.




"Physics question related to the geography of the Bay of Fundy?"

"If average ocean levels were to rise by ten centimeters.... .would
the multiplier effect of the geography of the Bay of Fundy continue?

The fact that the Bay of Fundy funnels tidal waters plus......
it is over 170 miles long, (274 kms), it produces high tide level that are tenX to fifteenX over the difference in tidal waters where I live.

So... could high tide levels near TRuro, N. S. to Moncton, N. B. be up by a meter or more if average ocean levels were to rise by ten centimeters?" [Dennis Tate, March 7, 2021]

Here is an image that will help you to understand this situation better. Because the Bay of Fundy has a FUNNELLING effect on high tide waters, forcing them into a more and more narrow area, the World's Highest Tides occur in the Bay of Fundy. So, if a large amount of ice where to crack and slide off the Land Based Greenland Ice Sheet and if AVERAGE ocean levels were to rise by ten centimeters, I would expect that the area of the Bay of Fundy that now experience a 10X to 15X MULTIPLIER effect on high tide levels, could well be up by those ten centimeters X ten or one hundred centimeters.

That much of a rise in high tide levels on the Isthmus of Chignecto would tend to liquify the soil of the Isthmus of Chignecto and wash it into the Bay of Fundy.

An online engineer has proposed a rather brilliant solution:

Mervyn DePendleton) :

"Well from an engineering point of view if it was a sure thing and time would allow the answer is not going to be try to air condition the Antarctic. I would think in terms of cutting a relief channel. That would be between Sackville and Amherst would be to excavate a canal that would only start to receive water when the tide is up approximately the half of normal height and this canal would have to continue sloping down and terminate in the Gulf of St. Lawrence across from PEI.

No doubt such an undertaking would get bad reviews from a lot of environmentalist but it could save some of the low level human habitation on the banks of the Bay of Fundy. When I visited the area I remember on the N.B. side that there was a lot of high ground as you went inland from the shore of the Bay.

Another approach would be to think like the Seaway Project where Cardinal and Morrisburg and lots of farms and places on the Canadian side of the St. Lawrence were moved and the land flooded with the power dam near Cornwall. The idea with Fundy would in the energy extraction view would be to tell all the low land people to hit it, your property is ruined. At the sea entrance somewhere more in the direction toward St. John to create a one way valve type mechanism. Let the tide water come rushing and don't let it leave right away. When the tide forces have receded then release the water through turbines to generate electricity. From half tide to low tide and back to just coming back again all the stored water has to be used. It might also be possible to get some energy out of the water when it is rushing in at high tide.

I'm sure some high math and some good engineers could get the greatest benefit possible from conditions we otherwise cannot control. Also do not give up on the earth getting ever hotter as it may well be cooling for a while before us. All the end of world alarmist like Paul Ehrlich and the peak oil we would be burning camel dung by 1999 alarmist have all failed miserably in their predictions. The big problem with all of them is that they are trying to tell us something about the future. Conservative minded people know the secret, if you want to predict the future get out in front of it and do something to shape the future with your own hands.
