This points to the issue that while the vast majority of measures to mitigate AGW save money (immediately, in the short- or long-run) or do not cost, measures to adapt to the consequences of AGW are extremely expensive – imagine building a dike around Florida.facebook.com/notes/west-antarctic-ice-sheet/proposal-for-the-creation-of-a-quebec-provincial-currency-unit-to-save-coastal-c/373261199364486
Proposal for the creation of a Quebec provincial currency unit to save coastal communities from threat of rising ocean levels
In my opinion it is going to cost trillions of dollars to do what needs to be done to protect towns like Truro, and Antigonish, Nova Scotia from the consequences of the cracking and sliding of a large part of the West Antarctic Ice Sheet and the land based Greenland Ice Pack into the ocean.
The province of Alberta attempted to create its own provincial currency unit during The Great Depression but enormous pressure was exerted to ensure that their experiment in monetary policy was unsuccessful.

The province of Quebec seems to be in much better position to create its own provincial currency unit without facing the massive backlash from the financial community and federal government that Alberta experienced.
Dr. James Hansen has stated that the last time that global temperatures rose by three degrees ocean levels rose by 25 meters over four centuries. Canada and the world are NOT yet prepared for ocean rise of one meter every twenty years.
Nearly one hundred million people in Bangladesh alone will become climate change refugees in the event of merely a one meter rise in ocean levels!
Now, it is not projected that the sea will rise 3 feet (one meter) in the next twenty years, but that is the high-end projection for 2100 in a business-as-usual scenario. Of course, once the process gets really underway within 100 years, I’m thinking it could be a 1 meter rise every 20 years thereafter (I can look that up, or ask my scientist friends).
Unfortunately there is already a lot of warming “in the pipes” from what we have already emitted – one study suggests 2.4C warming.* And our human industrial GHG emissions – which only slightly warm the earth/atmosphere, causing greater H2O evaporation and the great positive feedback from water vapor – could in a short time lead to enough warming to trigger positive feedbacks, such as melting snow & ice (which is now covering darker land and seas), leading to greater heat absorption and greater snow/ice loss, etc; and melting frozen permafrost and ocean hydrates, thereby releasing vast gigatons of methane (CH4) & CO2, leading to greater warming, leading to greater CH4 release, etc. These processes are already starting. It’s sort of like we are on the verge of tipping over that domino that will lead to a chain reaction beyond our control. So there is not a lot of time to mitigate so as to reduce extreme harms (many harms already being “in the pipes”), and since it takes years to implement all the GHG reducing, money-saving/no-cost meaures (it took us 22 years to reduce our GHG emissions cost-effectively 70% below our 1990 emissions – and there are still many things we can and should do), we need to really get to work fast.
I’m also hoping and praying that some of the strategies for drawing down CO2 can be ramped up and made effective and not too costly (and their risks reduced) – like biochar, etc.
We, or rather our progeny will still have to adapt as best they can in a vicious killer musical chairs world of diminshing life-sustaining resources – either one that is possibly life terminating in the long run (if we fail to mitigate), or one that is bad but liveable for at least a portion of humanity (if we mitigate), or perhaps one that is not too bad and liveable for most people (if we mitigate and the CO2 draw-down measures work).
AGW is a problem without a one silver-bullet solution. We need to do all we can, many many different thing – including taking hankies for wiping hands in public restrooms and reusable shopping bags – and offer constant prayers.
