Quote from Pension_Admin:
Interesting. Could you please elaborate on the affect of the melting permafrost?
If it's going to affect the housing needs, does it mean people from the USA should start investing in Canadian real estate to capture the profit from supply and demand imbalance in our housing market?
I personally live in Toronto and I believe it's always fun to know what people from other countries think our concerns are.

Canada is in the deep, which ever way you look at it.
Primarily this situation is from a global warming point, and specifically looking at the Cryosphere. (all climate system components include the atmosphere, hydrosphere, cryosphere, biosphere, and lithosphere).
The Cryosphere is permanent and seasonal ice cover, including frozen water (e.g. in Canada and Siberia)), seasonal snowfalls, glaciers, polar ice caps, and permafrost.
Permafrost (permanently frozen ground water) contains around 500 billion tones of greenhouse gasses.
Relaxation times for the Cryosphere are tens of millennia.
There is evidence that the permafrost is melting in Canada where houses are sinking into the ground.
It is now thought that the Cryosphere plays and important role in global warming, because it has a high albedo and low thermal conductivity, however this effect is localized.
so what's the problem?
The problem is that it may be a positive feedback mechanism (i.e. irreversible)
1. melting cryosphere reduces the Earth's albedo
2. trapped greenhouse gasses are released
3. elevated Earth temperature
4. elevated sea levels
so what are we talking about?
this is all about the transfer of energy which is neither created nor destroyed
Actual science cannot argue with the increase in carbon dioxide at Mona Loa in Hawaii, where concentrations of carbon dioxide have gone from 315ppm in 1955 to 370ppm in 2001.
There is another problem!
The Hydrosphere, where the Oceanic Conveyor belt is on the verge of collapse
The thermosaline circulation occurring in the deep ocean are responsible for the heating of Northern Europe.
If the conveyor belt stops, ice age like temperatures will occur around Europe, but higher temperature will be seen around the globe
conclusion
1. Canada is screwed
2. Your survey of reserves may not be accurate as they take current and previous consumption into consideration only
3. Canada will have to pump more oil and gas to keep everything nice and warm.
4. Canada will run out of reserves quicker than the current thinking
5. One have to find solutions to problems that this generation and previous ones have created, and not leave them to the future generations (which is what the survey of reserves suggests)
second conclusion
1. We are having to find solutions to problems in our generation, that have been handed down to us by the generations above us, and we cannot continue this passifism of "It's not my problem."
2. The point is that we have to find solutions for future problems now.
Consider the analogy: they invented the car and aeroplane 100 years ago, and we use these instruments today, as a solution for addressing today's challenges. So we should take the responsibility to do the same for our future generations, in order to safeguard their future.
