As for the rest of your speculation..

Wind is quite predictable... with plenty of lead time..

They're usually spread out over a wide area, which evens out the
production of energy. Wind drops off in one area, it will take
minutes up to hours before wind velocity drop off reaches
the other end... The effect moderates even more as wind farms are
constructed over large geographic areas. (I.E. Overall wind farm
output increases or decreases gradually over time.)

As for predictability, a series of remote weather stations will do
nicely.

You still miss the point..
Large scale conversion of fossil fuels into CO2 == Coast line
submergence around the world.

At some point, governments will start imposing significant carbon
taxes on fossil fuels . Those taxes will help compensate for the
environmental damage that's coming down the pike. Once that occurs..
Fossil fuels will no longer be cheap..

The fossil fuel/ GW problem is of one the "Tragedy of Commons"
type problems that government is empowered to solve.

I.E.. "We the people of the United States, in order to form a
more perfect union, establish justice, insure domestic tranquility,
provide for the common defense, promote the general welfare,..."

I would say preventing 20% of US from be submerged falls in the
"promote the general welfare" category..

Another ridiculous statement..

Where was the balance *** when the US banned Slavery? or when
governments imposed minimum wage? or imposed retirement taxes? or
when OSHA imposed work safety rules? or when states imposed Workmans
Comp insurance? or when the EPA imposed pollution control standards?
or when the DOL imposed safety standards for mining? or when the FDA
imposed food inspection, labeling, handling, and content requirements?

In the summary... Citizens will always tradeoff increased costs in
return for tangible benefits to the society as a whole.

You still miss the point..

Fossil fuels are currently cheap because the market doesn't pay
the full costs for their transport and usage.

You're off you're rocker..
unfettered market crap got us into this GW mess.

Markets simply can't solve "Tragedy of Commons" type problems, since
they by definition, they don't pay all of the costs and suffer the
consequences.

Err no.. Taxing will do nicely..

Land based nukes are way.. way.. too dangerous.. their fixed
location make them easy to target and their resulting destruction
produces collateral effects well beyond the comprehension of most
humans. (You're included in that subset).

We already have several decades of data, and it's nothing like what
we're seeing now.. Right now (night time) it's in 70's.. tomorrow it
will be in 80's..

By the time you get around making up your mind.
it will be way to late to do anything meaningful.

Just in time for you to watch N. Korea and/or Osama and/or Iran
and/or whomever is the new kid on Nuke block. Blackmails Canada with
destruction of one or more of it's nuclear power plants. What will
you do? Pay up.. or watch them blow one up? How about next year?
And the year after that? Are you prepared to relocate the entire
human population from one of Canada's provinces when you don't pay up?

Oh.. while your at it.. don't forget to compensate the US for the
isotope laden fallout that crosses the boarder. Hmmm.. I think half
of Alberta's oil sands will do quite nicely.

P.S. Don't forget..it will be several centuries before the areas
affected will be safe enough to repopulate.
