Apologies to the thread for the OT but I can't resist just one more...

One other fun effect of major melting of icecaps in increased tectonic activity as the earth adjusts to the changing weight distribution. In the distant past this has triggered major volcanic activity.

And one fun effect of major volcanic activity is that it causes global cooling, as the increased sulfur dioxide and particulate matter ejected into the atmosphere blocks the suns rays. When Tambora blew in 1815, it created the "year there was no summer", where mid summer frosts killed crops, causing famine in New England and northern Europe. Even Pinatubo in 1991 caused temps to drop for a few years. Interesting world we live in...

And now back to Oil Sands.. :)

LC,
Remember the summer of 1992 ? A virtual write off in southwestern Ontario.. it was mostly temps in the upper 60's F as i recall..

See Environment Canada stats.. Select Ontario, 1992 and monthly..
Note the avg temps for the summer months for Ontario 1992 and then check 1990 two years earlier.. It was a heck of a lot cooler in 1992. More than the world average cited below in fact.

This was why Mount Pinatubo Eruption
The eruption plume of Mount Pinatubo's various gasses and ash reached high into the atmosphere within two hours of the eruption, attaining an altitude of 34 km (21 miles) high and over 400 km (250 miles) wide. This eruption was the largest disturbance of the stratosphere since the eruption of Krakatau in 1883 (but ten times larger than Mount St. Helens in 1980). The aerosol cloud spread around the earth in two weeks and covered the planet within a year. During 1992 and 1993, the Ozone hole over Antarctica reached an unprecedented size.

The cloud over the earth reduced global temperatures. In 1992 and 1993, the average temperature in the Northern Hemisphere was reduced 0.5 to 0.6°C and the entire planet was cooled 0.4 to 0.5°C. The maximum reduction in global temperature occurred in August 1992 with a reduction of 0.73°C. The eruption is believed to have influenced such events as 1993 floods along the Mississippi river and the drought in the Sahel region of Africa. The United States experienced its third coldest and third wettest summer in 77 years during 1992.

Overall, the cooling effects of Mount Pinatubo's eruption were greater than those of the El Niño that was taking place at the time or of the greenhouse gas warming of the planet. Remarkable sunrises and sunsets were visible around the globe in the years following the eruption.

Rising water levels are pretty straight forward as the effects on coastal areas (and potable water !!) ... but beyond that I think it's far too complicated for even the 'experts' on any side to make too many solid predictions.. Many of them are going to look foolish (probably fortunate for most that they'll be dead in 2100 anyway) on both sides of the argument methinks..

Many coastlines are rising because of that tectonic activity :-[)

It's all a matter of time,...if water levels rise over a hundred years or so, do we care?

If things happen in a decade or two,...lots of people get flooded out,...but that is nothing unusual as that's been happening since before humans built their first wheel. And it has been predicted so buyer beware.

If things happen in a year or two the chit will really hit the fan and all the global warming advocates can say "I told you so" Parliament Hill in Ottawa will still be there giving all Canadians a headache and something to bitch about. The weeds in the lawn will probably grow faster with the higher pCO2 in the air :-)
