There will be places in the world that will actually cool because of climate change, there will be places that do not show a temp change at all. Then there will be the prairies that actually see an INCREASE in precip as a result of this warming. But it doesn't change the fact that the climate has been changed, and the whole point of the Copenhagen conference is just to make sure that we don't pass the 2 C mark. The worst case scenario run by the ICPP is a 4 C change, thats with zero intervention, best case is a 2 C change.

2c more would probably still cause major grief, 4c would be a major disaster.
I posted this in another thread but it went unnoticed.

Interesting looking at the last 5 Novembers.
2005 - AH (6.1c) AL (-5.5c) ADT (-0.4c)
2006 - AH (-0.9c) AL (-4.8c) ADT (-6.3c)
2007 - AH (4.7c) AL (-7.9c) ADT (-1.6c)
2008 - AH (7.1c) AL (-2.8c) ADT (2.2c)
2008 - AH (9.1c) AL (-4.3c) ADT (2.4c)
AH = Average high
AL = Average Low
ADT = Average Daily Temperature
Looking farther back when they started keeping records.
From years 1893 to 2005 Calgary's temperatures in Nov were: AH (2.8c) AL (-8.9c) ADT (-3.1c)
In that time there has been 14 years in the plus side for ADT.
8/14 came since 1980, 4 of those came in the 2000,s. 2002 was the warmest at (2.7c) If you take away that one crazy cold November of 2006, Calgary has warmed almost 4c in the last decade for November.

I might try and find some time and do the data for every month, especially the winter months
