Climate change?

Question

What possible affects do increasing Earth temperatures have on climate change in Canada's North?

Answer 1

Bark beetles may become a big issue for Canada. Here in the US there are many areas where higher temperatures have allowed the bark beetle to extend it's range into areas it previously could not survive because of cold winter temperatures. The result is large stands of dead trees, in some cases up to 90% of the trees in an area have died. The forests on the San Bernardino mountains east of Los Angeles have been affected and now a wild fire is threatening to engulf the dead trees and destroy hundreds of homes and businesses.

Colorado forests have also been devastated by the bark beetle. Again the thing that has enabled the infestation is increased winter temperatures due to global warming.

If the bark beetle become established in Canada it may destroy the Canadian timber industry. Already 2 million hectors of Alberta pine forest is threatened.

Warmer weather even in cold areas is not always good news.

Answer 2

hmm dont know about all of Canada for certain, but these are my thoughts.

There is a current that runs from somewhere near Iceland or Greenland and travels all the way to I think India and back. This helps with the weather patterns on the East coast of the US and Canada.

now these ice... ugh things are melting, and im assuming is slowing the currents, if this trend continues, the ice "thing" will be gone and then no cold water to become part of the current, if this trend continues, this will greatly affect the weather to where either Canada will have temps of Southern US OR worse, will start the Ice Age. (Eskimos (sorry for not knowing the proper title for these natives) living in Texas) It has been theorized that the Earth at one point turned completely frozen, air became lethal, all sorts of bad stuff, then with the actual greenhouse gases (volcanic eruptions) the Earth started melting the ice creating water vapor and then rain to wash the acid out of the air and then brought life back to the Earth (also theorized that the Earth froze so slowly that the ice on top of the water was pure so that light could shine through and water plants were able to still conduct photosynthesis.

I dont know how this would effect Canadas weather directly and currently or within the near future, but its safe to assume that if the theories are right, there will be a suttle or violent (Depending which movie you like to go by) change.

Answer 3

Weather will become more unstable...

Expect the unexpected: whether the weather be hot or whether the weather be cold - the experts think it could polarise but they know whatever will happen the side effects in terms of what we experience will be very different to what we are used to...

Droughts, monsoons, tornados, hurricanes, hotter summers, drier winters, less moisture in the air one year, more than average the next - be surprised at nothing, and ready for anything no matter what: the met offices around the world don't know how to forecast what will happen, but they know it's coming...

The next El Nino event will be a great indicator as to what could happen

Answer 4

A lot less ice, the northwest passage will open up. The seasons will be more temperate, warmer in summer, more mild winters. The Polar Bear may die off. Millions of people trying to escape the dustbowl that the American mid-west will become will come north.

Answer 5

or to get away from the doomsday litany and unprovable pseudo gore science.....

take a good look at the population density of canada.. or find one of the earth at night pictures from space. 99% of the canadian population is within 50 miles of the us border. a few degrees warmer, and canadians can habitat farther north, increasing economic opportunity. of course thats assumeing that any global increase in temperature is uniform across the planet....
