Canada

Website aims to educate Americans about Canada [Globe & Mail]:

Oh sure, you hear about how everyone plays hockey in Canada, gets to the rink by dogsled and then goes home to an igloo.

But many myths about Canadians that circulate in the United States aren't nearly so silly or harmless.

...


For the record, I don't own a dogsled or igloo (and, in fact, have never used either). Similarly, I don't know Jimmy, Sally, or Suzy.

Hockey is practically a religion though.

Tipping Point

The rocket scientists at NASA say Tropical Deforestation Affects Rainfall in the U.S. and Around the Globe:

...

Deforestation in the Amazon region of South America (Amazonia) influences rainfall from Mexico to Texas and in the Gulf of Mexico. Similarly, deforesting lands in Central Africa affects precipitation in the upper and lower U.S Midwest, while deforestation in Southeast Asia was found to alter rainfall in China and the Balkan Peninsula. It is important to note that such changes primarily occur in certain seasons and that the combination of deforestation in these areas enhances rain in one region while reducing it in another.

And even more scary, Global warming 'past the point of no return':

A record loss of sea ice in the Arctic this summer has convinced scientists that the northern hemisphere may have crossed a critical threshold beyond which the climate may never recover. Scientists fear that the Arctic has now entered an irreversible phase of warming which will accelerate the loss of the polar sea ice that has helped to keep the climate stable for thousands of years.

They believe global warming is melting Arctic ice so rapidly that the region is beginning to absorb more heat from the sun, causing the ice to melt still further and so reinforcing a vicious cycle of melting and heating.

...

In September 2002 the sea ice coverage of the Arctic reached its lowest level in recorded history. Such lows have normally been followed the next year by a rebound to more normal levels, but this did not occur in the summers of either 2003 or 2004. This summer has been even worse. The surface area covered by sea ice was at a record monthly minimum for each of the summer months - June, July and now August.

...

Current computer models suggest that the Arctic will be entirely ice-free during summer by the year 2070 but some scientists now believe that even this dire prediction may be over-optimistic, said Professor Peter Wadhams, an Arctic ice specialist at Cambridge University.
