[ RadSafe ] The Great Global Warming Swindle

I live in Canada also, and am concerned about global warming and the melting 
of the polar "ice caps". Our house is over 100 m above sea level but houses 
below us in Vancouver and in other cities on the three coasts are concerned 
because they will be under water.
