At +44c you don't NEED air conditioning to survive, but the same
can't be said for heat at -44c now, can it?
I quite agree that you don’t need air conditioning to stay alive at 44 C. But my question was, can you imagine anybody in North American being without air conditioning at 44 C? The answer is, probably not. In North America we are not used to being inconvenienced. If we had temperatures of 44 C, probably almost everybody would have air conditioning and our carbon foot print would be very high.
For that matter, let us consider heating. We have lived in Britain. In Britain, they keep indoor temperatures much lower than we do here. People wear sweaters indoor. As a result, my guess is that their carbon foot print would be a lot lower than our carbon foot print, even when outside temperatures are comparable (January in Birmingham and March in Toronto, for instance).
The fact is, we don’t like inconvenience of any kind in North America, we are used to soft life. In no other part of the world do people have it so good. That is why our carbon footprint is the highest in the world, much bigger than people in India or China.
