I see. On the other hand a small rain can flood Athens whereas in Belgium everything is business as usual even in a -10C snowfall.

I'm wondering, is it that 3000 deaths have been clearly attributed to the heat wave, or is it that 3000 people have died in France during this period?

It is difficult to estimate with complete accuracy the deaths from heat. For example: an old person comes to the hospital with respiratory problems. After a while the doctors were unable to save him and he expires.
Were the respiratory complications that made him go to the hospital and eventually killed him a result of heat or not? (assuming he/she had a history of respiratory or heart problems). Difficult to say with certainty, I'd think.

quote: Actually... An increase in global temperatures is likely to result in a new global iceage as increased evaporation slightly changes the ocean's salinity causing ocean currents to change to a more east-west orientation instead of the tropics to the polls style currents we have now.
Supposedly, as the salinity increases the density of the surface water increases and the ocean currents dive deeper instead of staying mostly on the surface as they currently do. This means less heat energy will make it to the extreme north or south thus resulting in a cooling trend. This is what is thought to have caused the mini-ice age after the midevial warm period. |
There has to be some mechanism in place since temps were higher during past inter-glacials when the only "greenhouse" gases being emitted by humans came from the orifices of Neandertals. 
About a 1,000 years after the last ice advance ended, it is believed Lake Agassiz, a large glacial lake that surpassed even the Great Lakes in volume located just to the NW of Lake Superior broke through a retreating glacial dam flooding down the St Lawrence into the Atlantic. The result was a flood of fresh water right into the Atlantic conveyor belt, the Sargasso Sea and the warmer and saltier current heading for England, shutting it down and plunging NE America and Western Europe back into the ice age for another 1,000 years.
There's also evidence from Western Europe of an ice advance starting up in as little as 20 years. This was detected from pollen in France in layers ~115,000 years old. Evidence of extensive volcanic activity is lacking, so something caused an ice advance in a very short amount of time.
