I am 46 since a couple of days. Thanks God, I'm not a victim of the Alzheimer's disease so far. That is why, when seeing temperatures here in France dropping from +15°C last Friday down to -15°C today, I do believe in the Global Warming phenomenon : I never saw such of abrupt climate changes in this part of Earth since my memory is 'on'. That is why Al Gore' s message is worth listening, again and again...
