CLIMATE CHANGE. Snow, Arctic temperatures and big freeze in Paris, France. A mattress used as a toboggan lies near to the funicular train track going up, in the snow, to the Sacre-Coeur overlooking over Paris. Temperatures plummeted below zero, as low as -9. Very rarely, certainly not for decades, that Paris has experienced such freezing cold weather. Snow normally disappears in a couple of hours, this time it stuck around for days. Freak weather conditions and climate change can often be attributed to global warming and the ozone layer.
