Snowfalls are now just a thing of the past March 20, 2000Britain's winter ends tomorrow with further indications of a striking environmental change: snow is starting to disappear from our lives. Global warming, the heating of the atmosphere by increased amounts of industrial gases, is now accepted as a reality by the international community. Average temperatures in Britain were nearly 0.6Â°C higher in the Nineties than in 1960-90, and it is estimated that they will increase by 0.2C every decade over the coming century. Eight of the 10 hottest years on record occurred in the Nineties. Heavy Snow Causes Disruptions in Britain January 6, 2010London, a city known for its low tolerance for snow, was buffeted by an unusually thick snowfall on Wednesday, the heaviest in more than 20 years. The snow and ice shut down railroad services, airports and schools across southern England and brought travel nearly to a halt on major highways. As deep as eighteen inches in some areas, the snowfall on Wednesday was the biggest in southern England since 1987. Two of London’s three airports, Gatwick and Luton, shut down entirely, and delays were reported at the largest, Heathrow.
