Britain's winter ends tomorrow with further
indications of a striking environmental change: snow is starting to disappear
from our lives.
Sledges, snowmen, snowballs and the
excitement of waking to find that the stuff has settled outside are all a
rapidly diminishing part of Britain's culture, as warmer winters - which
scientists are attributing to global climate change - produce not only fewer
white Christmases, but fewer white Januaries and Februaries.
The first two months of 2000 were virtually
free of significant snowfall in much of lowland Britain, and December brought
only moderate snowfall in the South-east. It is the continuation of a trend
that has been increasingly visible in the past 15 years: in the south of
England, for instance, from 1970 to 1995 snow and sleet fell for an average of
3.7 days, while from 1988 to 1995 the average was 0.7 days. London's last
substantial snowfall was in February 1991.
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 0.6°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.
However, the warming is so far manifesting
itself more in winters which are less cold than in much hotter summers.
According to Dr David Viner, a senior research scientist at the climatic
research unit (CRU) of the University of East Anglia,within a few years winter
snowfall will become
"without experiencing one of the greatest
joys and privileges of living in this part of the world - open-air
skating".
Warmer winters have significant environmental
and economic implications, and a wide range of research indicates that pests
and plant diseases, usually killed back by sharp frosts, are likely to
flourish. But very little research has been done on the cultural implications
of climate change - into the possibility, for example, that our notion of
Christmas might have to shift.
Professor Jarich Oosten, an anthropologist at
the University of Leiden in the Netherlands, says that even if we no longer see
snow, it will remain culturally important.
"We don't really have wolves in Europe any more, but they are
still an important part of our culture and everyone knows what they look
like," he said.
David Parker, at the Hadley Centre for
Climate Prediction and Research in Berkshire, says ultimately, British children
could have only virtual experience of snow. Via the internet, they might wonder
at polar scenes - or eventually "feel"
virtual cold.
Heavy snow will return occasionally, says Dr
Viner, but when it does we will be unprepared. "We're really going to get caught out.
Snow will probably cause chaos in 20 years time," he said.
The chances are certainly now stacked against
the sortof heavy snowfall in cities that inspired Impressionist painters, such
as Sisley, and the 19th century poet laureate Robert Bridges, who wrote in "London Snow" of it, "stealthily and perpetually settling
and loosely lying".
Not any more, it seems.
