NEW YORK, Wednesday (AAP). — Weather satellites sweeping across the northern hemisphere have come up with a surprise: the permanent snow and ice cap has increased sharply, Associated Press reported. The finding is cited as one more indication of what some climatologists believe to be a basic change in the world’s climate, a cooling
The location and duration of snow and pack-ice fields constituted the most important seasonal variable in the earth’s heat balance, the two scientists wrote in Science, journal of the American Association for the Advancement of Science.
The Kukla report is cited by Dr F. Kenneth Hare, of the University of Toronto, a leading climatologist, who says the big ice expansion preceded the coldest Canadian winter yet recorded. In the winter of 1972, Dr Hare said in an interview, temperatures were below normal for the entire year over the entire country. This had never happened before. For the north-eastern third of the country, Dr Hare said, it was the coldest year on record, in many places coldest by a wide margin. In many areas, he continued, there were as many as 19 consecutive months of below normal temperatures. The earliest serious records began in 1840, Dr Hare noted. So for 130 years there has not been anything like it.
“I don’t know what caused this”, he said. “But the climate has in fact shifted into a more extreme phase”.
In the past few years, with the cooling of the earth and the southward movement of the subtropical high-pressure areas, drought frequency had been increasing in India. If droughts returned to India with a frequency like that which prevailed at the turn of the century, but with a population swollen four fold, the human and political consequences would be enormous.
