London Times August 8 1997 Pollution puts Earth on course for hottest year BY NICK NUTTALL, ENVIRONMENT CORRESPONDENT SCIENTISTS predict that the Earth will have record temperatures this year and are linking the increase to pollution. Researchers at the Meteorological Office's Hadley Centre for Climate Prediction said yesterday that on average the world's temperatures could be more than 0.7C hotter this year than when records began in the late 19th century. The Earth was at its hottest in 1995, followed by 1990, 1991, 1994, 1988, 1983, 1987, 1996 and 1989. Geoff Jenkins, head of the centre's climate prediction programme, said: "We are almost certainly going to exceed the average global temperatures of 1990. It now looks as if we will go higher, challenging the 1995 record year." He said part of the increase would be caused by El Nino, a cyclical climatic event that begins in the eastern Pacific, triggering violent weather in Asia and Australasia. But Dr Jenkins said that had always been an influence on global weather and that to reach another record-breaking year there had to be an additional cause. He said that global warming, caused by pollution, could account for the higher temperatures of the 1990s. "Taking one year on its own is not significant. But this year will certainly continue the run of warm years in the 1990s." The researchers compare average global temperatures with a 30-year running average from 1960 to 1991. The hottest year on record, 1995, was 0.38C higher than the 30-year average. This compares with a temperature of about minus 0.3C in the late 19th century, making 1995 about 0.7C higher than then. "These temperature differences may sound like nothing," Dr Jenkins said. "But the temperature difference between the depths of the last Ice Age, about 20,000 years ago, and this century is about five degrees. The rise we expect over the next 100 years is three degrees." Yesterday more than 160 countries concluded preliminary talks in Bonn on curbing global warming. But America, under pressure from industry, worked with Japan to block any agreement on cutting emissions of carbon dioxide, the main global-warming gas.
