The ability to predict the warming and cooling of the Pacitic is of immense importance’．The 1997 El Nino，for example，caused an estimated$20 billion in damage worldwide，offset by beneficial effects in other areas，said David Anderson，of the European Centre for Medium．Range Weather Forecasts in Reading England．The 1877 El Nino，meanwhile，coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China。prompting the development of seasonal forecasting，Anderson said．
When El Nino hit in 199 1 and 1997．200 million people were affected by flooding in China alone．according to a 2002 United Nations report．
While predicting smaller E1 Nino events remains tricky．the ability to predict larger ones should be increased to at least a year if the new method is confirmed．
E1 Nino tends to develop between April and June and reaches its peak between December and February．The warming tends to last between 9 and 1 2 months and occurs every two to seven years·
The new forecasting method does not predict any major El Nino events in the next two years, although a weak warming toward the end of this year is possible．
E1 Nino n．厄尔尼诺现象
Equatorial adj．赤道的
Occurrence n．发生
Meteorologist n．气象学家
Offset v．抵销
Lead adj．提前的
Monsoon n．季风
Tricky adj．难以捉摸的

Blasts from the past
1 Volcanoes were more destructive in ancient history．Not because they were bigger, but because the carbon dioxide they released wiped out 1ife with greater ease．
2 Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions．Not a11 volcanic eruptions killed off large numbers of animals，but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock．To his surprise，the older the massive volcanic eruptions were，the more damage they seemed to do．
3 Wignall calculated the“ killing efficiency ”for these volcanoes by comparing the proportion ．ion of life they killed off with the volume of lava that they produced．He found that size for size，older eruptions were at least 1 0 times as effective at wiping out life as their more recent rivals．
4 The Permian extinction，for example，which happened 250 million years ago，is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe．Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide．The global warming that followed wiped out 80 per cent of all marine genera at the time。And it took 5 million years for the planet to recover．
