Why is the weather changing so unusual?

AFP, Geneva. On Tuesday, the global temperature continued to rise this year, making 2000 one of the warmest years since 1860. According to the World Meteorological Organization, despite La Nina's "cooling effect", the global average temperature is still 0.6 degrees Celsius higher than that at the beginning of this century. The preliminary results show that the global average ground temperature in 2000 may be 0.32 degrees Celsius higher than the average temperature during 196 1-1990. 1999 ranks fifth among the warmest years since 140, and its annual average temperature also exceeds 196 1-1990. Professor godwin Obasi, Secretary-General of the World Meteorological Organization, said at the press conference: "The climate in 2000 reflects the continuation of the global warming trend that has been developing continuously since the 1990s." Obasi said: "This year is likely to rank fifth or sixth in the hottest year since 140". He went on to say: "At the same time, greenhouse gases continue to increase." The first thunderstorm recorded in Barrow, Alaska, USA was an extremely unusual weather event in 2000. The World Meteorological Organization pointed out: "Thunderstorm activities can better reflect the characteristics of climate warming." The World Meteorological Organization emphasized that in July, there were more than 75% stations in Bulgaria, and the highest temperature broke the previous record of 100 years, while the first fatal tornado occurred in Canada in 14 years. When asked if "these extreme weather can be regarded as greater evidence of global warming", Obasi said: "This is related to global warming." In 2000, there were more hurricanes and tropical storms in the Atlantic than in normal years (15, and only 10 in normal years). There are 22 typhoons and tropical storms in the Pacific Ocean, less than 28 in normal years. Mike Harrison is the head of the climate information and protection service of the World Meteorological Organization. He said: "El Nino may appear at the end of next year at the earliest." But he told reporters: "We can say with great certainty that there is no worry about the development of El Niñ o at present. But when the next El Niñ o will come, we can't give an accurate prediction. " El Nino is a large-scale replacement of sea water in the Pacific Ocean, which makes the sea water along the coast of South America extremely warm, while the sea water along the coast of Australia and New Zealand is extremely cold. It is believed that this phenomenon will lead to worldwide drought, flood, severe cold and forest fires. Last month, the United Nations international conference on implementing the Kyoto Protocol and limiting greenhouse gas emissions in The Hague, the Netherlands, broke down due to differences between the United States and the European Union.
