    Snow and gathering clouds may be signs of global warming. The average temperature on Earth for last year was the second warmest since written records began 140 years ago. The global average surface temperature in 2001 was 14.42 degrees centigrade, the World Meteorological Organization said. The record, set in 1998, was 14.58 degrees centigrade. “Temperatures are getting hotter, and they are getting hotter faster now than at any time in the past, ” said Michel Jarred, a WMO official. Carbon dioxide(二氧化碳) produced from burning fuels is the most common of the so-called greenhouse gases. The growing concentration(集中) in the atmosphere of these gases is thought to be warming the Earth. “Most of the causes of global warming are due to human action, ” said Ken Davidson, director of WMO's climate programmed department. Every year, large amounts of gases produced by factories, cars and burning trees hold in too much heat and cause global warming. Many scientists believe the warming, if not stopped, will cause extreme climate changes this century. MILY: 'Times Throughout the world, the spreading of particular diseases and other threats(威胁) to human health depend largely on local climates. Extreme temperatures can directly cause loss of life. Warm temperatures can increase air and water pollution, which in turn can harm human health. In the Earth's atmosphere there are tiny amounts of gases called greenhouse gases. These gases hold in the heat that comes up from the sun-warmed Earth. As cities have increased in size and population, factories and industries in the world have grown. People need more and more electricity, cars and other things. So more greenhouse gases have been added to the atmosphere. This causes more heat to be trapped than in the past. This is called the greenhouse effect.
