Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
1.By saying “ we are knocking at the door immortality”, Michael Zey means_____.
A. they believe that there is no limit of living
B. they are sure to find the truth about long living
C. they have got some ideas about living forever
D. they are able to make people live past the present life span
2.Donald Louria’s attitude toward long living is that_____.
A. people can live from 120 to 180
B. it is still doubtful how long humans can live
C. the human body is designed to last about 120 years
D. it is possible for humans to live longer in the future
3.70. The underlined “ it” (Para. 4) refers to_____.
A. a great push
B. the idea of living beyond the present life span
C. the idea of living from 200 to 300
D. the conservative estimate
4.What would be the best title for this text?
A. Living longer or not
B. Science, technology and long living
C. No limit for human life
D. Healthy lifestyle and long living.
