     The scene in the Hollywood movie The Day After Tomorrow, where global warming could soon turn the

global climate (气候) into a new ice age, may never occur, according to new research.

     The next ice age could be 15,000 years away, say European scientists who last month announced a

continuous record of 740,000 years of climate date (数据) obtained from the Antarctic ice.

     Scientists from 10 nations have now almost completely drilled through a 3,000-meter depth of ice high in

the Antarctic mainland. They figure out that the area where summer temperatures can fall to, has at least

900,000 years of snowfalls, kept as neatly as the growth rings of a tree. And the ice and air caught in each

layer (层) have begun to answer questions about the climates in the past.

     The results show that there have been eight ice ages in the past 740,000 years and eight warmer periods.

And by comparing the pattern of global conditions today with those of the past, the researchers reported in

Nature that the present warm period could last another 15,000 years.

     Research suggests that there is a very close connection between greenhouse gas levels and global average

temperatures. It also shows that carbon dioxide (二氧化碳) levels are the highest for at least 440,000 years.

     "If people say to you: the greenhouse effect is a good thing because we would go into an ice age

otherwise, our date say no, a new ice age is not hanging over our heads," said Eric Wolff from the British

Antarctic Survey." Now we have eight examples of how the climate goes in and out of ice ages … and you

can learn what the rules are that go into the climate models that tell us about the future."

     Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level. " In

440,000 years we have never seen greenhouse gas get as thick as it is today," said Dr Wolff.
