Research said to prove that greenhouse gases cause climate
change has been condemned as a {{U}}sham{{/U}} by scientists. A UN
report earlier this year said humans are to blame for global warming and there
is "little doubt" it is linked to man's use of fossil fuels. But other climate
experts say there is little scientific evidence to support the theory. In fact
global warming could be caused by increased solar activity.
Their argument will be outlined in a TV program called The Great Global Warming
Swindle raising major questions about some of the evidence used for global
warming. Ice core samples from Antarctica have been used as
proof of how warming over the centuries has been accompanied by raised
CO2 levels. But Professor Ian Clark at the University of Ottawa
claims that warmer periods of the Earth's history came around 800 years before
rises in carbon dioxide levels. The program also highlights how
there was a huge surge in carbon dioxide emissions, yet global temperatures fell
for four decades after 1940. The UN report, published in
February, was promoted as being backed by more than 2,000 of the world's leading
scientists. But Professor Paul Reiter said it was a "sham" given that this list
included names of scientists who disagreed with its findings. He also said his
name was removed from an assessment only when he threatened legal action against
the panel. "That is how they make it seem that all the top
scientists are agreed," he said. "It's not true." Gary Calder,
a former editor of New Scientist, claims clouds and solar activity are the real
reason behind climate change. "The government's chief scientific adviser Sir
David King is supposed to be the representative of all that is good in British
science, so it is disturbing that he and the government are ignoring a multitude
of evidence against the greenhouse effect being the main driver against climate
change," he said. Philip Stott, a professor of biogeography,
argues climate change is too complicated to be caused by just one factor,
whether CO2 or clouds. He said: "The system is too complex to say
exactly what the effect of reducing or increasing CO2 production
would be." "It is ridiculous to see politicians arguing over whether they will
allow the global temperature to rise by 2℃ or 3℃." The
documentary is likely to spark fierce criticism from the scientific
establishment.
单选题
A UN report on climate change is criticized for the following reasons
EXCEPT ______.
A. lack of convincing evidence for its theory
B. linking global warming to use of fossil fuels
C. including names of scientists who disagreed
D. refusal to use ice core samples from Antarctica
【正确答案】
D
【答案解析】此题需要阅读全篇文章。在第二段，一些气候学家说there is little scientific evidence to support the theory，此处的theory指的是global warming is linked to man's use of fossil fuels，因此把选项A和选项B否了。第六段和第七段说，联合国的报告声称得到2000多名科学家的支持，但有人质疑说名字造假。第四段说明联合国报告以冰核样本为证据证明全球变暖的同时二氧化碳水平升高，他们并没有拒绝使用这种样本。

B. Colder temperatures followed a surge in emissions of greenhouse
gases.
C. Global warming has nothing to do with increased CO2 levels at
all.
D. Criticism from the scientific establishment is reasonable and
acceptable.
