Is our planet heating up? Are human beings to blame for climate change? The discussion on this subject has been heated, but what are scientists actually saying? At Reader's Digest, we decided to find it out.
Yes, it has, and even warmer. Greenland was forested between 450,000 and 800,000 years ago, so temperatures were considerably warmer then. There have also been other times of relatively high temperatures.
So why does the concern exist?
It's all about the speed at which temperatures are changing. But in the 20th and 21st centuries, especially since 1976, temperatures have probably risen more quickly than during any century in the past 1 ,000 years. Warming may bring improved crop production and other benefits to northern countries such as Canada or Russia. However, many species may not adapt to these conditions, and the one that is able to may cause a problem. The West Nile virus, first seen in North America nine years ago, infected about 4,000 people in the US in 2006. The mountain pine beetle, which is active during warmer winters, has already destroyed about 13 million hectares of Canada's forests, worth an estimated $6. 4 billion.
What is causing the warming?
IPCC has concluded that human activity is very likely responsible, by increasing the concentrations of greenhouse gases and thus the greenhouse effect. They argue the human contribution is nothing.
A. Some scientists, however, still disagree.
B. Has the planet ever been this warm before?
C. Has human behavior made the planet warm?
D. Temperatures have been changing all the time.
E. In the past, temperatures moved up or down gradually.
F. Mosquitoes have been moving northwards to higher places.
G. These questions have burst into newspapers, films and popular books.
Clara Barton，founder of the American Red Cross，gained worldwide honor for her dedication to easing human suffering and earned the nickname “Angel of the Battlefield.”
Barton was born into a liberal (开明的) freethinking family in 1821. Her elder brothers and sisters happily tutored her in math and reading, so when she entered school at three years old, she could read and spell three-syllable words. {#blank#}1{#/blank#}
Concerned about Barton's difficulty in making friends, her parents sent her to a boarding school, hoping it would make her more comfortable with her peers. {#blank#}2{#/blank#} Barton lost her appetite and cried constantly. After only one term, she had to be brought home. Then, Barton stayed out of school to nurse her older brother through a serious injury and also volunteered to care for poor families during a smallpox (天花）outbreak.

Shortly after Barton arrived back home in 1873，her sister died. {#blank#}5{#/blank#} When recuperating (休养）at a health facility in New York，she began planning for the establishment of an American wing of the International Red Cross.
