4. Greenhouse gases continue to build up in the atmosphere.
5. George Hambley believes that global warming will do good rather than harm to the earth.
Researchers say these changes are having severe effects on animals such as penguins, seals and polar bears. Changes in temperature and wetness in the air can also affect the reproduction of some reptiles and amphibians. For example, the sex of baby painted turtles is linked to the average temperature in July. Scientists say even small temperature increases can threaten the production of male turtles. In Europe, scientists say warmer temperatures are affecting the spring and autumn seasons.
What’s worse, the glaciers (冰川) of the South Pole are beginning to crack (破裂).

I think an increase of five degrees would be a catastrophe and could be very serious.
Dr Janice Foster
I believe we shouldn’t worry about high levels of carbon dioxide in the air. any warming will be mild with few bad environmental consequences. more carbon dioxide is actually a positive thing, which will make life for human beings better.

3. Is the “greenhouse effect” entirely harmful?
Without the “greenhouse effect”, the earth would be about thirty-three degrees Celsius cooler than it is.
The attitudes of scientists towards this rise are completely different. Some think that the trend would be a catastrophe while some are opposed to this view, and believe that any warming will be mild with few bad environmental consequences.
earth would be about thirty-three degrees Celsius cooler than it is.
