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.

Since the climate will keep on warming for decades even centuries, is there anything we can do? The answer is for sure. As individuals we should do our part. We can make small changes like taking public transport to reduce greenhouse gas emission. In addition, we can choose to buy the recycled products, use environmentally friendly shopping bags, etc. As for the government, strict laws concerning global warming have to be put into effect. Besides, it’s better for the government to encourage people to find and use more renewable energy.

“Global warming is reducing the amount of food for penguins so that they can’t find enough to eat，” scientist Shaye Wolf said.
Turning up the heat
Humans may be directly responsible for the continent’s temperature changes, according to a new study in the journal Nature Geoscience.Temperatures in Antarctica usually do not go above freezing, or 32 degrees Fahrenheit.
返回
Scientists are concerned about the possibility that
Antarctica’s ice may melt more over time. The icy continent is about 5 million square miles. It is covered by glaciers and an ice cap(冰冠)about 7,100 feet thick. If the ice melts, that could cause sea levels to rise around the world. Higher sea levels could lead to dangerous flooding in some countries.

Horses started out small, about the size of a small dog. What’s surprising is that after they first appeared, they then became even smaller and then dramatically(戏剧性地) increased in size, and that exactly corresponds(符合) to the global warming event, followed by cooling. “It had been known that mammals were small during that time. And it was warm, but we hadn’t understood that temperature specifically was driving the evolution of body size.” Dr Bloch said in the “Science” journal.

Global Warming Could Make Us Shorter “Global warming could make humans shorter,” warn scientists who claim to have found evidence that it caused the world’ s first horses to shrink(收缩) nearly 50 million years ago. In fact, a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammals(哺乳动物)—horses, in this case, the last time the world heated up.

【参考范文】 Warming climates are increasing the uncertainties of life for all organisms. A long-term warming trend would change the distribution of life on the planet as colder habitats become smaller and warmer ones expand. Some species would become more common, others would become rarer. We cannot say for sure which species will become extinct—or when.Plants and animals that are highly adapted to extreme climates are most likely to be the first and most drastically affected.
英语(RA-GZ)- 选修6
The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago. “As temperatures went up their size went down, and at one point they were as small as a house cat,” said Dr Jonathan Bloch, head of the Florida Museum of Natural History, which was quoted by the “Daily Mail” as saying. The scientists say that the current warming could have the same effect on mammals and could even make humans smaller.
