version
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.
② Greenhouse effect--- greenhouse gases-- we need those gases.

“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.
