Did you see snow in your hometown last winter? Did you feel it was warmer than before? "There have been
21 warm winters in China since 1986," said scientists. They also said that in the past 100 years, as the global
(全球的) temperatures went up by 0.74 °C, the temperature in North China has climbed 1.4 °C in only 50
years.
China needs to take quick action to cut carbon dioxide (二氧化碳) emission (排放), because it's the main
reason for global warming. The good news is that China has seen the importance of going green. China set the
goal of cutting energy use by 20 and pollution emission by 10 in the 11th Five-Year Plan.
Can you slow global warming? Sure! You and your family can take steps to cut the amount of carbon
dioxide that is sent out into the air.
