"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 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 down global warming? Sure! You and your family can take steps to cut the amount of carbon dioxide that is sent out into the air.

Wear used clothes. Wearing your brother's, sister's or dad's old T-shirt means you save the energy.                                                                       
Change your light bulbs (燈泡). Use energy-saving light bulbs. And don't forget to turn off the lights when you leave a room and turn off your television and computer when they are not in use!
Ride the bus. Taking a bus saves a lot of oil every year.
Say no to plastic bags. The next time your parents go to the market, ask them to use baskets
Open a window. Don't use the air conditioner, and let some fresh air in. When you have to use the conditioner, set the temperature higher in the summer and lower in the winter to save energy.
Make small changes in your daily life. Don't use paper cups, bags and boxes.
