We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets. 

 Not long ago, My wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions(排放)of carbon dioxide(CO2)and other greenhouse gases that are trapping heat in our atmosphere. 

We decided to try an experiment. For one month we recorded our personal emissions of CO2. . We wanted to see how much we could cut back, so we went on a strict diet. The average US household(家庭)produces about 150 pounds of CO2 a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?

For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化)of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO2 emissions by 80 percent,” he said. 

Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.

 D. the average European household produces about 1,000 pounds of CO2 a month

B. Changing Our Habits Begins at Work

  C. Changing Climate Sounds Reasonable  

D. Reducing Emission of CO2 proves Difficult

More teachers are starting off the school year with letters to parents and students to introduce themselves and set a tone (基调) for the year. The letters are a good way to start positive communication with parents, several teachers told Education World.

“I think it’s professional, ”said Dorothy Peselli, an English teacher at Sparta High School in Sparta, New Jersay, Peselli, who gives out the letters the first day of school, told Education World. “It gives parents an image of you as a professional. If you start communication off in a positive manner, you will have the parents on your side when you need them.”

In her letter to parents, Peselli encourages them to call or e-mail her with specific concerns about their children. “I want to work as a team to make sure that your child becomes an independent lifelong learner,” Peselli wrote to parents last September. She also telephones the parents of all her students at the beginning of the year.

Peselli includes with the letter a classroom handbook (手册) listing plans and rules. And she requires that both parents and students read and sign statements (included in the letter) when they read the handbook. The student letter also lists needed supplies and gives encouragement. “Please come to class ready to work and learn. This will be an exciting year for all of us,” it says.

Last year, Peselli taught at a different high school and parents there were “shocked”, but appreciative, that she had so much contact with them. “I received roses and a thank-you note from one boy and his mother,” Peselli said. She wished her own children’s teachers would take the time to write notes as well. “I never got a letter home from any of my daughter’s high school teachers.” she said, “It would be nice to know the background of some of the people who are teaching my daughter.”
