THE EARTH IS BECOMING WARMER-BUT DOES IT MATTER?During the 20th century the temperature of the earth rose about one degree Fahrenheit. That probably does not seem much to you or me, but it is a rapid increase when compared to other natural changes. So how has this come about and does it matter? Ea rth Care’s Sophie Armstrong explores these questions.There is no doubt that the earth is becoming warmer (see Graph 1) and that it is human activitythat has caused this global warming rather than a random but natural phenomenon.All scientists subscribe to the view that the increase in the earth's temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy. Some byproducts of this process are called "greenhouse" gases, the most important one of which is carbon dioxide. Dr Janice Foster explains: "There is a natural phenomenon that scientists call the 'greenhouse effect'. This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth. Without the 'greenhouse effect', the earth would be about thirty-three degrees Celsius cooler than it is. So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. It means that more heat energy tends to be trapped in the atmosphere causing the global temperature to go up."We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years. It was a scientist called Charles Keeling, who made accuratemeasurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997. He found that between these years the carbon dioxide in the atmosphere went up from around 315 parts to around 370 parts per million(see Graph 2).All scientists accept this data. They also agree that it is the burning of more and more fossilfuels that has resulted in this increase in carbon dioxide. So how high will the temperature increase go? Dr Janice Foster says that over the next 100 years the amount of warming could be as low as 1 to 1.5 degrees Celsius, but it could be as high as 5 degrees.However, the attitude of scientists towards this rise is completely different. On the one hand, Dr Foster thinks that the trend which increases the temperature by 5 degrees would be a catastrophe. She says, "We can't predict the climate well enough to know what to expect, but it could be very serious." Others who agree with her think there may be a rise of several metres in the sea level, or predict severe storms, floods, droughts, famines, the spread of diseases and the disappearance of species. On the other hand, there are those, like George Hambley, who are opposed to this view, believe that we should not worry about high levels of carbon dioxide in the air. They predict that any warming will be mild with few bad environmental consequences. In fact, Hambley states, "More carbon dioxide is actually a positive thing. It will make plants grow quicker; crops will produce more; it will encourage a greater range of animals - all of which will make life for human beings better."Greenhouse gases continue to build up in the atmosphere. Even if we start reducing the amount of carbon dioxide and other greenhouse gases, the climate is going to keep on warming for decades or centuries. No one knows the effects of global warming. Does that mean we should do nothing? Or, are the risks too great? WHAT CAN WE DO ABOUT GLOBAL WARMING?Dear Earth Care,I am doing a project on behalf of my school about global warming. Sometimes I feel that individuals can have little effect on such huge environmental problems. However, 1 still think people should advocate improvements in the way we use energy today. As I'm not sure where to start with my project, I would appreciate any suggestions you may have.Thank you!Ouyang GuangDear Ouyang Guang,There are many people who have a commitment like yours, but they do not believe they have the power to do anything to improve our environment. That is not true. Together, individuals can make a difference. We do not have to put up with pollution. The growth of the greenhouse gas, carbon dioxide in the air actually comes as a result of many things we do every day. Here are a few suggestions on how to reduce it. They should get you started with your project.1 We use a lot of energy in our houses. It is OK to leave an electrical appliance on so long as you are using it - if not, turn it off! Do not be casual about this. So if you are not using the lights, the TV, the computer, and so on, turn them off. If you are cold, put on more clothes instead of turning up the heat.2 Motor vehicles use a lot of energy- so walk or ride a bike if you can.3 Recycle cans, bottles, plastic bags and newspapers if circumstances allow you to. It takes a lot of energy to make things from new materials, so, if you can, buy things made from recycled materials.4 Get your parents to buy things that are economical with energy - this includes cars as well as smaller things like fridges and microwaves.5 Plant trees in your garden or your school yard, as they absorb carbon dioxide from the air and refresh your spirit when you look at them.6 Finally and most importantly, be an educator. Talk with your family and friends about global warming and tell them what you have learned.Remember - your contribution counts! Earth Care。
