Lakes,Too,Feel Global WarmingThere's no doubt:In the last few decades,the average temperature on Earth has been higher than it has been in hundreds of years.Around the world,people are starting to measure the effects of global warming一 and trying to figure out what to do about it.Scientists recently used satellites to study the temperatures of lakes around the world,and they found that lakes are heating up.Between 1985 and 2009,satellites recorded the nighttime temperatures of the sur- faces of 167 lakes.During those 24 years,the lakes got warmer by an average of about 0.045 degreeCelsius per year.In some places,lakes have been warming by as much as 0.10 degree Celsius per year. At that rate,a lake may warm by a full degree Celsius in just 10 years.That difference may seem small一you might not even notice it in your bath.But in a lake,slightly warmer temperatures could mean more algae（水藻）,and algae can make the lake poisonous to fish.The study shows that in some regions,lakes are warming faster than the air around them.This is impor- tant because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well,scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That's going to be useful,since no country is too big or too small to ignore climate change.Scientists aren't the only ones concerned.Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it,especially by reducing theamount of greenhouse（温室）gases we put into the air.That's why the United Nations started the Framework Convention on Climate Change,or UNFCCC. Every year the convention meets,and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.Lakes seem to be warming faster in Asia.A:RightB:WrongC:Not mentioned

第一篇A Sunshade（遮阳伞）for the PlanetEven with the best will in the world,reducing our carbon emissions is not going to prevent global warming. It has become clear that even if we take the most strong measures to control emissions, the uncertainties in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time,resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough.Fortunately,if the worst comes to the worst,scientists still have a few tricks up their sleeves. For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the problem. Until now,that is a growing number of researchers are taking a fresh look at large-scale"geoengineering"projects that might be used to counteract global warming."I use the analogy of methadone,"says Stephen Schneider,a climate researcher at Stanford University in California who was among the first to draw attention to global warming."If you have a heroin addict,the correct treatment is hospitalization,and a long rehab. But if they absolutely refuse,methadone is better than heroin."Basically the idea is to apply"sunscreen"to the whole planet. One astronomer has come up with a radical plan to cool Earth:launch trillions of feather-light discs into space,where they would form a vast cloud that would block the sun's rays.It's controversial,but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earth's surface to counteract the warming produced by the greenhouse effect. Global climate models show that blocking just 1.8 percent of the incident energy in the sun's rays would cancel out the warming effects produced by a doubling of greenhouse gases in the atmosphere.That could be crucial,because even the most severe emissions control measures being proposed would leave us with a doubling of carbon dioxide by the end of this century,and that would last for at least a century more.According to the first two paragraphs,the author thinks that______.A:strong measures have been taken by the government to prevent global warmingB:It is impossible to prevent global warming by reducing carbon emissionsC:despite the difficulty,scientists have some options to prevent global warmingD:actions suggested by scientists will never be realized
