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.

Questions 184-188 refer to the following article.
President Barack Obama has issued his call to put global warming at the top of the international
agenda, pledging to push for coordinated action by the world's biggest countries to tackle problem of climate change.
In the speech, the US president on Tuesday laid out a three-pan plan to deal with climate change using the power of his office.
He outlined a strategy to cut the US's carbon pollution by reducing emissions from coal-fired power plants; to prepare the US for the impact of climate change, such
as the super storm that ravaged the New Jersey coastline last year, and to lead the world by example in combating changing climate.
"While no single step can reverse the effects of climate change, the president believes we have a moral obligation to our kids to leave them a planet that's not polluted and White House official said.
The coal industry said the proposals could prove devastating-----shares in US coal mining companies have been falling sharply-but Mr. Obama ' s speech was being watched closely around the world.
In Europe, where the Eurozone crisis has pushed the
climate change agenda firmly into the political background, environmental campaigners said they hoped Mr.Obama's speech would puncture arguments tackling global warming as bad for the economy.”If you have got the US and China moving, then the argument that the EU is going it alone clearly doesn't stand up to scrutiny anymore," said Tom Brookes of the European Climate Foundation.
The president said he would seek to expand new and existing international initiatives,including bilateral initiatives with China, India and other big emissions countries.
What was the main point of Obama ' s speech?
A. to call for actions to tackle the problems of climate change
B. to co-ordinate for the implementation of international agenda
C. to lay out a plan for environmental problems
D. to find reasons for recent global warming

New research from NASA scientists suggests emissions of black soot after the way sunlight re- flects off snow.According to a computer simulation,black soot may be responsible for 25 percent of observed global warming over the past century. Soot in the higher latitudes（维度）of the Earth,where ice is more common , absorbs more of the sun's energy and warmth than an icy,white background. Dark-colored black carbon,or soot, absorbs sunlight,while lighter colored ice reflects sunlight.Soot in areas with snow and ice may play an important role in climate change.Also,if snow and ice covered areas begin melting,the warming effect increase,as the soot becomes more con-centrated on the snow surface.“This provides a positive feedback,as glaciers and ice sheets melt, they tend to get even dirtier.”said Dr. James Hansen,a researcher at NASA's Goddard Institute for Space Studies,New York.Hansen found soot's effect on snow albedo（反照率）,which may be contributing to trends to-ward early springs in the Northern Hemisphere,such as thinning Arctic sea ice and melting glac-iers permafrost. Soot also is believed to play a role in changes in the atmosphere above the oceans and land.“Black carbon reduces the amount of energy reflected by snow back into space,thus heating the snow surface more than if there were no black carbon,”Hansen said. Soot's increased absorp-tion of solar energy is especially effective in warming the world's climate.“ This forcing is unusual-ly effective,causing twice as much global warming as a carbon-dioxide forcing of the same magni-tude.”Hansen noted.Hansen cautioned,although the role of soot in altering global climate is substantial,it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century .Such gases are expected to be the largest climate forcing for the rest of the century.The researchers found that observed warming in the Northern Hemisphere was large in the winter and spring at middle and high latitudes. These observations were coherent with the researchers' climate model situations,which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight. What is the main cause of climate warming during the past century?A: Soot.B: Snow.C: Greenhouse gases.D:.Wind.

问答题Not so long ago, people talked about global warming in apocalyptic terms—imagining the Statue of Liberty up to its chin in water or an onslaught of tropical diseases in Oslo. Recently, however, advances in our understanding of climate have moved global warming from a subject for a summer disaster movie to a serious but manageable scientific and policy issue. The greenhouse effect is nothing new; it has been operating ever since the earth formed. Without it, the surface of the globe would be a frigid –20 ℃ (–4 °F), the oceans would have frozen, and no life would have developed.

问答题Even the most uninformed student of climate change could tell you that the solution to global warming is to alleviate global greenhouse gas emissions, and fast. But the problem is that the sheer amount of greenhouse gases we’ve already pumped into the atmosphere has irreversibly bound us to a certain amount of warming over the next several decades. No matter what we do, we’ll have to adapt to it. (1)_______________. Already precipitation patterns seem to be changing, making some drier areas—like the arid American southwest —even drier, and rainy regions even wetter. As warmer temperatures creep northward, so do insects and other pests that are adapted to the heat. The results can be distressing. The tiny mountain pine beetle, which infests pine trees in the Rocky Mountain region, used to be controlled by freezing winters. But as temperatures have warmed over the past decade, the mountain pine beetle’s territory has spread, destroying millions of acres of Canadian pines. (2)_______________Generations of American conservationists have fought to preserve wild- life and to keep nature pristine in the face of a growing population and pollution. To a remarkable extent, they’ve succeeded—almost 16% of the entire landmass of the U.S. is protected, and the Endangered Species Acthas helped save countless animals from extinction. (3)_______________. What good is a wildlife reserve if the protected animals can’t live there, because climate change pushes them out? What difference does it make to defend trees from logging, if global warming will allow a new pest to destroy whole forests? (4)_______________. Last week the Lincoln Institute of Land Policy brought together conservation leaders from around the U.S. to discuss how to cope with warming, trying to work out a new framework for the biggest challenge facing conservation. (5)_______________. So too is the scale required to properly adapt to climate change, which will almost certainly continue for decades into the future. “Climate change will affect agriculture, water resources, forestry, transportation, waste management, energy generation, national security, immigration patterns, fisheries, food security, you name it,” said Lara Hansen. “We need to change the way we allocate resources, plan economies and protect livelihoods.” That means that the way we’ve been carrying out conservation—picking the right land spaces and playing goalie—won’t work anymore, as climate change keeps moving the target. Regardless of what we do, the changes will be coming fast. We need to begin cutting our carbon immediately, but we need to adapt now as well. The world is changing because of us; to save what’s left, we’ll have to change too. [A] But global warming threatens to change all that, by altering the very foundation on which the conservation movement was built. [B] Global warming was already having “profound effects” in the American West, and that the future would bring increased drought, heat waves, rainstorms, extinctions and more. [C] That means climate change isn’t a problem for tomorrow; the effects are happening now. [D] The conference was fruitful, if a bit depressing. What’s clear is that the sheer speed of the changes already taking place due to warming—like the mountain pine beetle infestation—are catching us off guard. [E] Conservationists will have to work even harder, trying to minimize non climate-related threats to land and species. [F] The pine beetle infestation is just one example of global warming’s present danger. It also represents the unique challenges that warming will pose for land conservation managers on the front lines of the battle against it. [G] The answer is to adapt the way we practice wildlife and land conservation to climate change. There’s a term for this—adaptive management.(此文选自Time2008年刊)
