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)

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.

资料：Earlier this month, presidents Barack Obama of the US and Xi Jinping of China made an important symbolic gesture when they committed their countries, the two largest greenhouse gas emitters, to the Paris climate agreement. It was the clearest signal yet to investors worldwide that they need to think about the implications of global warming for their portfolios.
On Friday afternoon there was an example of what that might mean Mr Obama’s administration issued an order temporarily blocking construction on a section of the Dakota Access oil pipeline. The move was a response to local concerns raised by the Standing Rock Sioux Tribe about potential damage to historic sites and the threats of oil spills. But it is the global issue of climate change that had raised the profile of Dakota Access, making it into a cause celebre for US environmental campaigners. Bill McKibben of 350.org, which played a key role in the successful effort to stop the Keystone XL pipeline from Canada, has suggested that Mr Obama could block Dakota Access permanently, on the grounds that it would exacerbate the threat of climate change.
Last month, the White House’s Council on Environmental Quality issued new guidance for federal agencies, making clear that their decisions should take into account “the potential effects of a proposed action on climate change”, and quantify their consequences for greenhouse gas emissions. Dakota Access is intended to carry crude oil 1,172 miles from North Dakota, a centre of the US shale revolution, to Illinois, en route to refineries around America. The case that it would add to global greenhouse gas emission will be harder to make than for Keystone XL, which would have brought crude from the high-emitting oil sands of western Canada, but the campaigners are certain to try.
If Dakota Access is stopped, it will have a significant impact not just on energy Transfer Partners, the company leading the project, but on all North Dakota oil producers and their customers, who will be forced to use more expensive rail transport.
Climate change is now an unavoidable business issue. In an excellent paper last week, BlackRock, the world’s largest fund manager, set out some of the ways that investors can reduce their exposure to the risks and benefit from the opportunities that it creates. The paper is a landmark in the rising awareness of the issue among mainstream investors. It is one thing when a philanthropic fund with assets of a few hundred million takes a stand on climate issues, quite another when the warnings come from a company with about $4.9tn under management. As BlackRock points out, investors’ personal views on climate science are irrelevant. Enough governments and businesses are convinced by the scientific consensus that the threat is real, and are driving regulatory and technological changes that interested in you.
六If the world is to reduce the risk of catastrophic global warming to acceptable levels, there will have to be a huge reallocation of capital away from fossil fuels and toward low-emission energy sources. That shift has begun, but it needs to go much further. The transition is not straightforward: for as long as oil is the lifeblood of the world’s transport, pipelines will be needed. But when investors and boards make decisions about projects like Dakota Access, they will have to consider their impact on greenhouse gas emissions. The financial consequences of climate change can no longer be ignored.
According to the article, which one of the following statements is false? （ ）A.To reduce the risk of global warming, more should be invested on low-emissions energy sources.
B.Climate change is not only a climate issue, but also a business issue.
C.It’s more difficult to quantify the greenhouse gas emissions on the Dakota Access than Keystone XL.
D.US and China will work together to cope with climate change.

Dakota Access is intended to carry crude oil 1,172 miles from North Dakota, a centre of the US shale revolution, to Illinois, en route to refineries around America. The case that it would add to global greenhouse gas emission will be harder to make than for Keystone XL, which would have brought crude from the high-emitting oil sands of western Canada, but the campaigners are certain to try.
If Dakota Access is stopped, it will have a significant impact not just on energy Transfer Partners, the company leading the project, but on all North Dakota oil producers and their customers, who will be forced to use more expensive rail transport.
Climate change is now an unavoidable business issue. In an excellent paper last week, BlackRock, the world’s largest fund manager, set out some of the ways that investors can reduce their exposure to the risks and benefit from the opportunities that it creates. The paper is a landmark in the rising awareness of the issue among mainstream investors. It is one thing when a philanthropic fund with assets of a few hundred million takes a stand on climate issues, quite another when the warnings come from a company with about $4.9tn under management. As BlackRock points out, investors’ personal views on climate science are irrelevant. Enough governments and businesses are convinced by the scientific consensus that the threat is real, and are driving regulatory and technological changes that interested in you.
六If the world is to reduce the risk of catastrophic global warming to acceptable levels, there will have to be a huge reallocation of capital away from fossil fuels and toward low-emission energy sources. That shift has begun, but it needs to go much further. The transition is not straightforward: for as long as oil is the lifeblood of the world’s transport, pipelines will be needed. But when investors and boards make decisions about projects like Dakota Access, they will have to consider their impact on greenhouse gas emissions. The financial consequences of climate change can no longer be ignored.
What can we learn from Paragragh 5? （ ）A.BlackRock is philanthropic fund that cares about climate change.
B.Investors can take the opportunities brought by climate change.
C.The threat brought by climate change still needs scientific evidence.
D.What investors think of the climate change is very important.

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)
