Question Description
DIRECTIONSfor the question :Read the passage and answer the question based on it.The UN Intergovernmental Panel on Climate Change (IPCC) recently issued a report that said, “Greenhouse gas forcing has very likely (>90 percent) caused most of the observed global warming over the last 50 years.” Many climate doubters and global warming deniers have raised some se­rious questions about the 90 percent figure.Due to these doubts, government representatives were allowed to vote on and revise the IPCC sum­maries, no matter what the data said. As a direct result, China (think coal) and Saudi Arabia (oil) got to veto anything they didnt like. The United States (think do nothing) also had line-by-line veto power.. The deniers call this “politicized Science” and say that the IPCC summaries were just one big, exaggeration, when in fact the reverse is true. They are at most surely understated. It would be like giving a convicted thief a say over the wording of the laws that govern theft. You can bet the final text would go light on thievery. So goes the politicized UN Intergovernmental Panel on Climate Change. While politicized science (an oxymoron if there ever was one) is watered down and conveniently misleading, the real science of global climate change is well understood, and its acceptance in the rigorous world of peer- reviewed science is all but universal. How does global warming work? Well, it can be explained in a simple way.Certain gases carbon dioxide (CO2), nitrogen oxide (N2O), methane,(CH4), and chlorofluorocarbons (CFC) of all kinds--act like blankets thrown across the globe. They trap heat near the earth’s surface. As atmospheric con­centrations of these gases increase, the blanket thickens and global tempera­tures increase. Business, industry, and you and I and everyone else emit about nine billion tons of carbon into the air each year, including the effect, of deforesta­tion. We do it when we start our cars. We do it when we turn on our lights or burn coal to run a generating station. The earth can capture and sequester about 3.7 billion tons of anthropogenic carbon per year. The difference between what we emit mid what the earth can absorb is 9.0 – 3.7 = 5.3 billion tons excess carbon per year. That 5.3 billion tons goes into the atmosphere and stays there, increasing atmospheric concentrations of CO2 by 2 or 3 parts per million each year. Unchecked that CO2 will rise and pass that red line that our best scien­tists believe is out there in the vicinity of 450 pm, which will induce a global average temperature change of two degrees Centigrade (3.8 Fahrenheit). .Also, the world’s oceans and forests are absorbing less of the CO2 released by human activity, adding to the faster rise in atmospheric levels of greenhouse gases. Deforestation is a two-edge sword, as sinks shrinks and CO2 releases from them increase. The ability of ocean to take up carbon decline with warming and acidification and CO2 in water yields carbonic acid, which also threatens any creature that makes a shell. Warming temperatures have prompted earlier springs in the far north and have caused plant species to spread farther into formerly, icy terrain. Meanwhile, summer sea ice in the Artic reached a record low this year. Through melting sea levels, larger expanses of blue Ocean reduce the earth’s albedo (its reflectivity), resulting in greater heat absorption. Also, as forests die and crop¬lands succumb to encroaching deserts, they too are taken of the board as carbon absorbers. As vast regions of tundra and permafrost warm melt they release enormous amount of methane - a greenhouse gas many times, more potent than simple carbon dioxide. Heres the takeaway message: Atmospheric concentrations will continue to increase until the gases we send into the air and the earth’s ability to absorb those gases come into balance.If we have to sum up the situation, we are emitting nearly three times as much greenhouse gases as the earth is able to absorb. It should be obvious from those numbers that we cannot avoid crossing those red lines by planting more trees, because there simply is not enough Land. We must reduce our fossil fuel use to reduce the billions of excess tons of carbon we belch into Air. The crisis-climate change-is very real. That is why we, in the developed nations, need to get our act together on this, to show some real leadership, and to seize insurmountable opportunities. But before we can preach the gospel to the world, we need to put our own house in order. We must turn a deaf ear to the voices assuring us, ‘Everything will be fine, don’t worry! It’s all under control!’ That’s the sort of fatal message that kept card players at the tilting tables in the grand salon of the Titanic. Denial is deadly.Q.What is the author trying to achieve through this passage?a)To identify the limitations with IPCC report by highlighting its politicized nature.b)To propagate the idea that everything associated with changing climate is under control and hence there is no need to worry.c)To stress the idea that a world without fossil fuels is an absolute necessity to combat climate change.d)To highlight the causes and impacts of decreasing carbon sequestration, increasing emissions and mitigation measures required.Correct answer is option 'D'.

That is why we, in the developed nations, need to get our act together on this, to show some real leadership, and to seize insurmountable opportunities. But before we can preach the gospel to the world, we need to put our own house in order. We must turn a deaf ear to the voices assuring us, ‘Everything will be fine, don’t worry! It’s all under control!’ That’s the sort of fatal message that kept card players at the tilting tables in the grand salon of the Titanic. Denial is deadly.Q.What is the author trying to achieve through this passage?a)To identify the limitations with IPCC report by highlighting its politicized nature.b)To propagate the idea that everything associated with changing climate is under control and hence there is no need to worry.c)To stress the idea that a world without fossil fuels is an absolute necessity to combat climate change.d)To highlight the causes and impacts of decreasing carbon sequestration, increasing emissions and mitigation measures required.Correct answer is option 'D'. Can you explain this answer? has been provided alongside types of DIRECTIONSfor the question :Read the passage and answer the question based on it.The UN Intergovernmental Panel on Climate Change (IPCC) recently issued a report that said, “Greenhouse gas forcing has very likely (>90 percent) caused most of the observed global warming over the last 50 years.” Many climate doubters and global warming deniers have raised some se­rious questions about the 90 percent figure.Due to these doubts, government representatives were allowed to vote on and revise the IPCC sum­maries, no matter what the data said. As a direct result, China (think coal) and Saudi Arabia (oil) got to veto anything they didnt like. The United States (think do nothing) also had line-by-line veto power.. The deniers call this “politicized Science” and say that the IPCC summaries were just one big, exaggeration, when in fact the reverse is true. They are at most surely understated. It would be like giving a convicted thief a say over the wording of the laws that govern theft. You can bet the final text would go light on thievery. So goes the politicized UN Intergovernmental Panel on Climate Change. While politicized science (an oxymoron if there ever was one) is watered down and conveniently misleading, the real science of global climate change is well understood, and its acceptance in the rigorous world of peer- reviewed science is all but universal. How does global warming work? Well, it can be explained in a simple way.Certain gases carbon dioxide (CO2), nitrogen oxide (N2O), methane,(CH4), and chlorofluorocarbons (CFC) of all kinds--act like blankets thrown across the globe. They trap heat near the earth’s surface. As atmospheric con­centrations of these gases increase, the blanket thickens and global tempera­tures increase. Business, industry, and you and I and everyone else emit about nine billion tons of carbon into the air each year, including the effect, of deforesta­tion. We do it when we start our cars. We do it when we turn on our lights or burn coal to run a generating station. The earth can capture and sequester about 3.7 billion tons of anthropogenic carbon per year. The difference between what we emit mid what the earth can absorb is 9.0 – 3.7 = 5.3 billion tons excess carbon per year. That 5.3 billion tons goes into the atmosphere and stays there, increasing atmospheric concentrations of CO2 by 2 or 3 parts per million each year. Unchecked that CO2 will rise and pass that red line that our best scien­tists believe is out there in the vicinity of 450 pm, which will induce a global average temperature change of two degrees Centigrade (3.8 Fahrenheit). .Also, the world’s oceans and forests are absorbing less of the CO2 released by human activity, adding to the faster rise in atmospheric levels of greenhouse gases. Deforestation is a two-edge sword, as sinks shrinks and CO2 releases from them increase. The ability of ocean to take up carbon decline with warming and acidification and CO2 in water yields carbonic acid, which also threatens any creature that makes a shell. Warming temperatures have prompted earlier springs in the far north and have caused plant species to spread farther into formerly, icy terrain. Meanwhile, summer sea ice in the Artic reached a record low this year. Through melting sea levels, larger expanses of blue Ocean reduce the earth’s albedo (its reflectivity), resulting in greater heat absorption. Also, as forests die and crop¬lands succumb to encroaching deserts, they too are taken of the board as carbon absorbers. As vast regions of tundra and permafrost warm melt they release enormous amount of methane - a greenhouse gas many times, more potent than simple carbon dioxide. Heres the takeaway message: Atmospheric concentrations will continue to increase until the gases we send into the air and the earth’s ability to absorb those gases come into balance.If we have to sum up the situation, we are emitting nearly three times as much greenhouse gases as the earth is able to absorb. It should be obvious from those numbers that we cannot avoid crossing those red lines by planting more trees, because there simply is not enough Land. We must reduce our fossil fuel use to reduce the billions of excess tons of carbon we belch into Air. The crisis-climate change-is very real.
