I. Read the passage and answer the questions. (2p)

Global warming is primarily a problem of too much carbon dioxide in the atmosphere, which acts as a blanket, trapping heat and warming the planet. Globally, the average surface temperature has increased more than one degree Fahrenheit since the late 1800s. Most of that increase has occurred over just the past three decades. We are overloading our atmosphere with carbon dioxide, which traps heat and steadily drives up the planet’s temperature. Carbon dioxide comes from the fossil fuels we burn for energy, such as coal, natural gas, and oil, and the loss of forests due to deforestation, especially in the tropics. Within the scientific community, there is no debate. Most scientists agree that global warming is happening and that human activity is the primary cause.

Global warming is already having significant and costly effects - and these consequences will only intensify as the planet’s temperature continues to rise. Global warming is accelerating the rate of sea level rise and dramatically increasing coastal flooding risks. Climate change has significant effects for our health, including increased air pollution and a longer and more intense allergy season.

          We must significantly reduce the heat-trapping emissions we are putting into the atmosphere. As individuals, we can help by taking action to reduce our carbon footprint Tropical deforestation accounts for about 10 percent of the world’s heat-trapping emissions. Reducing tropical deforestation can significantly lower global warming emissions and plays an integral role in a long-term solution to global warming. Sometimes it is difficult to achieve meaningful solutions to global warming because misinformation about the truth of global warming misleads and confuses the public and makes it more difficult to carry out effective solutions
