Global warming is a concern to all people throughout the world (I). And it should be a concern. Not only are people affected by global warming, but there is new evidence that shows people have caused most of the warming changes over recent years. The earth and the people who live on it need greenhouse gas (II). Some, but not all, of greenhouse gas occurs naturally in the atmosphere. As the sun heats the earth responds by returning or radiating some of the sun's energy back into space (III). As the energy is returned, greenhouse gases in the atmosphere- water vapor, carbon dioxide, nitrous oxide, and methane-retain some of the heat in the atmosphere and, as a result, make our earth have a warmer temperature than it would without the absorption (IV).

When greenhouse gas increases, the ability of the gas to trap heat increases and the earth surface temperature becomes warmer. Our earth's surface temperature has been increasing over the past century, especially in the last couple of decades. Many attribute this change to often the amount of carbon dioxide that is emitted into the atmosphere. Changes in emissions began to occur when the Industrial Revolution began in America. America is known as a fossil fuel country because of its use of that kind of fuel in heating homes, powering vehicles, and maintaining factories. Oil, coal, and natural gas are all considered fossil fuels and when these fuels are burned the carbon dioxide they emit is released into the air. The same is true when wood is burned. As carbon dioxide is trapped in the atmosphere, changes in temperature occur.

The causes of something are one matter, but effects are another. When the gasses are absorbed in the atmosphere, climate changes occur. Temperatures rise, evaporation increases, and precipitation also increases to an upward spiral. Sometimes the soil moisture declines and sometimes rainstorms become intense and sea levels rise. What has been observed is the melting of glaciers and decreased amounts of snow-fall in the colder regions of the earth.

Projecting actual changes and the effects of those changes over the next several centuries cannot be accomplished with exactness. Not only will the overall effects be difficult to predict, the real problem comes in predicting the effects on regions and specific localities. For example, the scientists know that if global warming makes the ocean temperatures warmer then the result can be hurricanes of more intensity and frequency. The causes of global warming are known but the exact results and the degrees of the results aren't. Uncertainty as to the gravity and extent of global warming will continue until some certainty is extracted from factual, current, and objective data.

Although uncertainty is a serious concern, there are things people can do. If there is a "no ozone" day in your community, try to adhere to the guidelines set forth by government officials. Don't burn leaves and don't drive unless it is necessary. Carpooling is good not only on "no ozone" days, but all the time. Don't continue to send unnecessary items to the landfills. Recycle. And plant trees- for shade and cooling- as well as for decorative purposes. A better environment can help everyone - now and in the future.

Question 10. Which of the following best summarises paragraph 4?

A. Although the underlying causes of global warming are well-established, the specific details offuture climate change, including regional impacts, remain elusive, necessitating continued research and monitoring.

B. While the causes of global warming are understood, predicting the exact effects on specific regions remains uncertain, hindering precise projections of future climate change.

C. The scientific community acknowledges the potential for severe weather events linked to global warming, but the precise consequences for individual regions and localities are difficult to forecast with certainty.

D. The potential impacts of global warming, such as increased hurricane intensity, are known, but the exact magnitude and timing of these effects remain unclear due to the complex nature of climate systems.

Question 11. The word specific in paragraph 4 is OPPOSITE in meaning to________

        A. general        B. limited        C. particular        D. definite

Question 12. Which of the following is TRUE about most of the warming changes caused by man?

A. Man can regulate the amount of heat absorption in the atmosphere through the use of solar devices.

B. The quality and quantity of fossil fuel used by man has varying effects on the atmosphere and the interplay of the greenhouse gasses within the atmosphere.

C. Man can regulate the amount of emissions of greenhouse gasses by establishing "no ozone" days if actually interested in reducing the problem.

D. Man can control the amount of greenhouse gasses required to radiate the sun's energy.

Question 13. The statement which best summarizes why global warming is a concern to all nations is________.

A. Expensive research projects can never eliminate the problem but at most can only help to alleviate it.

B. When people are careless with fuel emissions, entire countries and future generations will suffer.

C. Only expensive scientific research can eliminate the problem and poor nations are unable to fund such research efforts.

D. The future impact can only be predicted with uncertainty while present consequences of global

Question 14. Which of the following can be inferred from the passage?

A. Global warming is caused only by human activities, particularly the burning of fossil fuels.

B. Greenhouse gases, such as carbon dioxide, trap heat in the atmosphere, leading to an decrease in global temperatures.

C. Individuals can take steps to reduce their carbon footprint and mitigate the effects of climatechange.

D. The effects of global warming are the same and predictable, but may include rising sea levels, more extreme weather events, and changes in agricultural patterns.

Question 15. The sentence which best summarizes the passage is_________.

A. Global warming exists and its negative future effects, while unknown and indeterminable, can partially be eliminated by humans who are presently causing an increase in the warming trend.

B. Global warming is a concern to all people because it impacts the subsurface of the earth by releasing dangerous gases into the lowers of the earth through mining and reforestation and generates heat while limiting oxygenation of the areas.

C. Global warming is a worldwide problem which can be resolved by effective atmospheric control by nation with the financial means to do so.

D. Global warming is a concern to all people because it affects the earth's surface by warming it to temperatures greater than necessary while failing to absorb the harmful gases.
