Answer Key

1. C

Water vapor creates what scientists call a 'positive feedback loop' in the atmosphere making any temperature changes larger than they would be otherwise (IPCC)

2. FALSE

Between the 1960s and the present day the same solar measurements have shown that the energy from the sun is now decreasing.

Figure 1: Global temperature (red, NASA GISS ) and Total solar irradiance (blue, 1880 to 1978 from Solanki , 1979 to 2009 from PMOD ).

 

3. FALSE

Changes are due to natural factors as well as human interaction of consumption, energy use and resource extraction (National Geographic)

 

4. C

China passed the United States in Global Warming with the increase in the industrial sector (National Geographic)

 

5. A

Carl Sagan studies over Venus's atmosphere led to his concern over planet Earth (National Geographic)

 

6. B

The World Heath Organization contributes 150,000 deaths per year on the effects of global warming include extreme weather, drought, heat waves, decreased food production, and the increase of the spread of disease. (The World Heath Organization)

 

7. D

100 years (National Geographic) which means that the effects would be felt decades after.

 

8. TRUE

Ice-covered surfaces reflect more solar energy than ice-free surfaces and therefore have a global cooling effect, as ice covered surfaces are reduced; global warming will accelerate because more heat will be absorbed. (National Geographic)

9. B.

A 2006 study revealed that because airplane exhaust contrails reflect little to no sunlight during nighttime and wintertime flights, they are less able to compensate for the climate warming gases they contain. (National Geographic)

 

10. A

Sometimes this is the case. Hybrid cars combine an internal combustion engine with a battery system to improve efficiency. In many cars this translates to improved fuel economy, but some hybrids use those savings for added power.

 

11. D

All the above, global warming interconnects all of these industries.

 

12. C

6 hours (Get Caught Recycling Website www.ksewaste.org)

 

13. E.

All of the above (Get Caught Recycling Website www.ksewaste.org)

14.B

Dirt is not a main component in manufacturing glass (www.epa.org)

 

15.C

It takes the average aluminum can 80-100 years to decompose (www.epa.org)

 

16. C

Recycling two bottles saves enough energy to boil water for five cups of tea. (www.epa.org)

 

17. Which action does not save energy in your home? D.

Leaving the lights on only in the rooms you are moving inbetween (www.epa.org)

 

18. B (37%)

In the 10,000 years before the Industrial Revolution in 1751, carbon dioxide levels rose less than 1%. From 1751-2003, humans added 466 billion tons of carbon to the atmosphere in the form of carbon dioxide. Eighty-five percent of all human-produced carbon dioxide comes from burning coal, natural gas, oil and gasoline (http://www.climate.nasa.gov)

 

19. A (Deforestation)

Forest clearing produces about a fifth of current carbon dioxide emissions. Cows that produce massive amounts of methane (also a potent greenhouse gas) are a cause for concern in countries with large cattle industries. (http://www.climate.nasa.gov)

 

20. C.

Forty to 50 percent of the carbon dioxide stays in the air, and 30 percent is dissolved in the oceans. Scientists are not sure about the rest. They believe it is absorbed by forests, soil and crops. (http://www.climate.nasa.gov)

 

21. D all of the above

The amount of carbon in the oceans, land and air is naturally very finely tuned, but human activity is upsetting that balance, with effects all over the globe. NASA ? s Soil Moisture Active Passive (SMAP) mission, to be launched in 2010-2013, will use soil moisture measurements to improve our understanding of the water, energy and carbon cycles. (http://www.climate.nasa.gov)

 

 

22. B

Half of this 20-ton so-called "carbon footprint" comes from transportation (cars, trucks, buses, aircraft). In contrast, the average European produces about 14 tons per year, and the average Indian about 1 ton per year. For a sustainable way of life, each person on the planet should produce no more than 2 tons of carbon dioxide per year (http://www.climate.nasa.gov)

 

23. D

Shutting down fossil-fuel plants and moving to clean, renewable energy sources such as the sun and wind would have the biggest impact. Coal-based plants are the least carbon-efficient power stations. (http://www.climate.nasa.gov)

 

24. B.
Even if we stopped all carbon emissions right now, the hundreds of billions of tons of carbon dioxide that have been pumped into the atmosphere and absorbed by the oceans since the Industrial Revolution would continue to warm the planet. For how long? No-one knows for sure, but estimates range from hundreds of years to thousands of years into the future. (http://www.climate.nasa.gov)

 

25. D

Recycling the print run of a single Sunday issue of the New York Times would spare 75,000 trees. (www.greenforall.org)

 

26. In 2007, cell phones were recycled at a rate of approximately 10 percent. (EPA)

 

27. Consumer electronics make up almost 2 percent of the municipal solid waste stream. Though it is a small percentage, the quantity is steadily increasing. (EPA)

 

28. Almost all of the materials used to manufacture a cell phone can be recovered to make new products. Metals, plastics, batteries and the packaging materials can be recycled and turned into new products. (EPA)

 

29. False-Carbon dioxide in the atmosphere is the leading cause of global climate change (www.greenforall.org)

 

•  For the three R's, redirect is not within the Reduce, Reuse, and Recycle! However it is important that we learn to REDIRECT our way of thinking towards a cleaner, greener planet!
