2 Click and drag the word to fit the proper description. Word Ice Off Dates Ice Core Samples Description 1.Scientist can check the gases in the bubbles and provide a good estimate of the temperature at that time. 2.Scientist can study how humans have lived in the past to help determine what the climate was like. 3.Scientist can use pollen within the various layers to make inferences of what the climate may have been like. 4.Scientist can look at the width of rings to infer what the climate may have been like during the formation of the ring. 5.Using freezing and thawing dates of lakes to help determine what the climate was like. 6.Scientist can use the remains of animals that died a long time ago to help determine the climate. Sediment Cores Archaeological Records Fossil Tree Rings

3 What does the above graph show has happened to the yearly temperature and climate over the past 150 years? Explain what information you used to develop your answer to question above.

4 Matching: Click and Drag Climate Paleobotany Water Vapor Carbon Dioxide Methane Greenhouse Effect The most important greenhouse gas that we have no direct control of. This is also called marsh gas and found in cow burps and toots. The study of vegetation to determine past climates. Weather over a long period of time The most important greenhouse gas that we have some control over. A natural phenomenon that was established long before humans existed.

5 True or False? Click and Drag True False Climate naturally cycles through high and low temperatures. Increased Nitrogen Oxide levels can lead to global warming. Scientists believe that global warming is mostly due to humans. Melting of the North polar ice would have a greater impact on sea level rise than the melting of the South polar ice. Global warming will have no affect on Wisconsin.

6 What does the above graph show has happened to the yearly temperature and climate over the past 150 years? The above graph shows the temperature fluctuates from year to year, however, the climate has gotten warmer over the last 150 years. Explain what information you used to develop your answer to question above. The above graph shows, that in general, the duration of ice on Lake Monona has decreased over the last 150 years. This evidence would indicate that the climate has gotten warmer.

9 Click and drag the word to fit the proper description. Word Description 1. Describes long term weather patterns. 2. Includes natural variability and climate patterns. 3. This may be due primarily to human activities adding pollution to the atmosphere. 4. A good, natural phenomenon that keeps our planet warming enough for us the live here. Climate Greenhouse Effect Global Warming Climate Change

10 Circle the correct answer (s). Which one does deforestation not contribute to? a. erosion b.global warming c. ozone depletion Climate may be influenced by. a. humans b. mountains c.large bodies of water d. all of them When gas, oil and coal are burned, is released into the atmosphere. a. water vapor b. carbon dioxide c. ozone d. oxygen The Earth s atmosphere acts much like a. a. greenhouse b. conductor c. cooler

11 Circle the correct answer (s). Possible affect (s) of global warming include. a) increased chances of mosquito born diseases b) a change in weather patterns c) lower crop yields in Wisconsin d) all of these The official warmest years on record for the United States were and. a b c d If all greenhouse gases were removed from the atmosphere, the average temperature of Earth would drop approximately degrees Fahrenheit. a. 10 b. 25 c. 45 d. 60 Scientist can learn about past climates by studying. a. fossils b. ice cores c. pollen d. all of these

12 Climate is a complex system that ties together what three pieces? Atmosphere, Ocean and Land The official warmest years on record for the world were and and 2005

13 True False If all greenhouse gases were removed from the atmosphere, the average temperature of Earth would drop approximately 60 degrees Fahrenheit. One extreme summer in the United States would be a strong indicator of climate change. The reflection of the sun s radiation back into space by the Earth s atmosphere and snow is called the Albedo Effect. Solar energy reaching the Earth must equal the energy leaving the planet otherwise the oceans would eventually boil away or freeze solid.

15 Matching: Click and Drag Carbon Dioxide Nitrous Oxide Chlorofluorocarbons Water Vapor Methane CFC s CH 4 H 2 O CO 2 N 2 O Circle the three greenhouse gases that we currently have the most control over.

16 True or False? Click and Drag True False Some greenhouse gases are here naturally while others are from human activities. Water vapor is a heat trapper in the atmosphere. Increased nitrogen oxide levels can lead to global warming. Water vapor is the least important greenhouse gas. CFC s are human-made heat trappers in the atmosphere. Burning fossil fuels releases CO 2 into the atmosphere.

17 True or False? Click and Drag True False Some greenhouse gases are here naturally while others are from human activities. Warm ocean water occupies a larger volume than cooler ocean water. The greenhouse effect is good for humans and other life on Earth. Water vapor is the least important greenhouse gas. CFC s are heat trappers in the atmosphere. Burning fossil fuels releases CO 2 into the atmosphere.

18 sources sinks methane CO2 water vapor The most important greenhouse gas we have some control over. Also called marsh gas and found in cow burps. The most important greenhouse gas we have no direct control over. Release elements into the atmosphere. Stores elements that are released into the atmosphere.

19 Explain the two ways that deforestation can impact the levels of greenhouse gases in our atmosphere. Removing live trees eliminates their ability to absorb (store) carbon dioxide (CO2) from the atmosphere. Burning the cut trees releases carbon dioxide (CO2) back into the atmosphere.

Includes natural variability and climate patterns. This may be due primarily to human activities adding pollution to the atmosphere. This is good for life on Earth. It helps keep us ~60 0 F warmer than if it did not occur. Some of these occur naturally and artificially in our atmosphere. These are all possible contributors to global warming. (They do not need to be in order.) These are all possible contributors to climate change. (They do not need to be in order.)

22 True or False? Click and Drag True False Warm ocean water occupies a larger volume than cooler ocean water. The greenhouse effect is good for humans and other life on Earth. Melting of the North polar ice would have a greater impact on sea level rise than the melting of the South polar ice. Global warming will have no affect on Wisconsin.

23 True or False? Click and Drag True False All scientists believe that global warming is entirely due to human activity. Ozone depletion is the main cause of global warming. The U.S. makes up approximately 5 percent of the worlds population but contributes approximately 25 percent of the greenhouse gases. The burning of coal in order to create electricity is a major contributor to greenhouse gases.

24 True or False? Click and Drag True False Burning natural gas, oil and coal release carbon dioxide into the atmosphere. Driving hybrid cars would increase the amount of carbon dioxide being released into the atmosphere.

25 According to this graph, is there a relationship between CO2 emissions and temperature change? Explain your answer. Explain two possible ways to reduce your carbon footprint?

26 According to this graph, is there a relationship between CO2 emissions and temperature change? Explain your answer. Yes, as the amount of CO2 has increased, so has the temperature. Explain two possible ways to reduce your carbon footprint? AWV *These are listed not explained.* Drive less, Keep vehicles tuned properly Walk/ride bike more, Use snow blower less/shovel more Reduce electrical use, Plant trees/recycle
