<p>Grade 10 Science Climate Change</p><p>Is Climate Change Occurring? Looking at the data</p><p>A. Climatographs What can examining climatographs tell us? Using the data on p. 271, construct the two climatographs below:</p><p>1. Study each climatograph. Write a few sentences on each, describing the data, such as monthly data changes and if you think the temperature and precipitation are related.</p><p>2. Compare the two climatographs and describe any differences you observe between them Explain any differences. </p><p>3. Did climate change occur between 1850 and now? </p><p>1 Grade 10 Science Climate Change</p><p>B. Atmospheric Changes p. 310 – 312 1. What are 5 atmospheric changes that may indicate climate change?</p><p>2. Give examples of what has been happening or could happen that illustrate the 5 atmospheric changes. </p><p>3. Look at Figure 8.23 on p. 311. a) From 1950 to 1960, what is the average number of windstorms, floods and temperature extremes per year?</p><p> b) From 1995 to 2005, what is the average number of windstorms, floods and temperature extremes per year?</p><p>4. What can you conclude from the previous data?</p><p>2 Grade 10 Science Climate Change</p><p>C. Hydrospheric Changes p. 312 – 315 1. What are 3 hydrospheric changes that may indicate climate change?</p><p>2. Look at Figure 8.24 on p. 312. Using the map’s scale, estimate the number of square kilometers covered by ice in the summer: a) from 1979 – 2000</p><p> b) in 2005</p><p> c) in 2007</p><p>3. What are some of the ways melting ice affects the Earth?</p><p>4. Look at Figure 8.25 on p. 313. What conclusions can be drawn from this data?</p><p>5. What are some of the ways ocean warming affects the Earth?</p><p>6. How does melting glaciers and sea ice affect the ocean’s currents? What would the consequences of this?</p><p>3 Grade 10 Science Climate Change</p><p>D. Wildlife Changes p. 315 – 317 1. What wildlife evidence exists that climate change is occurring?</p><p>2. How have the Gray jays been affected?</p><p>3. What other range shifts have been observed?</p><p>4. Why are coral reefs threatened?</p><p>5. Which organisms have benefitted from climate change? Why?</p><p>4</p>
