1. Other Climate Changes

2. 1. Melting snow mountains 1913 2005 Montana glacier national park

3. Melting Polar ice caps 1979 2001 Arctic Antarctic Greenland 1992 2002

4. 2. Shrinking sea ice cover Arctic Sea Ice Extent: Average for August Arctic Sea Ice Extent: Average for March

5. Rising Sea level Sea level measurements from 23 long tide gauge records in geologically stable environments show a rise of around 20 centimeters (8 inches) per century, or 2 mm/year.

6. 3. Seasonal temperature change. • Global temperature increases aren’t spread evenly around the globe • Heat wave and extreme cold. • Decrease in number of extreme cold days, thereby lengthening the season. • Increases in number of extreme hot days.

7. 4. Weather changes Drought Flood

8. 5. Species Ranges 1. As the temperature across the U.S. has gotten warmer, the purple finch has been spending its winters more than 400 miles farther north than it used to. 2. They found that butterflies moved to sites to the north of their traditional range have thrived in the years since and are spreading from the places they were originally released 3. The range of walnut increases. This species is projected to find suitable mild climate in larger areas of Germany due to global warming 4. Caribou depend on particular plants to nourish them while they nurse their calves. However, these plants are emerging or germinating earlier in the season, in response to warmer temperatures, reaching their peak before calving occurs.
