Part 2 Go to http://climate.nasa.gov/interactives/climate-time-machine
7. Click on "sea ice" how does the ice in 1979 compare to the sea ice in 2015?

__________________________________________________________________________________________
8. Click on "Sea level" the sliding bar shows how high sea level will rise if the Greenland ice sheets completely
melt, how many feet will the world's oceans rise if all the ice melts? _____________________ feet.
9. Slide the bar across the bottom while the "southeast United States" is selected. What do you see happening
to the land as you move the bar across simulating the rising of sea levels. What is happening to the coastline
and what will happen to all of the people living there if this really happens?

10. Click on "carbon dioxide" the slide shows the global concentration and distribution of carbon dioxide from
2002-2014 slide the bar from 2002 to 2014. What is happening to the global levels of carbon dioxide?
__________________________________________________________________________________________
11. Knowing that carbon dioxide is a greenhouse gas (meaning it traps heat in the atmosphere) what can you
conclude has happened to the temperature of the atmosphere temperature between 2002 and 2014?
__________________________________________________________________________________________
12. Click on "global temperature" using the slide move the bar from 1884-2015 around what year does the
global temperature start to be 3+ degrees higher? _________________________________________
13. What can you conclude when comparing the global temperature changes from 1884 to 2015?
__________________________________________________________________________________________

14. What things can a higher temperature cause worldwide?
