Watch this video on the history of earths climate and answer these questions:
List three things that may have had a major effect on the earths climate and what change they had on the climate.
Are we currently in an ice house climate or a green house climate? What would be the danger if we switched from one to another?
How do you think we figured out what the climate was like long before their were humans?

With a partner, open up this sheet of ice core data. This is a collection of measurements taken from an ice core extracted in Vostok, Antarctica. In it you have three columns: the depth of the ice (in meters), the ratio of different isotopes in the ice, and the age of the ice (in thousands of years). As the ice gets deeper, we're working with older and older ice.
Make a copy of the data so you can manipulate it (right-click on the Master Data-set tab and select copy to new spreadsheet).
We want to plot temperature over time. The age of our ice already gives us a good sense of time and we can figure out what the temperature was like when the ice formed based off of the different isotopes in the ice. The formula we will use is Temp = -55.5 + (Isotope+440)/6
In the next column of the spreadsheet enter the above formula for temperature, starting from the equal sign. Instead of writing isotope, click on the first data point in the isotope column. After you finish entering the equation, google sheets should do the calculation for you.
Grab the bottom corner of the calculation you just completed and drag it all the way down to the bottom of your data. Google Sheets should calculate all of your temperature data!
Highlight the age of ice and newly created temperature columns and click insert -> chart. Be sure to label your axis's.
You should have a nice graph of the temperature data for the last 150 thousand years. Check that this data is accurate by comparing recent temperatures on your graph to the current average temperature in Vostok, Antarctica.
Email your data sheet (put both names in the title) with graph to ksultzer@psd267.org
Human society appeared around 12000 years ago. Has human society experienced any massive temperature changes according to this data?
When was the last maximum temperature?
How can we use this data to study climate change?

Geography and Climate
At your tables, create a poster to describe one of the following geographic effects on weather (each is a link to an article you can used to get started):
Your poster should include a diagram and answer the following questions:
Where is your effect found?
How does the geography create this effect?
How does the weather change due to this effect?
