Hi Mr. Wood, this is my answer to the question " What did you learn from the presentation?" I didn't really get to watch the whole thing I just watched the Fairbanks and the chart part, I'll try to tell you as much as I can. I learned that Fairbanks is in Alaska and it's really cold there. The carbon dioxide level is rising because of the permafrost and it is positive. You saw Mt. McKinley on the airplane. I'm really sorry that I didn't get to see the whole presentation, and that's all I remembered. SORRY!!
