13. Conclusion
 My first moment of surprise was learning that the average
temperature has increased by 1.4 degrees Fahrenheit around
the world. After further research I know that temperatures will
only continue to increase.
 It was also new to me that volcanic emissions are a natural
cause to global warming. When I think of global warming I think
of carbon monoxide and solar activity.
 This presentation was my first time using hyperlinks in a power
point so it was interesting learning how to do so.
