Global Warming: The Potential Impact

There was a one-degree Fahrenheit increase in global temperatures during the 20th century. The signs of change from this rise can be seen across the globe. In Alaska warmer winters allow bark beetle eggs to survive. The bark beetles are destroying the spruce trees. In Greenland fisherman cannot pull their sleds over slushy ice fields. There are also examples such as hurricane Katrina which devastated New Orleans. The global temperature is predicted to continue rising due to the build up of carbon dioxide in the atmosphere from burning gases. According to professor Lonnie Thompson from Ohio State University, there is a great cause for concern.
