As I was reflecting on the trip, I realized that last week I probably admired some beauty on the New England coastline that will soon disappear. That's right, Global Warming: It's real and if we don't do something about it, oceans will rise and we will lose a lot of our coastal areas. If you think I am crazy and you don't believe that global warming is caused by human activity, you are not alone. According to the chart above from a study by the Pew Research Center, only 49% of the public thinks that the earth is getting warmer because of human activity. However, an overwhelming majority of scientists--84%--agree that the earth is getting warmer because of human activity.
