"Earth's surface has undergone unprecedented warming over the last century, particularly over the last two decades. " This is what one article from ucsusa.org says is undergoing our relatively young earth. Using words such as unprecedented to really put fear in the reader's mind. Scientist today feel that they have found better then ever the "human fingerprints" all over the global warming issue and it's effects over the last 50 years. The article contains charts that shows the direct correlation between the warming of the earth, warming of the oceans and the atmosphere shifts and thier inks to human activity. The article, written by scientists searching for a way to gain public support on the issues use words and photographs that show global is a pending threat on our future. The language used gives a very threatening feel "...the energy choices we make today greatly influence the climate our children and grandchildren inherit." They need to sell their data for their side of the debate and they are doing it pretty well in this article.
