Hello. My name is Chris Dakin and Iâ€™m going to be talking about Global Warming today. When people think of global warming, they often picture a hole in the ozone layer, a smoke stack with plumes of smoke pouring from the top, or an earth where the environment is hot and mostly deserted. Fortunately, these ideas about Global Warming will never happen. This is because Global Warming is not something we have to be concerned about. Carbon dioxide is a colorless, odorless, tasteless, non-toxic gas which is essential to all life on earth. All plants require carbon dioxide, or CO2, for survival. The amount of CO2 in the environment has increased over the past 30 years, partly because of carbon ...view middle of the document...
If Gore really means what he writes, he has an opportunity to make a difference by leading by example on the issue of global warming.
A cooperative and productive discussion of global warming must be open and honest regarding the science. Global warming threats ought to be studied and mitigated, and they should not be deliberately exaggerated as a means of building support for a desired political position.
Many of the assertions Gore makes in his movie, ''An Inconvenient Truth,'' have been refuted by science, both before and after he made them. Gore can show sincerity in his plea for scientific honesty by publicly acknowledging where science has rebutted his claims.
For example, Gore claims that Himalayan glaciers are shrinking and global warming is to blame. Yet the September 2006 issue of the American Meteorological Society's Journal of Climate reported, "Glaciers are growing in the Himalayan Mountains, confounding global warming alarmists who recently claimed the glaciers were shrinking and that global warming was to blame."
Gore claims global warming is causing more tornadoes. Yet the United Nations Intergovernmental Panel on Climate Change stated in February that there has been no scientific link established between global warming and tornadoes.
Gore claims global warming is causing more frequent and severe hurricanes. However, hurricane expert Chris Landsea published a study on May 1 documenting that hurricane activity is no higher now than in decades past. Hurricane expert William Gray reported just a few days earlier, on April 27, that the number of major hurricanes making landfall on the U.S. Atlantic coast has declined in the past 40 years. Hurricane scientists reported in the April 18 Geophysical Research Letters that global warming enhances wind shear, which will prevent a significant increase in future hurricane...
