Topic: Global warming.
Specific purpose: To inform my audience about the problem of global warming. Thesis statement: Today I want to share what I’ve learned about global warming and it’s causes.
Attention material: The world stopped getting warmer almost 16 years ago, according to new data released last week. The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures. This means that the plateau or pause in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years. Credibility material: The current cycle of global warming is changing the rhythms of climate that all living things have come to rely upon. What will we do to slow this warming? How will we cope with the changes we've already set into motion? While we struggle to figure it all out, the face of the Earth, as we know it—coasts, forests, farms, and snowcapped mountains—hangs in the balance. Thesis statement: Today I want to share what I’ve learned about global warming and it’s causes. Preview: We need to consider causes, effects and dangers of global warming.
(Transition: Let's begin by understanding more about global warming.)
I. The Earth is warming and human activity is the primary cause. A. U.S. scientists said in the media January 19, 2012, about the influence of mankind on the state of global warming has increased from 18% to 51%. B. The primary way humans cause global warming is by burning fossil fuels. 1. When we drive or fly.
