Why Our Planet is Heating Up

Title: Why Our Planet is Heating Up
Topic:Global warming.
Specific Purpose:To inform my audience about the causes of global warming. Thesis statement:Today I would like to share what I have discovered about the causes of global warming.


Attention material:We’ve all heard stories of polar bears swimming miles into the ocean to find food as their arctic habitat shrinks. We have also witnessed the disastrous effects of last year’s Hurricane Sandy which killed 72 people and caused $50 million dollars’ worth of damage to the East Coast, becoming the 2nd deadliest hurricane in US history. The frightening reality is that these phenomena have a common denominator—global warming—and many leading climatology experts are predicting an increase in the number and intensity of super storms in our near future if the Earth’s warming trend continues.

Credibility material: I like the outdoors a great deal. Every few weeks I try to get out of the city and enjoy a day hike in the mountains, or take an extended walk or jog through the park with my dog. I am sure many of you can relate. We all share a love for our planet and a vested interest in keeping it—and therefore ourselves—healthy. Thesis statement: So, today I would like to share what I have discovered about the causes of global warming so that we might better understand it and therefore prevent further consequences of its effects. Preview:To grasp the reality of global warming, we must consider the increase of CO2 and other caustic emissions, the loss of forestland, and a drastic increase in energy consumption.
