1. What is global warming?
Global warming is greenhouse gasses in the atmosphere causing the Earths climate to become hotter.

2. Do you believe in global warming? Briefly explain.
Yes i do believe in global warming because there is evidence of polar ice caps melting and temperature increasing all over the world.

3. Give three pieces of evidence to support your position on number 2.
One piece of evidence is that polar ice caps are melting. Another is that for the past 30-50 years carbon dioxide measurements have increased and so has temperature. My last piece of evidence is that many species of animals are moving to escape the rising temperatures.

4. Despite your response to #2, there are smart people out there that believe the complete opposite of what you believe. Give three pieces of evidence for someone with the opposing viewpoint.
One example of evidence against global warming is that climate computer models are too crude to predict future changes. Another example of evidence is that a modest amount of global warming would be beneficial to the world. One more piece of evidence is that trying to stop emissions would cost too much and it would not even help.
