I. Introduction

a.Thesis- Global warming has been credited as the reason for the change in the earth’s temperature; however, the root cause of this is on debate, pinning human activities such as pollution and the emission of greenhouse gases against the earth’s natural climate cycle.

II.Global Warming

a.Causes of global warming

1.Greenhouse Gases and Human pollution (support)

2.Nature cycle (support- earth getting closer to sun, etc.)

b.Global warming’s effects on planet earth (climate change, habitats being destroyed, human life)

III.Argument

a.Main cause of climate change is caused by greenhouse gases and human pollution (show support why)

1.Main greenhouse gases are carbon dioxide and methane

b.The increase in technology and pollution over the years has led to the buildup of more greenhouse gases in the atmosphere, causing the temperature to rise

c.These greenhouse gases absorb heat reflected from the Earth's surface, thus trapping the heat in the atmosphere. Over the last few years, these gases have increased (by emissions) causing them to build up and stop thermal radiation from leaving the Earth, resulting in excess heat (Global Warming)

IV.Human activities are a main factor, posing the question, what can people do to stop global warming (focus on reducing CO2 & methane emissions)

V.Conclusion

a.Reiterate thesis statement and argument

b.Make known that we have to work at lowering pollution and greenhouse gases or else earth’s future will be greatly affected
