Let us say we are addressing a topic about “Causes of climate change,” our topic sentences will be highlighted.

Introduction

The experienced climate change is a result of global warming caused by human activities (The claim). The rising temperatures have high effects on the whole world since they negatively affect life. While this seems dangerous to all living things, human activities cause the increased global temperatures (the reflection of the claim). Activities such as burning fossil fuels, deforestation, and farming livestock are the activities that threaten normal temperatures (proof of the claim).

Recent studies show that 89% of the global CO2 emissions come from the burning of fossil fuels. These are unavoidable because of the global focus on industrialization. These are brought about by the vehicles, factories, and power stations that emit this gas into the atmosphere. Excessive CO2 limit the amounts of water vapor released into the atmosphere making the temperatures rise significantly. Also, deforestation is a great threat to normal temperatures on the earth. The reason is that trees stores in them CO2.

Greenhouse emissions of toxic gases such as carbon dioxide (CO2), Nitrous Oxide (NOx), Hydrogen gas, among others, lead to the warming planet. This affects the weather by affecting the natural weather patterns. These create the greenhouse effect known to deplete the ozone layer. This exposes the earth to an extreme rise in temperatures. Studies show that livestock farming affects climate change in different ways. The change in land use, feed production, processing affects climate change a great deal. For instance, feed production and manure produce most of the greenhouses gases. These gases include Carbon Dioxide, methane, and nitrous oxides that cause global warming.

Conclusion

The contributor of climate change is global warming. This is due to the concentration of CO2 in the atmosphere. This is majorly caused by human activities such as the burning of fossil fuels and livestock farming. Fossil fuels produce the most emission of CO2 into the atmosphere because it is largely processed to meet the global demands of electricity and heat. Deforestation also contributes to the CO2 in the atmosphere, which also affects the balance of temperatures of the earth.
