In two or more sentences describe the impact of fossil fuel combustion on the global carbon cycle. in three sentences or less explain why predicting our future oil supply is controversial and involves some uncertainty. state at least one reason for and one reason against both offshore drilling of oil and drilling for oil in the arctic national wildlife refuge. compose a complete paragraph. describe in one complete paragraph how oil and natural gas compare in terms of predicted supply and carbon dioxide emissions.

They increase the amount of greenhouse gases, causing global warming.

Explanation:

The combustion of fossil fuels comes with a number of problems. First, there is an increase in the carbon footprint. This is basically the increase in the amount of atmospheric carbon dioxide due to human activities like burning fossil fuels.  Fossil fuels include natural gas, oil, petroleum, and coal.

These release greenhouse gases, such as methane. These form very reactive radicals that damage the ozone layer resulting in strong and destructive UV rays reaching the earth. In addition, global warming takes place, with an increase in temperature, melting of ice and rising sea levels.

The drilling of oil offshore disturbs the oceanic ecosystem. It pollutes the oceans.

At the same time, it can be an advantage as forests do not have to be destroyed.
