It contributes to pollution in a variety of ways including: The three main acidic gases responsible for lowering the pH of rainwater are non-metal oxides produced by the burning of fossil fuels like coal, oil and natural gas. In the above experiment, the limewater in the boiling tube changes colour indicating carbon dioxide is produced by combustion of the hydrocarbon fuel. Global warming is having an effect on the worlds climates. In National 4 Chemistry learn more about fuels and how new alternative fuels are being produced. Our main source of fuel is from fossil fuels. It's thought that the build-up of greenhouse gases impacts on global temperature in two ways: The greenhouse effect therefore helps to keep the earth a little warmer than normal and this can lead the climate to change as global warming causes the atmosphere to warm up. Unlike fossil fuels, nuclear fuels do not emit, Nuclear fuels do not emit gasses such as sulphur dioxide which cause. This is called the greenhouse effect, and it keeps our planet warm.
BBC Bitesize Nuclear waste remains radioactive and is hazardous to health for thousands of years, so it must be stored safely. This increase in the Earths temperature is called global warming. Humans burn fossil fuels to power cars and other machines, to generate electricity, and to keep buildings warm. Many scientists believe that the carbon that is part of fossil fuels (coal, oil and natural gas), is one of main causes for the increase in carbon dioxide.
