What Are Greenhouse Gases
What are Greenhouse Gases?
These are the gases that make up our atmosphere:
Carbon Dioxide 89%
Methane 7%
Nitrous Oxide 3%
Halocarbons 1%
What is the Greenhouse Effect?
The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in, but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere.
What human activities produce Greenhouse Gases?
By burning fossil fuels such as coal, oil and gas, Carbon Dioxide is released into the atmosphere. Deforestation also releases Carbon Dioxide.
Farming in rice paddy fields and cattle farming produces Methane.
Nitrous Oxide is produced by jet craft, car and lorry engines. It is also released through fertilisers and sewage farms.
Halocarbons are used in industry solvents and cooling equipment.
How has the growth of greenhouse gases in the atmosphere changed over time?
Levels of Greenhouse Gases have increased by about 25 percent since industrialization began 150 years ago. During the past 20 years, over three quarters of Carbon Dioxide emissions were from burning fossil fuels.
Which places in the world produce the most greenhouse gases?
North America and Australia produce the most amount of carbon dioxide because people are wealthier so are more likely to afford luxuries such as having more than one car per household.
What are the projections for the future levels of greenhouse gases?
If we continue to emit greenhouse gases or increase how much we are currently emitting, it would cause further warming and increase changes in the global climate system which are likely to be bigger than those observed during the 20th century.
