Greenhouse Gases

Greenhouse gases are gases in the Earth's atmosphere that absorb and emit heat radiation. They form a layer that is essential for regulating Earth's temperature and climate, making it livable for plants, animals and humans. They are used in greenhouses to trap heat and make it easier to grow certain plants in cooler climates. They can also be used to produce energy in devices such as solar panels. Increasing concentrations of greenhouse gases in the atmosphere, due to human activities such as burning fossil fuels, are leading to increasing global temperatures, resulting in climate change.
