Greenhouse Gases
(The Greenhouse Effect)
A greenhouse gas is any gas, such as carbon dioxide, methane, or nitrous oxide that can get stuck in Earth’s atmosphere. Although these gases have always existed, their presence has increased significantly through deforestation, the burning of fossil fuels, and agricultural activities. Given this, the greenhouse effect occurs when the sun heats those gases that have accumulated in the atmosphere. These cause the Earth’s temperature to rise, thus bringing about climate change.
