What is the greenhouse effect?
Greenhouse Effect
The greenhouse effect is a natural process that warms the Earth’s surface. It occurs when gases in the atmosphere, called greenhouse gases, trap heat from the sun that would otherwise escape into space. This heat trapping is similar to how a greenhouse works, hence the name “greenhouse effect”.The main greenhouse gases are:
Water vapor
Carbon dioxide
Methane
Nitrous oxide
Ozone
During the day, the sun’s radiation warms the Earth’s surface. At night, the heat radiates back towards space. However, greenhouse gases in the atmosphere absorb some of this infrared radiation, trapping heat near the Earth’s surface and preventing it from escaping into space. Without the greenhouse effect, the Earth would be much colder, with an average surface temperature of around 18°C (0°F). The greenhouse effect makes the planet habitable by keeping temperatures warm enough to support life. However, human activities like burning fossil fuels and deforestation have increased the amount of greenhouse gases in the atmosphere, amplifying the greenhouse effect. This is causing global temperatures to rise, leading to climate change and its associated impacts.
