What is the Greenhouse Effect?
The greenhouse effect is a natural process that warms the Earth’s surface. When the sun’s energy reaches the Earth, some of it is reflected back to space and the rest is absorbed, warming the planet. The absorbed energy is then re-radiated as infrared radiation.
Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), trap some of this infrared radiation in the atmosphere. This trapped heat keeps the Earth's temperature at a stable level, which is vital for sustaining life. Without the greenhouse effect, our planet would be too cold, making it inhospitable.
However, human activities, particularly the burning of fossil fuels and deforestation, have increased the concentrations of greenhouse gases in the atmosphere. This enhancement of the greenhouse effect leads to global warming and climate change, which can result in severe consequences such as rising sea levels, extreme weather events, and biodiversity loss.
Understanding the greenhouse effect is crucial for addressing climate change. It highlights the importance of reducing greenhouse gas emissions and implementing sustainable practices to protect our environment for future generations.
