Greenhouse gases

Greenhouse gases are atmospheric gases that trap heat in the Earth’s atmosphere, creating the natural greenhouse effect that maintains temperatures suitable for life. The most common greenhouse gases include carbon dioxide (CO2), methane (CH2), nitrous oxide (N2O), and fluorinated gases. These gases allow sunlight to enter the atmosphere freely but absorb and re-emit heat energy, preventing it from escaping into space. While this process is essential for life on Earth, human activities such as burning fossil fuels, deforestation, and industrial processes have greatly increased the concentration of greenhouse gases, intensifying global warming.

This rise in greenhouse gases is a primary driver of climate change, leading to higher global temperatures, melting ice caps, sea-level rise, and more extreme weather events like hurricanes and droughts. Carbon dioxide, primarily generated from the combustion of coal, oil, and natural gas, is the most prevalent human-made greenhouse gas. Methane, released from agriculture, landfills, and fossil fuel extraction, is far more potent in trapping heat but exists in smaller amounts. To reduce greenhouse gas emissions, the world is shifting towards renewable energy sources, improving energy efficiency, and protecting natural carbon sinks such as forests. International agreements like the Paris Agreement aim to limit global temperature rise and encourage countries to commit to reducing emissions to protect the planet.
