Greenhouse gases are gases in the Earth's atmosphere that trap heat, contributing to the greenhouse effect. This effect is essential for maintaining the planet's temperature, but excessive amounts of these gases, such as Carbon Dioxide and Methane, can lead to global warming and climate change. Human activities, including burning fossil fuels and deforestation, have significantly increased the concentration of greenhouse gases. This rise in emissions is a major driver of climate change, impacting ecosystems, weather patterns, and sea levels. Addressing greenhouse gas emissions is crucial for a sustainable future and mitigating climate-related risks.
