Sera gazları 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 can lead to global warming. Common greenhouse gases include karbondioksit, metan, and azot oksit. Human activities, such as burning fossil fuels and deforestation, have significantly increased the concentration of these gases. This rise in sera gazları is linked to climate change, which can cause extreme weather, rising sea levels, and disruptions to ecosystems. Reducing emissions is crucial for a sustainable future.
