The article discusses how human activities, like burning fossil fuels and deforestation, increase greenhouse gases in the atmosphere, leading to global warming. This warming is causing various impacts, such as rising sea levels, melting ice caps, and more frequent extreme weather events like floods and droughts. These changes affect ecosystems, health, agriculture, and water resources. Greenhouse gases like carbon dioxide and methane trap heat from the sun, creating a natural greenhouse effect that keeps Earth warm. However, human activities have intensified this effect, contributing to climate change. It's important to understand and address these risks to protect our environment and society.
