Climate change is driven by both natural processes and human activities. Key natural factors include volcanic eruptions, which release large amounts of greenhouse gases and particulates into the atmosphere, and variations in solar radiation. However, the primary cause of recent climate change is human activity. Burning fossil fuels like coal, oil, and natural gas releases significant amounts of carbon dioxide (CO₂) and other greenhouse gases into the atmosphere. Deforestation exacerbates the problem by reducing the number of trees that can absorb CO₂. Industrial processes and agricultural practices also contribute methane and nitrous oxide, potent greenhouse gases. Additionally, human activities such as urbanization and land-use changes alter natural ecosystems and reduce their ability to absorb CO₂, further accelerating global warming.
