The primary driver of climate change is the increase in greenhouse gas emissions, primarily carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These gases are released from various human activities, such as burning fossil fuels for energy, deforestation, and industrial processes. The accumulation of greenhouse gases in the atmosphere traps heat, leading to a gradual increase in global temperatures, which contributes to severe weather events, rising sea levels, and habitat loss. Addressing climate change requires global collaboration to reduce emissions, transition to renewable energy sources, and promote sustainable practices.
