The gas that is a significant contributor to global warming is carbon dioxide (CO2). Human activities, particularly the burning of fossil fuels and deforestation, have led to increased concentrations of CO2 in the atmosphere. This greenhouse gas traps heat, resulting in a rise in average global temperatures, which contributes to climate change and its associated impacts such as extreme weather, rising sea levels, and habitat disruption. Addressing CO2 emissions is crucial for mitigating the effects of climate change and promoting environmental sustainability.
