Quizplus · Accepted Answer

Carbon dioxide is considered to be the most significant greenhouse gas responsible for global climate change. It stays in the atmosphere for a long time (up to hundreds of years) and is released through human activities like burning fossil fuels, deforestation, and certain industrial processes. Its concentration in the atmosphere has increased significantly since the industrial revolution and is the primary reason for global warming. While other gases like water vapor, nitrous oxide, and methane also contribute to global warming, their concentrations in the atmosphere are much lower compared to carbon dioxide.
