Carbon dioxide is primarily responsible for our current concerns about global warming because of its high concentration in the atmosphere and its ability to trap heat close to the Earth's surface. While other greenhouse gases, such as methane and nitrous oxide, are also significant contributors to global warming, carbon dioxide is the most abundant and longest-lasting greenhouse gas emitted by human activities. Water vapor is also a greenhouse gas, but it is not generally considered as contributing to climate change because its concentration in the atmosphere is largely controlled by temperature and not by human activities. Ozone is also a greenhouse gas, but it is mostly concentrated in the stratosphere and not a significant contributor to global warming.
