Question

Quizplus · Accepted Answer

Carbon dioxide is the most responsible for climate change because it is a greenhouse gas that traps heat in the atmosphere and contributes to the warming of the planet. Other gases such as methane and nitrous oxide also contribute to climate change, but carbon dioxide is the most abundant and has the greatest impact. Chlorofluorocarbons (CFCs) are also a potent greenhouse gas, but they are mainly responsible for depleting the ozone layer rather than causing climate change. Hydrogen dioxide does not exist as a gas, as it is simply water (H2O).
