why is it commonly believed that carbon dioxide is responsible for global warming?\no carbon dioxide levels in the earths atmosphere have been steadily decreasing.\no carbon dioxide has a longer average lifetime in the atmosphere.\no the warming effect associated with carbon dioxide has remained unchanged.\no other greenhouse gases amplify the effect of carbon dioxide.
Answer
Brief Explanations:
Carbon - dioxide is a major greenhouse gas. It has a long - lasting presence in the atmosphere, which allows it to trap heat and contribute to global warming. The other options are incorrect: carbon dioxide levels are increasing, not decreasing; the warming effect can change with changes in concentration; while other greenhouse gases contribute too, the question is about why carbon dioxide is mainly blamed and not about other gases amplifying its effect.
Answer:
Carbon dioxide has a longer average lifetime in the atmosphere.
