One of the possible effects of increased carbon dioxide concentration on our planet would be a warmer climate.
<h3>Greenhouse effect</h3>
Carbon dioxide is one of the numerous greenhouse gases that exist in nature. The gases are responsible for the warming of the planet.
Carbon dioxide and other greenhouse gases form a blanket layer in the atmosphere and trap some of the reflected solar radiations from the sun, preventing them from escaping back to space.
