Carbon dioxide is a colorless and non-flammable gas at normal temperature and pressure. It is the 4th abundant component of dry air. It is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. However, a gradual increase in Carbon dioxide concentrations in the atmosphere is increasing global warming, threatening to disrupt our planet’s climate as average global temperatures gradually rise.
