Carbon dioxide is a greenhouse gas, meaning that it absorbs heat and releases it slowly over time. Carbon dioxide concentrations are increasing due to the fossil combustibles that society is using to create energy. The constant rise of greenhouse gases in the last 200 years has caused the Earth's energy balance to become unstable, absorbing extra heat and increasing Earth's temperature.
