Why are carbon dioxide emissions a concern?
Carbon dioxide is widely believed to contribute to global warming. Carbon dioxide traps heat from the sun and does not allow it to escape back into space from which it came. While a certain quantity of carbon dioxide in the atmosphere is necessary for the maintenance of life on Earth, increased levels may cause the polar ice caps to melt, rising sea levels, more severe storms, and other deleterious environmental impacts. Carbon dioxide is emitted when fossil fuels are burned. Adopting energy-efficient practices in homes can help to prevent global warming.
