Is carbon dioxide a major contributor to global warming?

The Earth’s atmosphere is a mixture of many different gases. Several of these gases are known as “greenhouse gases” because they share the characteristic of being excellent absorbers of infra-red radiation.

Such gases absorb radiation emitted by the Earth that would otherwise escape to space and cool the planet. Upon being absorbed, these gases re-emit a fraction of that energy back downward to the surface, keeping the planet warmer than it would otherwise be. In fact, our Earth would have an average temperature of about zero without these greenhouse gases. Continue reading
