My understanding, is that if we look at the mixture of factors that are affecting climate change, the biggest contributor will be a gas called carbon dioxide and that is a by-product or its emitted or its released when you burn fossil fuels like oil and coal and gas as the by-product. Greenhouse gases are one of the most important contributors to climate change, so if we can reduce the emission of carbon dioxide that will be one of the most important things we can do and that’s where some of the other sources of energy, like renewable energy from wind and solar energy, can replace our reliance on burning coal and oil, things that we call fossil fuels – Professor Chris Stokes, Durham University.
