Global climate change is caused by an increase in the concentration of greenhouse gases in the air, which amplifies the insulating effect of the gases (commonly known as the ‘Greenhouse Effect’). The most abundant greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N20), and fluorinated gases. The […]

When burned for energy, it releases fewer greenhouse gases than coal or oil, but still contributes to global climate change. It is formed underground from the decomposition of plants and animals, and is extracted through drilling or a process known as ‘fracking‘. Learn More Natural […]
