1.5 Fossil fuels, greenhouse gases and climate change
Society’s current use of fossil fuels has many adverse consequences. Here we’ll concentrate on their emissions of greenhouse gases that contribute to global climate change.

So what is the chain of events that cause climate change on a global level?
