Overview of climate change
Climate change is the single greatest problem facing humanity today. Its impacts will be felt by many generations to come, and the future of our entire planet will be determined by how effectively we tackle it. Time is running short, and decisions made over reducing greenhouse gases today will directly affect how much we can limit the impacts of climate change and how much we will be forced to absorb them. However, getting those decisions right requires evidence that is both understandable and based on rigorous science, and carbon accounting has a major role to play in developing this evidence. This chapter gives a brief introduction to the science of climate change, climate change impacts, the greenhouse gases, and some of the key debates in the field.
