Abstract

This chapter discusses how the human food systems contributes to climate change and some solutions to reduce its impact. The discussion starts with an explanation of the climate processes, reviewing the concepts of the greenhouse effect, the carbon cycle, and the global warming potential. Then it looks at how humans are impacting these processes, resulting in anthropogenic climate change. The chapter explains that the presence of extra greenhouse gases in the atmosphere results in the trapping of more energy (in the form of heat) in the Earth's different systems, predominantly the oceans and the atmosphere. This, in turn, results in changes in our climate, including more extreme weather events such as droughts, floods, hurricanes, and fires. Furthermore, the chapter presents case studies to show how complicated some food choices are. Lastly, it tackles how climate change will impact food systems as the environment changes.
