Extreme weather conditions, such as, very high ambient temperature (El Nino), torrential rainfall bordering on flooding (La Nina), excessive drought, tsunami, hurricane, all of which, will have a very profound effect on global farming, which will be, invariably, very deleterious to production. This, in turn, will adversely affect global food security. Some of these are discussed in the book of this author “Combating Global Warming: The Role of Crop Wild Relatives for Food Security” (Nair in Combating global warming the role of crop wild relatives for food security. Springer Nature Switzerland AG, 2019b). Emission of greenhouse gases (GHGs) is an additional and very important source of climate change. Climate change will, additionally, adversely affect food prices, especially for the principal staples like, wheat, rice, corn and soybean (IFRI in Climate change: impact on agriculture and costs of adaptation. International Food Policy Research Institute, Washington, USA, 2009).
