This paper describes ‘brightening and dimming phenomena’ in relation to climate change and sunlight and argues that there needs to be more global awareness of these trends. The aim of the article is to focus on world economic prospects, especially the risk and opportunities facing the world food supply due to climate changes. The argument is given that negligence of such problems as brightening and dimming will intensify future challenges reflected in water scarcity, decline in the cultivated arable lands, and the increase in number of refugees. It is argued that adopting risk macroeconomic and environmental policies to face the upcoming economic risks is highly needed and that inattention of such problems will intensify future challenges and devastate development.
