Explain how atmospheric warming, global drought, extreme weather, and an intensified water cycle are related. What are the possible effects of climate disruption on biodiversity, food production, and human health and economies Pick three of these effects and describe how each can become part of a positive feedback loop leading to increased climate disruption. Summarize the science community's discussion of whether or not the IPCC scientists were too conservative in their projections.
