Exercise 22

What is the key concept for this section What makes the current atmospheric warming problem urgent Define climate change tipping points and give three examples. Briefly describe the possible effects of a warmer atmosphere on arctic sea ice and land-based ice, permafrost, and sea levels. Define ocean acidification and explain how and why it is occurring. 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.
