Questions for Climate Change discussion:

 

1a. If climate change occurs as predicted, then much of the polar ice caps will melt. How much is sea level projected to rise as a result of that melting?

 

 b. Now consider the social and political dislocation that will result from that sea level rise. Choose 5 cities that you think are the most important in the world. Use Google, an atlas, or some other source to find the elevation of those cities/ What will the effect be on those cities?

 

c. Let’s concentrate on North America for this part. Find a topographic map of North America. How much of the continental margin will be submerged by the projected sea level rise? Will any large areas disappear? Are any of these areas of significant importance in commerce?

 

d. Now consider the distribution of the human population in North America. If you can find a map that presents population density in North America, how much of the population will be dislocated by that sea level rise?

 

2. There is an extended history of controversy about the “hockey stick” model for earth’s surface temperatures during the last millennium. What are the questions aimed at the model, which suggests most of the temperature increase has occurred in the last century or so?

 

3. In the last few months a completely different type of controversy has arisen. Climate scientists at East Anglia University in England emailed each other. Those emails were hacked, and reveal that those scientists did a number of unethical things: they distributed only censored data that best supported the arguments for climate warming and they, as editors of climate journals, rejected and did not publish (in effect censored) articles critical of climate warming hypotheses. How seriously do you think this weakens arguments that climate is warming, and that the warming is (or should be) a serious concern?
