Summary: Economic growth requires increasing economic output, which can deplete resources and cause environmental degradation. Problems such as climate change and air/water pollution are examples of this. The question for economists and society is whether the damage to the planet is justified by the benefits of higher incomes. We will begin to study that tradeoff today.

Listen to this podcast. Focus on this question as you listen: How does economic growth affect the environment?
Bjorn Lomborg, President of the Copenhagen Consensus Center, talks about the costs and benefits of attacking climate change with EconTalk host Russ Roberts. Lomborg argues that we should always be aware of tradeoffs and effectiveness when assessing policies to reduce global warming. He advocates for realistic solutions that consider the potential to improve human life in other ways. He is skeptical of the potential to move away from fossil fuels and argues that geo-engineering and adaptation may be the most effective ways to cope with climate change.
And this one. Focus on the same question.
Is climate change the ultimate Black Swan? Martin Weitzman of Harvard University and co-author of Climate Shock talks with EconTalk host Russ Roberts about the risks of climate change. Weitzman argues that climate change is a fat-tailed phenomenon--there is a non-trivial risk of a catastrophe. Though Weitzman concedes that our knowledge of the climate is quite incomplete, he suggests that it is prudent to take serious measures, including possibly geo-engineering, to reduce the accumulation of carbon dioxide in the atmosphere.
