A carbon tax is the most efficient way to reduce omissions, says John Sutter. It's not always the case that pricing externalities is the right approach, he argues. The idea of a carbon tax is asking you to pay for the damage you're causing - and we don't know exactly what it is. We should band all kinds of things but those are politically unattractive," writes Sutter.
Economist Robert Pindyck of MIT talks about his book, Climate Future, with EconTalk host Russ Roberts. Pindyck lays out what we know and do not know about climate change. He argues that because of the nature of greenhouse gases, adaptation must be part of the policy response to climate change.
