Lesson 4 Reading Assignment

PrintPrint

In the reading assigned this week, Pacala and Socolow (2004) demonstrate that we can "solve" the climate change problem for the next half century by implementing technologies that we already have today. The catch is that we need to apply these technologies quickly and massively, which requires the nations of the world to agree on energy policies –– without delay –– that might not be in their self-interest.
