A new report was released this week that outlines the economic costs of global warming. The report, also known as the Stern Report, tries to lay out the costs of both putting an effort into reducing carbon emissions and of doing nothing. The problem is that the numbers in the report don't add up, in many cases understating both the costs of combating climate change and the time it will take to do so.
Also, global warming skeptic Bjorn Lomborg digs deeper into the numbers and shows that certain assumptions made in the 700 page Stern Report are either suspect or appear to made up out of thin air.
In any case the report will give both pro- and anti-global warming supporters plenty to talk about.
