I can’t help bu get excited when major, mainstream business publications have interesting storied related to environmental matters and in particular, climate change. The Financial Times (link via WBCSD) has a great piece on a good overview of the problems encountered in trying to justify costs in the short term that may or may not offset long term disasters.
It has taken some time for the economics of climate change to enter the mainstream. While scientific knowledge in this area has leapt ahead, economic advances have been much slower. You do not have to look far for the reasons. Most economics theory is designed to cope with issues that are relatively short term or national. Even international economics is ill-equipped to deal with trans-boundary issues.
