The slow moving Senate debate over climate change offers an opportunity to revisit the fundamentals of climate change. While the physical science about natural and anthropogenic forcings is the place to start, the economics of climate change is highly relevant for the policy debate. In this regard, a perfectly timed literature review in the Spring 2009 The Journal of Economic Perspectives is worth studying.
There have been 13 – count them, 13 – studies published in the peer reviewed literature that have wrestled with the economic implications of a doubling of atmospheric greenhouse gases (GhGs) on a CO2-equivalent basis. Those 13 studies have yielded 14 estimates of what will subsequently happen to global GDP. For those who are curious, 10 of those studies assume a subsequent warming of 2.5 C; two assume that a 1 C warming would follow; and two assume a 3 C warming would follow. …

Covering 11,500 installations and countries with a combined population of around 500 million, the scope of the scheme is truly enormous. Before Americans adopt a cap-and-trade scheme of their own, it is vital that they take a serious look at how things have gone in Europe. I hope that my study, released at the end of last week, can demonstrate some of the huge risks that the United States will face if cap-and-trade advocates get their way.
The first thing to note is that the scheme has cost European consumers a fortune. There was a total bill of €93 ($123) billion between the introduction of the scheme in January 2005 and the end of 2008.…

The reference to me as Stephen Lynch was apparently an editor’s error, but the analogy of oil fields and glasses of water was quite enlightening as to the state of the debate. The three gentlemen comment on the difference between a straw in a glass (a supergiant field) and a puddle of water on the table requires many straws.
In fact, I know of no supergiant fields that have not required many straws, since oil fields are not ‘pockets’ of oil but rather oil that is in rock, rather as water is in a sponge. Drawing all of the fluid from one spot doesn’t mean that all of the oil will flow freely and uniformly to the straw: to the contrary, a given well usually drains a very limited area, and supergiant fields typically have numerous wells, hundreds even thousands, depending on the geology and geography.…
