In any event, it has never been true that we ignore mainstream science; and anyone who reads AEI publications closely can see that we are not 'skeptics' about warming. It is possible to accept the general consensus about the existence of global warming while having valid questions about the extent of warming, the consequences of warming, and the appropriate responses.

As with Three Mile Island, the hysteria of the media and the political class over the Deepwater spill is likely to lead to increased risk and adverse environmental tradeoffs.
