It is ironic that the attempt by two environmental activists to misrepresent my credentials [letters, Feb. 6] coincides with a sustained cold spell in the United States that set a 100-year record. As for full disclosure: My resume clearly states that I consulted for several oil companies on the subject of oil pricing, some 20 years ago, after publishing a monograph on the subject. My connection to oil during the past decade is as a Wesson Fellow at the Hoover Institution; the Wesson money derives from salad oil.
