By | January 31, 2008

Good morning Chairman Boxer, Senator Inhofe, and members of the Committee. Thank you for the opportunity to speak today. My name is Scott Armstrong. I am a professor at the Wharton School of the University of Pennsylvania. The decision on whether or not to list polar bears under the Endangered Species Act rests heavily on forecasting. I am… Read More »

Witanagemot Justice and Senator Inhofe’s Fancy List

By | January 31, 2008

Anyone interested in the intersection of science and politics has to be watching with some amusement and more than a little dismay at the spectacle of professional immolation that the climate science community has engaged in following the release of Senator James Inhofe’s list of 400+ climate skeptics. The amusement comes from the fact that everyone involved in… Read More »

300 Million US Population in Light of Kyoto, Global Warming and Other Created Hysterias

By | January 22, 2008

FRONT ROYAL, Virginia, October 20, 2006 ( – Opponents of population growth almost always cite environmental concerns, and this week’s media coverage of America hitting 300 million in population was not an exception.

Gore Scientific “Adviser” Says that He has No “Responsibility” for AIT Errors

By | January 15, 2008

In earlier posts, we observed that Al Gore’s An Inconvenient Truth claimed that “Dr Thompson’s thermometer” confirmed Michael Mann’s hockey stick, but, when analyzed, what Gore described as “Dr Thompson’s thermometer” merely proved to be Michael Mann’s hockey stick mis-identified. No wonder it resembled Mann’s hockey stick – or, to use the phrase more common in climate science,… Read More »

Editorial: Global Warming from a Critical Perspective

By | January 9, 2008

This Editorial was inspired by the global warming issue that has appeared over several years in the pages of the APS News and Physics Today (e.g., 1/07, p.72; 8/06, p. 74; 10/04, p. 37; 6/04, p. 60; 6/01, p. 19).

Bearing Up

About the closest most Americans will ever get to a polar bear are those cute, cuddly animated images that smiled at us while dancing around, pitching soft drinks on TV and movie screens this holiday season.

Climate change violates one of Newton’s Laws

By | January 3, 2008

The claim that the science debate over climate change is settled violates the most important of Newton’s Laws. This violation is not of the famous Laws of Motion but of a little known set of derived bylaws, Newton’s Laws of Experts, a major contribution to understanding social dynamics.

A Cold Spell Soon to Replace Global Warming

By | January 3, 2008

Earth is now at the peak of one of its passing warm spells. It started in the 17th century when there was no industrial influence on the climate to speak of and no such thing as the hothouse effect. The current warming is evidently a natural process and utterly independent of hothouse gases.
