USA Today Magazine Articles 2001-2023

This book gathers together the articles I published in USA Today Magazine. They cover a large variety of topics and the book contains a commentary, sometimes giving history and technical details that could not be included at the time.

IRRADIANCE VARIATIONS DUE TO ORBITAL AND SOLAR INERTIAL MOTION: THE EFFECT ON EARTH’S SURFACE TEMPERATURE

Variation in total solar irradiance is thought to have little effect on the Earth’s surface temperature because of the thermal time constant—the characteristic response time of the Earth’s global surface temperature to changes in forcing. This time constant is large enough to smooth annual variations but not necessarily variations having a longer period such as those due to solar inertial motion; the magnitude of these surface temperature variations is estimated.

Interglacials, Milankovitch Cycles, and Carbon Dioxide

The existing understanding of interglacial periods is that they are initiated by Milankovitch cycles enhanced by rising atmospheric carbon dioxide concentrations.  During interglacials, global temperature is also believed to be primarily controlled by carbon dioxide concentrations, modulated by internal processes such as the Pacific Decadal Oscillation and the North Atlantic Oscillation.  Recent Work challenges the fundamental bases of these conceptions.
