Hugh W. Ellsaesser

Credentials

• Hugh Ellsaesser holds a Ph.D. in Meteorology and is CEO of HWE Atmospheric Consultant. [3]

Background

A meteorologist by training, Ellsaesser is a retired "guest scientist" at the Lawrence Livermore National Laboratory, and a widely-quoted global warming skeptic.

Stance on Climate Change

"... I am one of the strong supporters of the proposition that the available records indicate climate warming over the past century or so. It's just that I don't believe the observed warming is due to an increase in greenhouse gases." [4]

Key Quotes

"In considering the question of human activity and climate change it is essential to distinguish between global warming, which is a progressive increase in the annual mean global temperature, and human-activity-induced greenhouse warming, as may, for example, be caused by the release of greenhouse gases into the atmosphere as a result of fossil fuel combustion or deforestation." [3]

Key Deeds

November 1996

Ellsaesser brought into question the validity of government action on ozone depletion and reducing the use of CFC’s. In a Nov. ’96 article he states: "The public has been misled to an even great extent in that the possible beneficial consequences of increased UV have been consistently ignored." [1]

April, 2006

Ellsaesser was one of the signatories of the 2006 open letter to Prime Minister Harper that urged inaction on climate policy while denying the existence of human-caused, or anthropogenic, global warming.

May, 2000

Ellsaesser was part of a group created to examine the IPCC's third assessment report. The group was assembled by the Science and Environmental Policy Project (SEPP).

The group contained 14 unnamed "climate scientists" that made up SEPP's "Science Integrity Team." The team set out to present its findings "in plain English" to congress and the media—findings which suggested a lack of significant or human-caused global warming while concluding that "if the earth were to warm slightly, and atmospheric CO2 were to increase, the effects would be mostly beneficial."

Others who participated in SEPP's briefing included David Wojick, Richard Courtney, Vincent Gray, Wibjorn Karlin, Ross McKitrick and numerous other global warming skeptics. [2]
