Stance on Climate Change

“There has been a stunning disconnect involving land temperatures globally and CO2, whether man-made or naturally sourced.  The oceans continue to warm, while the surface record flatlines… . It is obvious that the surface records are NOT going up - they are basically in a 0.2C flatline …” [3]

Key Quotes

“If CO2 is to be considered a major driver of temperatures, it is doing a counterintuitive dance around the numbers.” [3]

Key Deeds


Wysmuller gives regular lectures on Global Warming to universities, high schools, and public/private organizations.

Wysmuller was a speaker at the Heartland Institute's Seventh International Conference on Climate Change (ICCC7).

A Heartland press release implies that he was a “Former NASA scientist,” although according to his website, his highest position was as an intern. [4]

Wysmuller was one of 49 former “NASA scientists” to sign an open letter to NASA and the Goddard Institute for Space Studies (GISS) to cease they describe as “unbridled advocacy of CO2 being the major cause of climate change.” [5]

“We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated,” the letter stated.

SkepticalScience published a critique of the letter which was republished in The Guardian. [6], [7]
