A meteorologist and an analytical chemist teamed up explore the claims that CO2 levels drive climate. (They also mention the role of underwater volcanoes, a drum that I have been beating for more than 20 years.)

In their newly published paper, ‘Role of atmospheric carbon dioxide in climate change‘, meteorologist Dr Martin Hertzberg and analytical chemist Hans Schreuder cite a plethora of data concerning what is known – and currently accepted – about the role of carbon dioxide in climate change (global warming).

The data examined includes:

(a) Vostok (Antarctica) ice-core measurements;

(b) rising CO2 levels in the atmosphere;

(c) temperature changes that precede CO2 changes;

(d) global temperature trends;

(e) satellite data;

(f) effect of solar activity.

The two highly qualified scientists found that:

“Nothing in the data supports the supposition that atmospheric CO2 is a driver of weather or climate, or that human emissions control atmospheric CO2.”

Any changes in CO2 levels are “overwhelmingly natural.”

Looking at the relationship between CO2 and climate over the past 400,000 years, the data indicate that human-caused CO2 emissions had no influence on the Earth’s temperature,

Even though CO2 levels doubled during warming periods in the past 400,000 years, any change in climate  could not have come from human emissions, which were essentially nil.

“Empirical evidence does not support the claim that anthropogenic CO2 emissions cause global warming and/or climate change.

“The preponderance of evidence suggests that human emission is not a significant factor in the increase (of CO2 levels).”

“Fossil fuels are not a significant source of atmospheric CO2,” the authors insist. Instead, forces and motions in the oceans and atmosphere are driven mainly by the following:

•   The motions of the Earth relative to the Sun

•   Variations in solar activity

•   The distribution of land and water on the Earth’s surface,

•   Motions within the Earth’s oceans that determine moisture content and ocean surface temperatures (El Nino and La Nina).

•   Volcanic eruptions

•   Underwater volcanic eruptions, including ‘black smokers’ that spew super-heated water continuously. Underwater volcanoes are expected to number in the hundreds of thousands.

The two long-time scientists also found that changes in temperature almost always preceded changes in CO2 levels, meaning that global warming alarmists have it backward. Carbon dioxide levels do not drive the climate. Instead, CO2 levels respond to climate.

Even during the last 59 years, the authors found a negative correlation between CO2 levels and climate.

See entire paper:

Martin Hertzberg was first trained as a meteorologist at the US Naval Postgraduate School and served as a forecasting and research aerologist at the Fleet Weather Central in Washington DC. He subsequently obtained a PhD in Physical Chemistry at Stanford and later served as a Fulbright Professor.

Dr Hertzberg established and supervised the explosion testing laboratory at the U. S. Bureau of Mines facility in Pittsburgh (now NIOSH). Test equipment developed in that laboratory has been widely replicated and incorporated into ASTM standards. Published test results from that laboratory are used for the hazard evaluation of industrial dusts and gases. He is an internationally recognized expert on combustion, flames, explosions and fire research with over 100 publications in those areas. While with the Federal Government he served as a consultant for several Government Agencies (MSHA, DOE, NAS) and professional groups (such as EPRI). He is the author of two US patents: (1) sub-micron particulate detectors, and (2) multi-channel infra-red pyrometers.

Hertzberg is also a long time climate writer and is a well-published skeptic of anthropogenic global warming/climate change.

Hans Schreuder trained as an analytical chemist in The Hague and spent 15 years working in that field, testing pharmaceutical products as well as researching the recycling of plastics and rubber. For another 15 years, he gained extensive experience as an international technical contractor, including writing quality control manuals whilst working in South Africa. He was accepted as a member of MENSA after passing the relevant tests.

Schreuder has long been a staunch and highly regarded critic of the greenhouse gas theory and outspoken commentator, using his two websites as a publishing hub for fellow scientists critical of the theory. Schreuder has written many articles on the subject and in May 2009 submitted a 109-page written report, supplemented with a 45-min oral submission, to the Northern Ireland Climate Change Committee.
