Than 1000 International Scientists Dissent Over Man-Made Global ...

Ivy League Organic Chemist Dr. D. Bruce Merrifield is a former Undersecretary of
Commerce for Economic Affairs, Professor Emeritus of the Wharton School of
Business at the University of Pennsylvania, and a member of the Visiting Committee
for Physical Sciences at the University of Chicago. "The earth has been subjected to
many warming and cooling periods over millions of years, none of which were of human
origin," Merrifield wrote on July 11, 2007. "Data from many independent sources have
mutually corroborated these effects. They include data from coring both the Antarctic ice
cap and sediments from the Sargasso Sea, from stalagmites, from tree rings, from upwellings
in the oceans, and from crustaceans trapped in pre-historic rock formations. The
onset of each 100,000-year abrupt warming period has been coincident with emissions into
the atmosphere of large amounts of both carbon dioxide and methane greenhouse gases,
which absorb additional heat from the sun, a secondary warming effect," he explained.
"Solar radiation would appear to be the initial forcing event in which warming oceans
waters release dissolved carbon dioxide, and melt methane hydrates, both of which are
present in the oceans in vast quantities. Subsequent declines in radiation are associated with
long cooling periods in which the green house gases then gradually disappear (are reabsorbed)
into terrestrial and ocean sinks, as reflected in the data from coring the Antarctic
Ice Cap and Sargasso Sea," he added. "The current 100 year solar radiation cycle may now
have reached its peak, and irradiation intensity has been observed to be declining. This
might account for the very recent net cessation of emission of green house gases into the
atmosphere starting about 1988, in spite of increasing generation of anthropomorphicallysourced
industrial-based green house gases. While it seems likely that solar radiation,
rather than human activity, is the ‗forcing agent' for global warming, the subject surely
needs more study," he concluded. (LINK)
Oxford-educated Geochemist Dr. Cal Evans, a prominent researcher who has advised
the Alberta Research Council, the Natural Sciences, and Engineering Research
Council of Canada, and who is affiliated with the Calgary-based group Friends of
Science, dismissed climate fears in 2007. "The primary process that governs global
temperature cycles has been identified - it's a combination of solar irradiation and highenergy
cosmic rays. Carbon dioxide appears to be a very minor factor. Although the
political forces that support the CO2 theory remain formidable, the science has turned
decisively against them," Evans said according to an article on July 9, 2007. "Yes, there's
been an increase [in CO2] but the quantity remains extremely small, no more than a trace
element," Evans said. "Whatever causes global warming must involve clouds and other
atmospheric vapour. To date, no one has been able to identify a link between higher CO2
concentrations and greater volumes of atmospheric water vapour," he added. "The slight
increase in ground temperature has no parallel in the troposphere. If atmospheric CO2
concentration was actually a significant factor in global warming, it stands to reason that
atmospheric temperatures would rise but that hasn't happened," he said. "It's ironic that
CO2 propaganda has achieved an unprecedented degree of political penetration in Canada
and the United States precisely at the same time that the scientific case is melting away.
Billions of dollars in research funding and related activity are at stake, and so are a great
many professional reputations. So the truth will certainly be inconvenient for someone, and
the struggle won't end for a while yet. Eventually, however, the facts will make themselves
known," he concluded. (LINK)
