What About “Climate
Change”?
Climate Has Always Been Changing
• 200 B.C. to A.D. 500 Roman “warm period”
• A.D. 500 to A.D. 900 Post-Roman “cooling
period”
• 900 to 1350 Medieval “warm period”
• 1350 to 1850 “Little Ice Age”
• 1850 to present “warming period”

Stark, How the West Won, Chap 7
“If historians have been rather inattentive to matters of
geography, they have been even less attuned to the
implications of climate and disease. Of course, the
obvious effects of climate . . .have always been noted.
What has been given little attention are significant
climatic changes. In part this is because until Hubert
Lamb wrote about them in 1965, it was not widely
recognized that there had been any substantial climatic
changes since the end of the Ice Age, . . .despite the fact
that the history of medieval Europe hinges on two major
shifts in climate. . . .
Amid the bitter contemporary conflicts over whether the
climate is getting warmer, and if so why, the most basic
fact about earth’s climate has been nearly forgotten: that
warming and cooling trends are quite common.”

Problems with Government-Funded
Science
President
Eisenhower’s
1961 Farewell Speech
(with the famous
“military-industrial
complex” warning)
“In this [technological] revolution,
research has become central; it
also becomes more. . .costly. . .
.Partly because of the huge costs
involved, a government contract
becomes a substitute for
intellectual curiosity. . . .The
prospect of domination of the
nation’s scholars by federal
employment, project allocations,
and the power of money is ever
present. . . .Public policy could
itself become the captive of a
scientific-technological elite”.
Declaración de Margarita sobre
Cambio Climático
“The structural causes of climate change are
linked to the current capitalist hegemonic
system. . . .To combat climate change it is
necessary to change the system”
Venezuela UN-sponsored conference on climate
15-18 July 2014
Signed by 130 environmentalist groups
Political goals trump telling the truth
“To capture the public imagination, we have to
offer up scary scenarios, make simplified
dramatic statements, and make little mention of
any doubts we may have. Each of us has to
decide what the right balance is between being
effective and being honest.”
A leading proponent of global warming, Steven Schneider of
Stanford, in Discover magazine (1989)

Scientific “accomplishment”: 0.02˚C reduction in
global average temperature by the end of this
century
Economic impacts:
•$50 billion per year
•600,000 jobs lost
•$1,200 per year in reduced income for the average
family of four
Proposed ruling to cut CO2 emissions from power plants by 30% by
2030.
Conclusions:
1. Climate is changing and has always been
changing
Therefore, causes of the change exist other
than increasing CO2 emissions by man.
2. Climate models are incomplete and
underperforming
Therefore, policies that so drastically hurt the
underdeveloped poor nations and the laboring
families of our country, are too risky and ought
not to be implemented.
