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. ” 6

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)
Obama Administration Environmental Protection Agency 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 CO 2 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 CO 2 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.
