Der Heidelberger Appell (1992). Die historische Entwicklung der klimaskeptischen Verlautbarungen klärt über die wahren Verhältnisse auf. Es beginnt 1992 in Rio de Janeiro mit der ersten großen UN-Umweltkonferenz. Hier haben die Vertreter von 70 Regierungen und weiteren sogenannten Nichtregierungsinstitutionen (NGOs) vor einer gefährlichen globalen Erwärmung durch die steigende Emission von CO2 in der Atmosphäre infolge Nutzung der fossilen Brennstoffe gewarnt. Drastische Maßnahmen, Energiesteuern und Umweltabgaben wurden gefordert. Als erste Antwort auf die Forderungen von Rio de Janeiro haben ursprünglich 425 Wissenschafter, darunter 62 Nobelpreisträger, den 'Heidelberg Appeal' unterschrieben. Sie fordern, die wissenschaftliche Ehrlichkeit nicht dem politischen Opportunismus und einer irrationalen Ideologie zu opfern. Mittlerweile sind es über 4.000 Wissenschaftler, darunter 72 Nobelpreisträger, die sich skeptisch gegenüber der Klimawissenschaft und Klimapolitik äussern. Darunter sind allein sechs deutsche Nobelpreisträger. 66 der 74 Unterzeichner sind Preisträger in den Naturwissenschaften Physik, Chemie und Medizin.



Background: The Heidelberg Appeal was publicly released at the 1992 Earth Summit in Rio de Janeiro. By the end of the 1992 summit, 425 scientists and other intellectual leaders had signed the appeal. Since then, word of mouth has prompted hundreds more scientists to lend their support. Today, more than 4,000 signatories, including 72 Nobel Prize winners from 106 countries have signed it. In spite of this spontaneous and growing support from the world's scientific community, the Heidelberg Appeal has received little media attention.


Neither a statement of corporate interests nor a denial of environmental problems, the Heidelberg Appeal is a quiet call for reason and a recognition of scientific progress as the solution to, not the cause of, the health and environmental problems that we face. The Appeal expresses a conviction that modern society is the best equipped in human history to solve the world's ills, provided that they do not sacrifice science, intellectual honesty, and common sense to political opportunism and irrational fears.

The Heidelberg Appeal



We want to make our full contribution to the preservation of our common heritage, the Earth.


We are, however, worried at the dawn of the twenty-first century, at the emergence of an irrational ideology which is opposed to scientific and industrial progress and impedes economic and social development.


We contend that a Natural State, sometimes idealized by movements with a tendency to look toward the past, does not exist and has probably never existed since man's first appearance in the biosphere, insofar as humanity has always progressed by increasingly harnessing Nature to its needs and not the reverse. We full subscribe to the objectives of a scientific ecology for a universe whose resources must be taken stock of, monitored and preserved.


But we herewith demand that this stock-taking, monitoring and preservation be founded on scientific criteria and not on irrational preconceptions.


We stress that many essential human activities are carried out either by manipulating hazardous substances or in their proximity, and that progress and development have always involved increasing control over hostile forces, to the benefit of mankind.


We therefore consider that scientific ecology is no more than extension of this continual progress toward the improved life of future generations.


We intend to assert science's responsibility and duties toward society as a whole.


We do, however, forewarn the authorities in charge of our planet's destiny against decisions which are supported by pseudoscientific arguments or false and nonrelevant data.


We draw everybody's attention to the absolute necessity of helping poor countries attain a level of sustainable development which matches that of the rest of the planet, protecting them from troubles and dangers stemming from developed nations, and avoiding their entanglement in a web of unrealistic obligations which would compromise both their independence and their dignity.


The greatest evils which stalk our Earth are ignorance and oppression, and not Science, Technology, and Industry, whose instruments, when adequately managed, are indispensable tools of a future shaped by Humanity, by itself and for itself, overcoming major problems like overpopulation, starvation and worldwide diseases.
