An alarmist’s solution to criticism

    Unless you’re among those who follow the global warming controvery with considerably more intensity than the average citizen, the name James Hansen probably doesn’t ring any bells. But it should.

    Hansen is the original global warming alarmist. He is currently the head of the National Aeronautics and Space Administration’s Goddard Institute for Space Studies. Twenty years ago, in an appearance before several Congressional committees, Hansen warned that increasing human-generated CO2 content in the earth’s atmosphere was pushing up global temperatures, and that if generation of CO2 wasn’t cut back, we would face a “tipping point” from which there could be no return, and that the result of warming would doom life on earth as we know it.

    He was called to testify in the early ’80s because in 1981 he and a team of scientists at Goddard had concluded that carbon dioxide in the atmosphere would lead to global warming sooner than previously predicted. While other climatologists had already predicted that a trend would be apparent by 2020, Hansen predicted, in a paper published in Science, that the change was already occurring and that there would be record high temperatures as early as 1990.

    In June of this year Hansen again testified before a Congressional committee, on the anniversary of his first alarmist appearance. And what has happened to global temperatures in the intervening 20 years? According to the University of Alabama at Huntsville, global satellite temperature data show that earth’s temperature has indeed changed; it’s gone down by half a degree (Fahrenheit). So much for Hansen’s prediction about tipping points, and carbon dioxide dangers, etc., etc.

    But Hansen also did something else at in June. At an informal media event hosted by Worldwatch Institute, an environmental activist group, he called for criminal trials against scientists, corporate executives, and public policy advocates who disagree with him. He said skeptics are guilty of “crimes against humanity.” If you oppose his theories, in other words, you’re no better than Hitler, Stalin, Robert Mugabe, Papa Doc Duvalier, and the rest of history’s mass murderers, and ought to be sent to jail — or worse — for holding such views.

    Much of the above is from the August issue of Environment & Climate News, a Heartland Institue publication. The Heartland Institute, you may not know, is a non-profit environmental organization that challenges global warming theories. Two letters to the editor today take note of a story published in the Sunday Press Dispatch (albeit buried on D7) that some 31,072 American scientists have signed a petition rejecting Hansen’s — among others — assertions that global warming has reached a crisis stage that is caused by human activity. The story about the petition originated with the Heartland Institute.

    The petition puts the lie to claims such as the one by Al Gore (“The debate is over”) that there’s any sort of general agreement among the world’s scientific community about global warming, either as to what is causing it, that it’s in fact happening, or that there’s anything humanity can do about it.

    Hansen, you might also want to know, is indeed a scientist. He’s an astronomer. But stifling dissent of his theories by shouting, “Off with their heads” does not exactly comport with scientific method. So it’s no surprise to also learn he’s Al Gore’s adviser on science. Uh huh.

Answer 3

You won't find any credible links either way because scientists don't believe or deny anything, they either prove or disprove a hypothesis. Currently, most scientists believe that some or most of the warming of the past century was due to human use of fossil fuels for energy. They don't agree on how certain they are of this, let alone how much of the warming is due to this. We can measure how much CO2 is in the air but we have a hard time even attributing the sources since nature continually releases and reasbsorbs CO2.

Benjamin and no doubt others will post links to groups and individuals who purportedly believe in global warming. The problem is this: if there were a definite consensus among all these scientists, why haven't they just asked them to fill out a poll about warming? Instead we see trade groups, think tanks, politicians and political entities, universities and other groups claiming there is global warming. But how many of their individual members agree with what is said in their name? It's impossible to say because like the IPCC summary reports, these warnings, claims and conclusions are written up by a small group, not the group at large.

Criticizing the Petition Project which requires a positive effort on the part of all participants while citing public statements made by the leaders of various organizations (not necessarily of the majority of it's members) is a curious practice.

Answer 4

I don't think anyone knows the exact numbers of all the scientists in the world who believes and who doesn't.

What I do know is that ALL major scientific organizations (NAS, AAAS, NASA...) say that global warming is real, man's fault, and will have bad consequences if we don't act soon.
