"a mathematics prodigy who came to this country at 23 and right away contributed seminal work to physics by unifying quantum and electrodynamic theory — [who] not only did path-breaking science of his own; he also witnessed the development of modern physics, thinking alongside most of the luminous figures of the age, including Einstein, Richard Feynman, Niels Bohr, Enrico Fermi, Hans Bethe, Edward Teller, J. Robert Oppenheimer and Edward Witten, the “high priest of string theory” whose office at the institute is just across the hall from Dyson’s. Yet instead of hewing to that fundamental field, Dyson chose to pursue broader and more unusual pursuits than most physicists — and has lived a more original life. Among Dyson’s gifts is interpretive clarity, a penetrating ability to grasp the method and significance of what many kinds of scientists do. His thoughts about how science works appear in a series of lucid, elegant books for nonspecialists that have made him a trusted arbiter of ideas...."The article goes on to explian, "Dyson may be an Obama-loving, Bush-loathing liberal who has spent his life opposing American wars and fighting for the protection of natural resources, but he brooks no ideology and has a withering aversion to scientific consensus."
"Dyson agrees with the prevailing view that there are rapidly rising carbon-dioxide levels in the atmosphere caused by human activity. To the planet, he suggests, the rising carbon may well be a MacGuffin, a striking yet ultimately benign occurrence in what Dyson says is still “a relatively cool period in the earth’s history.” The warming, he says, is not global but local, “making cold places warmer rather than making hot places hotter.” Far from expecting any drastic harmful consequences from these increased temperatures, he says the carbon may well be salubrious — a sign that “the climate is actually improving rather than getting worse,” because carbon acts as an ideal fertilizer promoting forest growth and crop yields. “Most of the evolution of life occurred on a planet substantially warmer than it is now,” he contends, “and substantially richer in carbon dioxide.”
"Dyson says he doesn’t want his legacy to be defined by climate change, but his dissension from the orthodoxy of global warming is significant because of his stature and his devotion to the integrity of science. Dyson has said he believes that the truths of science are so profoundly concealed that the only thing we can really be sure of is that much of what we expect to happen won’t come to pass.... When Dyson joins the public conversation about climate change by expressing concern about the “enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories,” these reservations come from a place of experience. Whatever else he is, Dyson is the good scientist; he asks the hard questions."
And this sentence echoes my claim of there being "two sides" to this debate; something my science friend, Tamsin, took me to task for when I suggested it:
"Dyson strongly disagrees with each of these points [the extreme predictions made by GW Alarmists], and there follows, as you move back and forth between the two positions, claims and counterclaims, a dense thicket of mitigating scientific indicators that all have the timbre of truth and the ring of potential plausibility."Science is provable, and where it can be verifiable, is not open for debate. However, that's the biggest problem with Global Warming - most of it is not based on science, but on models.
"Climate models, he says, take into account atmospheric motion and water levels but have no feeling for the chemistry and biology of sky, soil and trees. “The biologists have essentially been pushed aside,” he continues. “Al Gore’s just an opportunist. The person who is really responsible for this overestimate of global warming is Jim Hansen. He consistently exaggerates all the dangers.”
And this is why the "science" is debated; because it's not fully scientific. The article continues:
"Beyond the specific points of factual dispute, Dyson has said that it all boils down to “a deeper disagreement about values” between those who think “nature knows best” and that “any gross human disruption of the natural environment is evil,” and “humanists,” like himself, who contend that protecting the existing biosphere is not as important as fighting more repugnant evils like war, poverty and unemployment.
"Dyson has always been strongly opposed to the idea that there is any such thing as an optimal ecosystem — “life is always changing” — and he abhors the notion that men and women are something apart from nature, that “we must apologize for being human.” Humans, he says, have a duty to restructure nature for their survival.
