The uncertainty of science: In a commentary published in the science journal Nature last week, a scientist admitted that the worse case global warming prediction, cited more the 2,500 times in the literature and a favorite of politicians and global warming activists, is not likely to happen and should no longer be referenced.
What is surprising here is not the discovery that this climate computer model doesn’t work, but that Nature was willing to publish the admission, and that this scientist, who still fears human-caused global warming, was willing to write it. The major science journals have in recent years taken sides in this scientific field, advocating the theory that increased carbon dioxide will cause the climate to warm, something no journal should ever do.
The article however has this quote that clearly illustrates the uncertainties of all climate predictions:
Scientists are still uncertain as to how sensitive global temperatures are to a doubling of CO2 in the atmosphere. The value, known as the Charney Sensitivity still isn’t known for certain, over 40 years after it was first introduced in 1979 by the United States National Academy of Sciences and chaired by Jule Charney. He estimated climate sensitivity to be 3 °C (5.4 °F), give or take 1.5 °C (2.7 °F).
Without knowing the true climate warming response to increased CO2, essentially all climate models become a crap-shoot. It is a glaring illustration of just how imprecise climate science actually is.
Note that this area of ignorance is only one of many. We don’t know the influence of pollution on the climate. We don’t know the influence of the Sun on the climate. And we don’t know the influence of clouds on the climate. And I could go on.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
