Can Scientists Prove man-made global warming?
Written by Kerry Jackson
There’s probably not a phrase that the global warming alarmists and dim celebrities trying to play the role of intellectuals use more than some variation of “the science is settled.” It’s a catchy phrase that’s intended to shut down debate and shame skeptics.
And it’s simply not true.
The alarmist community has had almost three decades to prove its assumptions, and while it is plausible that there has been a small measure of warming, the disaster many predicted hasn’t occurred. Worse for them, it’s impossible to say with any degree of certainty that the warming that has happened — and quite possibly there’s been none at all — was caused by man. Earth’s climate has warmed and cooled throughout its existence. It’s part of the natural cycle.
Yet the alarmist community persists and never acknowledges that it might be wrong. At the same time, when its members are pressed to prove that their one-way beliefs are indeed fact, they can’t do it.
Consider a recent exchange in Australia, in which a skeptic, parliament member Malcolm Roberts, asked scientists at the Commonwealth Scientific and Industrial Research Organization to convince him that there was proof of man-made global warming. With Roberts being a skeptic, the scientists naturally had a high hurdle to clear. But the response Roberts received was not particularly compelling.
The Sydney Morning Herald reported that Alan Finkel responded with the usual stale answers: Atmospheric carbon dioxide traps heat, CO2 emissions have increased, therefore man must be warming his planet.
Then the Morning Herald noted, in a paraphrase, that Finkel conceded that “the effect of warming on climate wasn’t clear.” It followed with a direct quotation from Finkel, which was actually an admission.
“We have models to try to predict what that will be and that’s difficult,” said Finkel.
Difficult. And wrong.
Finkel’s failure to complete the task that Roberts put before him is nothing new nor isolated. Greenpeace co-founder Patrick Moore has said there “is no scientific proof that human emissions of carbon dioxide are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years,” while science writer Michael Fumento wrote convincingly three years ago that proof of global warming was evaporating.
What the alarmists call “proof” and “evidence” is nothing more than conjecture. They cannot prove that man’s activities have warmed the planet, even if the next 100 years are twice as hot as they have predicted. They can lay out their “evidence” as if in a courtroom, and urge the jury to make the connection.
But the fact they can’t get around is that there is more than enough reasonable doubt to throw out their prosecution. Carbon dioxide simply isn’t the only suspect. Earth’s climate system has far too many influences for the inquisitors to settle on just one.
