Global Science Report is a feature from the Center for the Study of Science, where we highlight one or two important new items in the scientific literature or the popular media. For broader and more technical perspectives, consult our monthly “Current Wisdom.”
Climate alarmism is like one of those pop-up Bozos. No matter how many times you bop it, up it springs. In fact, the only way to stop it, as most kids learn, is to deflate it. In this case, the air inside Bozo is your and my tax money.
Two scientific papers released last week combine for a powerful 1-2 haymaker, but, rest assured, Bozo springs eternal. The first says that human aerosol emissions are not that responsible for offsetting the warming influence of greenhouse gas emissions, while the second finds that the observed warming from human greenhouse gases is less than a lot of people think.
We aren’t at all surprised by the first result. The cooling effect of sulphate particulates, which go into the air along with carbon dioxide when fossil fuels (mainly coal) are combusted, was only invoked in the mid-1980s, when the lack of warming predicted by computer models was embarrassingly obvious.
This is the kind of thing that the iconic historian of science, Thomas Kuhn, predicted in his classic book, The Structure of Scientific Revolutions. When a scientific “paradigm” is assaulted by reality, increasingly ornate and bizarre explanations are put forth to keep it alive. Sulfates smelled like one of those to us back in the 1980s, and now it looks like the excuses are finally getting comeuppance.
The second result also comes as little news to us, as we have been saying for years that the human carbon dioxide emissions are not the only player in the climate change game.
The two new papers, in combination, mean that the human influence on the climate from the burning of fossil fuels is far less than what the IPCC’s ensemble of climate models says it is. This also goes for the U.S. Global Change Research Program, the EPA ,and the White House.
Rest assured, though, Bozo will rise again—despite a near-continuous barrage of blows supporting the idea that the climate’s sensitivity to human greenhouse gas emissions is far too low to justify any of the expensive and futile actions emanating from Washington and Brussels.
