In an article that has already and not unexpectedly received some sharp criticism from climatologists. two researchers in Finland have just published an paper that says human activity is a tiny cause of what is in fact real global warming.
Jyrki Kauppinen and Pekka Malmi, from the Department of Physics and Astronomy at the University of Turku, published their research paper in late June and argue that that the idea of man-made climate change is a miscalculation or skewing of formulas by the UN’s Intergovernmental Panel on Climate (IPCC).
More specifically, the paper says the IPCC failed to calculate the influences of low cloud cover changes on the global temperature – and as a result assigned far too great an influence of greenhouse gases associated with human activities and use of fossil fuels.
The IPCC has to “use a very large sensitivity [to man-made CO2] to compensate for a too small natural component. Further they have to leave out the strong negative feedback due to the clouds in order to magnify the sensitivity.” In addition, Kauppinen and Malmi claim that their paper proves that “the changes in the low cloud cover fraction practically control the global temperature.”
They add that “The IPCC climate sensitivity is about one order of magnitude (i.e. 10 times) too high, because a strong negative feedback of the clouds is missing in climate models.”
All this would obviously turn mainstream global warming on its head.
Going even further, Kauppinen and Malmi claim say their research shows that “anthropogenic [man-made] climate change does not exist in practice.”
What’s more, another recent paper authored by scientists from Japan comes to largely the same conclusion.
“The Intergovernmental IPCC has discussed the impact of cloud cover on climate in their evaluations, but this phenomenon has never been considered in climate predictions due to the insufficient physical understanding of it,” Dr. Masayuki Hyodo of the University of Kobe.
Hyodo added that “When galactic cosmic rays increase, so do low clouds, and when cosmic rays decrease clouds do as well, so climate warming may be caused by an opposite-umbrella effect. The umbrella effect caused by galactic cosmic rays is important when thinking about current global warming as well as the warm period of the medieval era.”
The low cloud cover is caused by increasing cosmic rays reaching earth due to changes in the earth’s magnetic field.
The research findings did not go over so well in many circles.
The Helsinki Times, for example, says the paper by Kauppinen and Malmi has been criticized for not being peer reviewed, while other climate scientists have refuted the conclusions reached by Kauppinen and Malmi.
Critics have said that in addition to not being peer reviewed, Malmi and Kauppinen fail to provide correct physical explanation, have not linked to- or cited to enough sources to support their claims, and despite denouncing climate models, they use one themselves to prove their own points.
So will this research from Finland and Japan have an impact on the direction of global warming investigation going forward – or slip quietly into the dust bin of research history?
We will keep you posted, but will note that a 2018 article in Cosmos magazine said that “Understanding clouds, circulation and climate sensitivity is one of several grand challenges that the Swiss-based World Climate Research Program (WCRP) is focusing on. The program brings together scientists from all over the world to tackle big questions in climate science, and it considers cloud feedback “the intellectual and experimental challenge of our lifetime.”
