A new study by researchers at Turku University in Finland found that the human contribution to a rise of 0.1°C in global temperatures over the last century is just 0.01°C. The paper, titled ‘No experimental evidence for the significant anthropogenic climate change’ was published by Jyrki Kauppinen and Pekka Malmi. The study found that, “During the last hundred years the temperature is increased about 0.1°C because of carbon dioxide. The human contribution was about 0.01°C.”
Kauppinen and Malmi conclude that global temperatures are controlled primarily by cloud cover and that “only a small part” of the increased carbon dioxide concentration is anthropogenic. The study also calls into question the claims of the UN IPCC, which concluded that global temperatures are largely driven by human activity. While the methods and results of the study can be debated, this once again illustrates how there is no overwhelming consensus on man-made global warming as the media often claims. In reality, there are dozens of prominent scientists who believe that climate change is driven by natural forces or that the United Nations’ climate projections are unreliable.

In this paper we will prove that GCM-models used in IPCC report AR5 fail to calculate the influences of the low cloud cover changes on the global temperature. That is why those models give a very small natural temperature change leaving a very large change for the contribution of the green house gases in the observed temperature. This is the reason why IPCC has to use avery large sensitivity to compensate 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, this paper proves that the changes in the low cloud cover fraction practically control the global temperature.
