(NationalSentinel) Even as Democrat-run states continue to adopt costly policies including tax hikes and ‘cap and trade’ schemes to combat ‘human-caused climate change,’ a new study by Finnish researchers found that human activity isn’t responsible.
A newly-published paper titled “No experimental evidence for the significant anthropogenic climate change” by Jyrki Kauppinen and Pekka Malmi 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 further 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 paper’s abstract notes:
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 a very 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.
Note that the researchers call into question the United Nations’ IPCC, which regularly claims that humans are causing the climate to dramatically change.
The researchers conclude:
We have proven that the GCM-models used in IPCC report AR5 cannot compute correctly the natural component included in the observed global temperature. The reason is that the models fail to derive the influences of low cloud cover fraction on the global temperature.
A too small natural component results in a too large portion for the contribution of the greenhouse gases like carbon dioxide. That is why IPCC represents the climate sensitivity more than one order of magnitude larger than our sensitivity 0.24°C. Because the anthropogenic portion in the increased CO2 is less than 10 %, we have practically no anthropogenic climate change. The low clouds control mainly the global temperature.
And while all scientific results are subject to debate, this study proves — again — that no, there isn’t any “consensus” on human-caused climate phenomena, and certainly not enough to implement expensive tax schemes that stifle economic growth, bring more Americans under the thumb of big government, and do nothing, literally, to affect the Earth’s ever-changing climate.
