Finnish study finds 'practically no' evidence for man-made climate change
In a paper published late last month, entitled ‘No experimental evidence for the significant anthropogenic climate change’, a team of scientists at Turku University in Finland determined that current climate models fail to take into account the effects of cloud coverage on global temperatures, causing them to overestimate the impact of human-generated greenhouse gasses.
Models used by official bodies such as the Intergovernmental Panel on Climate Change (IPCC) “cannot compute correctly the natural component included in the observed global temperature,” the study said, adding that “a strong negative feedback of the clouds is missing” in the models.
Adjusting for the cloud coverage factor and accounting for greenhouse gas emissions, the researchers found that mankind is simply not having much of an effect on the Earth’s temperature.
The study’s authors make a hard distinction between the type of model favored by climate scientists at the IPCC and genuine evidence, stating “We do not consider computational results as experimental evidence,” noting that the models often yield contradictory conclusions.
Given the evidence presented in the study, the Finnish team rounded out the paper by concluding “we have practically no anthropogenic climate change,” adding that “the low clouds control mainly the global temperature.”
The results sharply cut against claims put forward by many environmentalists, including US lawmakers such as Alexandria Ocasio-Cortez, who argue not only that climate change is an immediate threat to the planet, but that it is largely a man-made phenomenon. Ocasio-Cortez, better known as ‘AOC’, has proposed a ‘Green New Deal’ to address the supposedly dire threat.
Japanese researchers at the University of Kobe arrived at similar results as the Turku team, finding in a paper published in early July that cloud coverage may create an “umbrella effect” that could alter temperatures in ways not captured by current modeling.
