Italian Climate Scientists Question the Forthcoming IPCC Report
At the first “Climate Dialogues” webinar on May 26, organized by the Padua Association of Engineers and by Galileo magazine, Italian climate scientists exposed the biased climate models used by the IPCC to justify a so-called “climate emergency”, finding the Russian and Chinese climate models more balanced. They also warned that the new IPCC report, expected to be released soon, is based on questionable 2019 charts. Seven additional webinars are planned between now and October.
Prof. Nicola Scafetta, a world expert on climate models based on the sun’s activity, counterposed the models based on CO2 to those using astronomical oscillations. The former are used by the IPCC and are regularly refuted by real data. When applied to the past, they are not able to reproduce past temperatures. In his view, astronomical oscillations (Sun, Earth and other planets) can explain climate cycles much better.
Whereas polls show that 97% of scientists agree that we are in a warming phase, only 26% of them are convinced that human activity is the determinant. Therefore, the famous “consensus” reported by the media is fake news. Professor Scafetta does not exclude a human factor in climate change, but considers it secondary to astronomical causes.
The forthcoming IPCC report, he said, is based on a 2019 chart which is very problematic, because it puts together a series of inconsistent data for the purpose of demonstrating the panel’s hypothesis. It simply ignores, for example, the 1,000-year cycle determined by solar activity.
What is interesting, in his view, are the indices of climate sensitivity that measure climate variations when CO2 doubles, as the Chinese and Russian models show much lower indices than the Western ones. And their results converge on real historical data, and have a higher rate of forecasting actual temperatures.
Professor Scafetta was preceded by Massimo Coccato, chairman of the Padua Association of Engineers, Galileo editor Enzo Siviero and Prof. Alberto Prestininzi, founder and chief editor of the Journal of Engineering Geology and Environment. Both Scafetta and Prestininzi are among the initiators of the 2019 “There Is No Climate Emergency” manifesto of 200 Italian scientists, which had become an international group of over 500 scientists by Oct. 2019. Since then, at least another 300 scientists have signed the manifesto.
Professor Prestinizi regretted the refusal of supporters of man-made climate change to enter into a scientific debate with critics. The discussion occurs in the media instead of within scientific forums, while hundreds of millions of people in the world, whose primary fuel source is coal, still have no adequate access to electricity. He gave a short historical review of climate hysteria, highlighting the example of the “hockey stick” curve, which was ruled to be false even by a court. In 1977, the IPCC forecast a sea level increase of 6 meters by 2030. Eventually, they revised their forecast and the most recent ones say the increase will be between 50 cm and 1 meter.
