Award-winning Astrophysicist Dr. Shaviv is in Germany with many other skeptical scientists during the UN climate summit. Shaviv is warning about the scientific fallacies presented by the UN IPCC panel about global warming climate change. His full presentation at the conference is on November 10th.
Dr. Nir Shaviv on Cambridge Debate: 'I was quite shocked to see how the audience was so one sided (though far less than the ridiculous 97:3 ratio we hear about!) and unwilling to listen to scientific arguments.'
Dr. Shaviv's Key scientific points: 'Evidence for warming is not evidence for warming by humans.'
'Anyone who appeals to authority or to a majority [97% claims] to substantiate his or her claim is proving nothing.'
'The polar bear population is now probably at its highest in modern times!'
'There is no single piece of evidence that proves that a given amount of CO2 increase should cause a large increase in temperature.'
'Over geological time scales, there were huge variations in the CO2 (a factor of 10) and they have no correlation whatsoever with the temperature. 450 million years ago there was 10 times as much CO2 in the atmosphere but more extensive glaciations.'
'The simple truth is that in the height of the middle ages it was probably just as warm as the latter half of the 20th century'
'Taking unnecessary precautionary steps when we know they are unnecessary is immoral. It is even committing statistical murder.'
'Let us use our limited resources to treat real problems.'
The Sun as climate driver is repeatedly discussed in the literature but proofs are often weak. In order to elucidate the solar influence, we have used a large number of temperature proxies worldwide to construct a global temperature mean G7 over the last 2000 years. The Fourier spectrum of G7 shows the strongest components as ~1000-, ~460-, and ~190 - year periods whereas other cycles of the individual proxies are considerably weaker. The G7 temperature extrema coincide with the Roman, medieval, and present optima as well as the well-known minimum of AD 1450 during the Little Ice Age. We note that the temperature increase of the late 19th and 20th century is represented by the harmonic temperature representation, and thus is of pure multiperiodic nature. It can be expected that the periodicity of G7, lasting 2000 years so far, will persist also for the foreseeable future. It predicts a temperature drop from present to AD 2050, a slight rise from 2050 to 2130, and a further drop from AD 2130 to 2200. --Horst-Joachim Lüdecke and Carl-Otto Weiss, The Open Atmospheric Science Journal (11) 2017.
