Researchers who have predicted a long term solar minimum or ‘solar hibernation’ and/or a new climate change to a period of long lasting cold weather based upon solar activity. 

1. Dr. Habibullo I. Abdussamatov: Russian Academy of Scientists. Head of space research at the Pulkova Observatory, St. Petersburg.

Comment: RIA Novosti, August 25, 2006: “Khabibullo Abdusamatov said he and his colleagues had concluded that a period of global cooling similar to one seen in the late 17th century – when canals froze in the Netherlands and people had to leave their dwellings in Greenland – could start in 2012-2015 (sic) and reach its peak in 2055-2060….He said he believed the future climate change would have very serious consequences and that authorities should start preparing for them today….”

2.  David Archibald. Summa Development Limited. (Australia).

     From his paper: Archibald, D.C., (2006), Solar Cycles 24 and 25 and predicted climate response, Energy and Environment, Vol.17, No.1.

     Comment from paper: “Based on a solar maxima of approximately 50 for solar cycles 24 and 25, a global temperature decline of 1.5C is predicted to 2020 equating to the experience of the Dalton Minimum.”

 3. Dr. O.G.Badalyan, and Dr.V.N. Obridko, Institute of Terrestrial Magnestism. Russia, Dr.J.Sykora. Astronomical Institute of the Slovak Academy of Sciences, Slovak Republic.

     From their paper: Balalyan, O.G., V.N. Obridko, and J. Sykora, (2000), Brightness of the coronal green line and prediction for activity cycles 23 and 24, Solar Physics, 199: pp.421-435.

Comment from paper: “ A slow increase in (intensity of coronal green line) in the current cycle 23 permits us to forecast a low-Wolf-number (number of sunspots) cycle 24 with the maximum W~50 at 2010-2011.” (Note: a 50 sunspot level is a Dalton class minimum)

 4. Dr. B. P. Bonev,  Dr. Kaloyan M. Penev, Dr. Stefano Sello.

    From their paper: Bonev, B.P., et. al., (2004), Long term solar variability and the solar cycle in the 21st century, The Astrophysical Journal, Vol. 605, pp.L81-L84.

Comment from their paper: “…we conclude that the present epoch is at the onset of an upcoming local minimum in long term solar variability.”

 5. John L. Casey, President, Space and Science Research Corporation. Orlando, Florida

    From his research report: Casey, John L. (2008), The existence of ‘relational cycles’ of solar activity on a multi-decadal to centennial scale, as significant models of climate change on earth. SSRC Research Report 1-2008 – The RC Theory, www.spaceandscience.net. Comments from the research report:

“ As a result of the theory, it can be predicted that the next solar minimum may start within the next 3-14 years, and last 2-3 solar cycles or approximately 22-33 years. …It is estimated that there will be a global temperature drop on average between 1.0 and 1.5 degrees C, if not lower, at least on the scale of the Dalton Minimum. …This forecast next solar minimum will likely be accompanied by the coldest period globally for the past 200 years and as such, has the potential to result in world wide, agricultural, social, and economic disruption.”


6. Dr. Peter Harris. Engineer, retired, Queensland, Australia.

From his analysis of glacial and interglacial cycles he concludes: “…we can say there is a probability of 94% of imminent global cooling and the beginning of the coming ice age.”


7. Victor Manuel Velasco Herrera. Researcher at the National Autonomous University of Mexico.

His comments from his research released in August 2008: “…in two years or so, there will be a small ice age that lasts for 60-80 years.”


8. Dr’s. Y.T.Hong, H.B. Jiang, T.S. Liu, L.P.Zhou, J.Beer, H.D. Li, X.T.Leng, B.Hong, and X.G. Qin.

From their paper: Response of climate to solar forcing recorded in 6,000-year (isotope) O18 time-series of Chinese peat cellulose. The Holocene 10.1 (2000) pp. 1-7.

The Chinese team of researchers observed “…a striking correspondence of climate events to nearly all of the apparent solar activity changes.”

In showing O18 isotope measurements were high during the coldest periods they concluded, “If the trend after AD 1950 continues…the next maximum of the peat O18 (and therefore cold maximum) would be expected between about AD 2000 and AD 2050.”
