The following comment by Allan MacRae has been upgraded to a post:
In 2003, Dr. Theodor Landscheidt wrote a paper predicting serious global cooling: “… a long period of cool climate with its coldest phase around 2030 is to be expected.”
In 2005, Piers Corbyn predicted cooling by 2040.
Khabibullo Abdusamatov and colleagues at the Russian Academy of Science stated in 2006:
“Global cooling could develop on Earth in 50 years and have serious consequences …”
Nigel Weiss, University of Cambridge, stated in 2006:
“If you look back into the sun’s past, you find that we live in a period of abnormally high solar activity. Periods of high solar activity do not last long, perhaps 50 to 100 years, then you get a crash. It’s a boom-bust system, and I would expect a crash soon.”
Leif Svalgaard, Stanford University, stated in 2006:
“Sunspot numbers are well on the way down in the next decade. Sunspot numbers will be extremely small, and when the sun crashes, it crashes hard. The upcoming sunspot crash could cause the Earth to cool.”
In 2007, Lin Zhen-Shan and Sun Xian wrote in “Multi-scale analysis of global temperature changes and trend of a drop in temperature in the next 20 years”:
“… Signs also show a drop in temperature in China on century scale in the next 20 years.”
MORE PREDICTIONS OF GLOBAL COOLING:
THE NEW LITTLE ICE AGE HAS STARTED
H. I. Abdussamatov 2016
“The quasi-centennial epoch of the new Little Ice Age has started at the end 2015 after the maximum phase of solar cycle 24.
PROFESSOR VALENTINA ZHARKOVA: “WE ENTERED THE ‘MODERN’ GRAND SOLAR MINIMUM ON JUNE 8, 2020”
“Modern Grand Solar Minimum will Lead to Terrestrial Cooling“. Published on August 4, 2020, Zharkova’s latest analysis suggests that June 8, 2020 was the date on which we entered the Modern (Eddy) Grand Solar Minimum.”
The opening paragraph reads:
In this editorial I will demonstrate with newly discovered solar activity proxy-magnetic field that the Sun has entered into the modern Grand Solar Minimum (2020–2053) that will lead to a significant reduction of solar magnetic field and activity like during Maunder minimum leading to noticeable reduction of terrestrial temperature.
Dr Zharkova’s co-author Dr Yelena Popova was interviewed about their 2015 paper predicting global cooling, starting circa 2020.
My good friend Willie Soon and co-authors published August 1, 2021:
“In addition, our ML model forecasts a new phase of extended solar minima that began prior to Sunspot Cycle 24 (ca. 2008–2019) and will persist until Sunspot Cycle 27 (ca. 2050 or so).”
DOES MACHINE LEARNING RECONSTRUCT MISSING SUNSPOTS AND FORECAST A NEW SOLAR MINIMUM?
V.M. Velasco Herrera, W. Soon, D.R. Legates, August 1, 2021
In addition, our ML model forecasts a new phase of extended solar minima that began prior to Sunspot Cycle 24 (ca. 2008–2019) and will persist until Sunspot Cycle 27 (ca. 2050 or so).
Herrera, Soon and Legates in 2021 used a novel analysis and reached a similar conclusion, for cooling from ~2008 to ~2050.
