Understanding Global Warming

Scientists and a Summary

Global warming calls for ingenuity, innovation and entrepreneurship. In order to attract venture capital, it is necessary to understand the task, its opportunities and risks. With an extent from the Arctic Ocean to the Baltic Sea, there are in the Kingdom of Denmark special interests and opportunities to examine the ongoing changes. Researchers are mentioned in random order.

Figure 1. Thanks to Danish Willi Dansgaard, we know a lot about the temperature of the past. Here analyzed by Ole Humlum. The green curve models the cyclical factors found. The superimposed historical events help to recognize the time axis. The warm periods found in our northern provinces are mirrored in Southern Denmark.

Willi Dansgaard.

In the 1950s, Willi Dansgaard investigated the relationship between the mean annual temperature and the δ18O (oxygen isotope) of precipitation at many locations worldwide. He was the first paleo climatologist to demonstrate that measurements of δ18O and δD (deuterium) in accumulated glacier ice could be used as an indicator of past climate. He was also the first scientist to extract paleoclimatic information from the Greenlandic Camp Century ice core – hyperlink. In 1974, Willi Dansgaard predicted that the post-war declining temperatures would soon reach a valley followed by a short-term warming.

 

Ole Humlum.

Thanks to Ole Humlum, who succeeded Willi Dansgaard at the Disco station, we know a lot about the cyclical factors that affected the globe in the past. Together with Jan-Erik Solheim and Kjel Stordahl, he published the article "Identifying natural contributions to late Holocene climate change" in Global and Planetary Change in 2011 - hyperlink. Figure 1 is taken from this article. Ole Humlum is a Danish professor emeritus of physical geography at the University of Oslo, Department of Geosciences and adjunct professor of physical geography at the University Center in Svalbard. His academic focus includes glacial and periglacial geomorphology and climatology. Ole Humlum is the author of “State of the Climate 2018” – hyperlink.


Valentina Zarkova.

The proxy temperatures of the GISP2 ice core (fig. 1) show warm periods that coincide with the oscillation of the baseline of the solar magnetic field. A super-grand cycle is 1950 ± 95 years polarity wise peaking every half cycle as explained by Prof. Valentina Zharkova, Northumbria University and supports the analysis made by Ole Humlum. The baseline magnitude become slowly increasing towards its maximum at 2600 AD to be followed by its decrease and minimum at 3700 AD. This trend is anticipated to continue in the next six centuries that can lead to a further natural increase of the terrestrial temperature by more than 2.5 oC by 2600 AD – hyperlink. [The article has been retracted and the author has issued the following minor correction - hyperlink] Zharkova correctly predicted the weakness of solar cycle 24 and she predicts the next solar cycle will be the lowest in 200 years - a Grand Solar Minimum like the Dalton Minimum.

Harald Yndestad

    Harald Yndestad (dr.philos and professor at Norwegian University of Science and Technology (NTNU) in Aalesund), a Norwegian professor in cybernetics, has proposed a climate theory based on long-term astronomical cycles. He argues that the Moon and the major planets, especially Jupiter and Saturn, play a key role in driving Earth's climate over centuries. According to Yndestad, gravitational forces from these celestial bodies affect oceanic and atmospheric circulation through subtle changes in the Earth's rotation and the lunar nodal cycle, which spans 18.6 years. These variations can amplify or dampen climate patterns like the North Atlantic Oscillation and influence long-term temperature trends.

Yndestad’s ideas align closely with the work of Valentina Zharkova, known for her model of solar activity based on the Sun’s internal magnetic waves. Zharkova predicts significant climate impacts due to solar minima, such as the one expected in the 21st century. Both researchers challenge the dominant anthropogenic climate change narrative, emphasizing natural cycles driven by celestial mechanics.

Henrik Svensmark

Thanks to Henrik Svensmark, we know the natural forcing of the sun’s magnetic field and its effect on cosmic rays and cloud formation. He is a Danish physicist and professor in the Division of Solar System Physics at the Danish National Space Institute in Copenhagen - hyperlink.

Peter Stallinga

Prof. Peter Stallinga was born in the Netherlands, holds a postdoc at the University of Aarhus, Physics and Astronomy and now a professorship at Universidade do Algarve, Portugal. He has published carbon dioxide studies - hyperlink and operates a Climate page on his domain stalling.org – hyperlink.

Xinxing Yang

Xinxing Yang is associated with The Research Center of Climate Change and Impact, Chinese Research Academy of Environmental Sciences, Beijing. Xinxing Yang is completely in line with Peter Stallinga and both question the importance of CO2 as a significant climate driver as explained in “Carbon Dioxide Is Not the Chief Culprit of Global Warming” - hyperlink

Karin Margarita Frei

Karin Margarita Frei, Research Professor of Archaeometry at the Danish National Museum and her "Tales of Bronze Age Women" has convinced us that the era of the Egtved girl in the Minoan Warm Period has been as warm as our current Modern Warm Period – hyperlink.

Catherine A. Jessen,

Catherine A. Jessen is also associated with the Danish National Museum. Catherine has provided stomatal-based reconstruction of atmospheric carbon dioxide for the above mentioned era of the Egtved Girl – hyperlink.

Dorte Haubjerg Søgaard

New research by Dorte Haubjerg Søgaard, Greenland Climate Research Centre, Greenland Institute of Natural Resources, University of Greenland has shown that also sea ice removes CO2 from the atmosphere. Dorte Søgaard has several important publications on the subject - hyperlink.


US Scientists

Almost all the above scientists belong to our part of the world. However, we have also been following scientists farther away to better understand the global aspect. Several of them - Will Happer, Richard Lindzen, Roy Spencer and others - are according to The Washington Times advisers to the president - hyperlink.


Summary


Earth's climate has naturally shifted between warm and cold periods in recurring cycles. Notable warm periods include:

  • The Minoan Warm Period (peaked around 1500 BC)

  • The Roman Warm Period (peaked around 250 AD)

  • The Medieval Warm Period (peaked around 1000 AD)

  • The Modern Warm Period (beginning now, with the peak still ahead)

These warm phases, spaced roughly 1000–1100 years apart, suggest a connection to long-term solar cycles. Valentina Zharkova describes a Grand Solar Cycle of about 2200 years, which may explain the timing and recurrence of these climatic fluctuations. This perspective supports the idea that natural celestial cycles play a dominant role in shaping Earth’s climate over millennia.



Planetary periods for Saturn (blue), Uranus (green), Neptune (grey) and total solar radiation (TSI) index (red) for the years 2000-2100 AD. NASA started satellite-based measurement of solar radiation in 1979. In 2014, NASA researchers were able to publish a continuous data series for total solar radiation (TSI) for the years 1700-2013. The TSI index is negative in the period 2025-2072. In the cooling period forward to the year 2072, there is a computed Fimbulwinter minimum in the year 2064. Kilde The Climate Clock- Link

  Understanding Global Warming Temperature is getting more pleasant Figure 1.   Hadley Centre Central England Temperature (HadCET) dataset + DMI+ NOAH The CET dataset represents the world’s longest continuous instrumental temperature record. Danish temperature data have been superimposed for comparison. The earliest Danish measurements were taken from the top of the Round Tower in Copenhagen and subsequently converted to a national average, with an estimated uncertainty of ±0.5 °C. Also shown are global temperature values from NOAA (National Oceanic and Atmospheric Administration), adjusted by adding 13.7 °C (the IPCC’s assumed preindustrial average) plus global anomaly for 1980 +0.51 °C, resulting in an approximate absolute temperature of 14.2 °C....

Henrys Law

  Understanding Global Warming Henrys Law Figure 1. IPCC Carbon Cycle AR5. Simplified schematic of the global carbon cycle. Numbers represent carbon mass and exchange fluxes in Gt (Pg) carbon per year – hyperlink . The enclosed part [our highlighting] shows a chain of circles connecting the atmospheric carbon with that of the sea - quite to the sediment on the ocean floor. A total upward flux of 207,1 GtC is indicated. According to Henry’s law , a balance must be maintained between the concentration of CO₂ in the atmosphere and in the ocean’s surface layer. As chemical and biological processes remove CO₂ from surface waters and transport it to deeper layers, space is created for additional CO₂ uptake at the surface. However, this downward transport introduces a delay in the system’s overall response. Consequently, only an amount of CO₂ roughly equivalent to half of the fossil fuel emissions is absorbed by the oceans on an ongoing basis. An amount corresponding to the r...

Egtved Girl

  Understanding Global Warming The Egtved Girl and her time   Karin Margarita Frei of The National Museum of Denmark, Copenhagen has convincingly told us about the Egtved girl and her age as a warm and fruitful period - also warmer than today, hence the interest in the Minoan Warm Period - hyperlink .  That the climate was really warmer at that time can be deduced from the fact that in the Bronze Age, millet was grown in southern Scandinavia. Millet is grown today in tropical and subtropical areas. No remains of stables from that time have been found. Apparently the cattle were kept out all year. So probably the climate in the middle of the Bronze Age was about 2 degrees warmer than in the present. 40,000 Bronze Age mounds have been registered. There have been many more, but especially on the islands they have been plowed down. The large number, testifies to an unbelievably rich time, but also to a signifi...
