Jens Olaf Pepke Pedersen: The Global Carbon Cycle in an Earth System model
Earth system models are useful tools for understanding past global changes and for projecting future global change.

SCC Volume 3.4 The carbon cycle is of great importance to understand the influence of anthropogenic emissions on the atmospheric CO2 concentration, and thus, to classify the impact of these emissions on global warming. Different models have been developed, which…
SCC Volume 3.4 According to the IPCC’s popular narrative, the man-made emission of CO2 accumulates in the atmosphere. A fixed portion stays there, while the rest ends up in land and sea reservoirs However, the carbon cycle is not a…
Volume 3.4 Carbon cycle models referred to by the IPCC are all-encompassing and they apply several sub-models designed for special tasks like CO2 exchange with plants. The objective of this presenta-tion is to analyze critically the IPCC’s carbon cycle model…
SCC Volume 3.4 How can we understand climate change – when it requires us to understand several natural science connections? This article shows how I solved the teaching for my six grandchildren, between 10 and 18 years old, because they…
The current increase in atmospheric CO2 is predominantly caused by human emissions. All other explanations violate the mass conservation law.
SCC Volume 3.4 This paper addresses several issues concerning Milankovitch Theory and its relationship to paleoclimate data over the last 800,000 years. The insolation is described physically as a time-dependent wave. It is analogous to an AM radio wave. Its…
SCC Volume 3.4 To recognize the current climate change in the right perspective, it is vitally important to know climate in the past. The knowledge of past climate, however, has been largely missing. There is the very widespread and convulsive…
SCC Volume 3.4 During the summer of 2023 media announced that the Gulf Stream should disappear already in 2025. A colder climate was expected in Northern Europe. This was based on a paper by two Danish researchers who had discovered…
SCC Volume 3.4 A wavelet spectrum analysis of TSI data series from 1000 AD and 1700A D computed a Maunder-Dalton type next deep sola minimum at the year 2049 (Yndestad and Solheim 2017). New investigations have revealed that The Little…
Volume 3.4 The Greenhouse Effect was simulated in a laboratory setup, consisting of a heated ground area and two chambers, one filled with air and one filled with air or CO2. While heating the gas, the temperature and IR radiation…
SCC Volume 2.1. The organization Climate Realists of Norway was started in 2009 and part of our activity is topresent facts about climate and climate change in public meetings. It soon became evident that many of our members wanted to…
SCC Volume 2.1. The past 150 years show that affordable and reliable energy is key to financing basic needs, such as food, health, sanitation, housing, electricity, and education. The past 150 years also show that more CO2 is beneficial for…
SCC Volume 2.1. 1. IntroductionThe replication crisis is a phenomenon widely accepted in major institutions of science (Ioannidis, 2005, 2014, Baker 2016). Roughly half of peer reviewed scientific literature is probably flawed or totally wrong. There are almost certainly problems…
SCC Volume 2.1. Due to a resource-efficient food production – famine will be a thing of the past in our affluent society. Famine due to climate change is simply not true. We can easily feed everyone – even if we…
SCC Volume 2.1. Since the start of this century, polar bears have been an icon for all that’s worrisome about human-caused global warming. Polar bears are the most-used example to try and convince the public that burning fossil fuels already…
