Grok 3 beta et al.: A Critical Reassessment of the Anthropogenic CO₂-Global Warming Hypothesis
The Intergovernmental Panel on Climate Change (IPCC) attributes observed climate variability primarily to anthropogenic CO₂ emissions, asserting that these emissions have driven approximately 1 Wm⁻² of net radiative forcing since 1750, resulting in a global temperature rise of 0.8-1.1°C. This conclusion relies heavily on adjusted datasets and outputs from global climate models (GCMs) within the…
Roth: About the Origin of CO2 in the Atmosphere.
A study published by the CO2 Coalition claims that the rise in atmospheric CO2 concentration is manmade. This claim is examined here and rejected. There are two fundamental shortcomings in the study: It is based on an inappropriate model, that is far from reality, and it ignores that the atmosphere is an open system. In…
Ato: Pitfalls in Global Warming and Climate Change Research
Recent global warming and climate change studies frequently assume that the rise in atmospheric CO2 is entirely due to human emissions. In particular, the assumption is based on a figure of CO2 concentration of 280 ppm at the end of the pre-industrial period. However, this assumption reveals itself to be contradicted by an examination of…
W. A. van Wijngaarden and W. Happer: Radiation Transport in Clouds
We briefly review the dominant role of clouds in Earth’s climate. The earliest observational studies of heat transfer through Earth’s atmosphere, for example, those of John Leslie around 1800, showed that clouds have a large effect on radiative heat transfer from Earth’s surface to space. Greenhouse gases also affect heat transfer, but much less than…
Aaslid: Climate Science versus Politics
Starting with a critical look at the IPCC science, from the excellent First Assessment Report in 1990 and downhill to the latest Sixth Assessment Report with its claim that we have had no natural climate change since the pre-industrial era, we also take a closer look at the 2010 IAC critical evaluation of IPCC, as…
Cederlöf: The Temperature Fluctuations in Uppsala has Natural Causes
The temperature record from Uppsala in Sweden starts already in 1722. This is one of the world’s longest temperature series available. A great job has been made to adjust and homogenize this data to be consistent over time, measurement locations and changed equipment. However, during the 20th and 21th century this temperature series has diverged…
Solheim: SCC – the three first years
The scientific journal Science of Climate Change was initiated by the Climate Realists in Norway in the summer of 2020. The first issue appeared in August 2021 and the journal has now existed in 3 years and produced 11 issues. The objective of this journal was and is, to publish – different to many other…
Hansen: The Danish Energy Transition
Denmark has set ambitious goals for CO₂-emission reductions and wishes to play the role of front-runner in the World. However, in reality the results are not so impressive and the transition is running into serious difficulties. Continue reading …
Brekkestø: The Rise and Fall of Civilizations in a Climate Perspective
Civilizations flourished during the warm periods, such as the Bronze Age, the Roman era, and the medieval times, when weather conditions were relatively stable with more precipitation in the tropic and subtropical areas. Civilizations experienced decline or succumbed during the cold periods, such as 1 200 to 500 BC, 300 to 700 AD and the…
Nordin: The Role of Science in Climate Politics
I gave a short introduction to the climate conference in Mölndal 26-27 October 2024. The theme of the conference was “Science and Politics” so I picked up a couple of basic philosophical words of wisdom for this occasion. The first sentence comes from the 18th century philosopher David Hume with the following logic statement:¬ (Is…
