Zdirad Žák: Question About 280 ppm CO2 Background Level
The late Ernst Georg Beck wrote a rather controversial but very interesting article titled “Reconstruction of Atmospheric CO2 Background Levels since 1826 from Direct Measurements near Ground “, published in this journal (Beck, 2022) that raised several comments, the most extensive being from Engelbeen (2023). However, he repeats the same objections (Engelbeen 2007) he had…
Anthony J. Sadar: Will Climate Change Crush Air Quality ?
Vol 4.1 Seventy-five years ago, in late 1948, 21 residents of Donora, Pennsylvania, US, and vicinity died from high concentrations of fumes emitted from the local heavy industry. This tragic event in Donora, a small town about twenty miles south of Pittsburgh, sparked the national air quality laws and regulations in the US. The notorious…
Hermann Harde: About Historical CO2-Data since 1826. The peak 1940-50 explained
SCC Volume 3.2. Recently a compilation of almost 100.000 historical data about chemical CO2 concentration measurements between 1826 and 1960 has been published as post mortem memorial edition of the late Ernst-Georg Beck. This compilation can give important insight in understanding natural CO2 emission processes, but it has been criticized, in particular a documented significant…
Jan-Erik Solheim: More Comments to Engelbeen’s Discussion Paper
SCC Volume 3.2. The late Ernst-Georg Beck wrote a monumental article titled “Reconstruction of Atmospheric CO2 Background Levels since 1826 from Direct Measurements near Ground “, published in this journal in 2022 (Beck, 2022). Beck‘s results are controversial, especially because his reconstruction showed a pronounced peak in atmospheric CO2 around 1940, which is contrary to…
Harald Yndestad: About Historical CO2 Levels. Discussion of Direct Measurements near Ground since 1828 by E.-G-Beck
SCC Volume 3.2. Ernst Georg Beck estimated a CO2 background time-series from 1826 to 1960. In a discussion from Ferdinand Engelbeen, he has a comment ha many of them are unsuited for background CO2-levels. The huge CO2 level around 1940 is physical impossible and contradicts other proxy´s.(Englebeen 2023). Beck collected approximately 100.000 data series from…
Ferdinand Engelbeen: About Historical CO2 Levels. Discussion of Direct Measurements near Ground since 1828 by E.-G-Beck
SCC Volume 3.2. Several comments can be made on the reconstruction of the historical CO2 data made by the late Ernst Beck (Beck, 2010, published in SCC 2022 [21]). While most chemical methods used were fairly accurate (+/- 10 ppmv), many places where was measured were completely unsuitable for “background” CO2 levels and in many…
Kees le Pair and Kees A. de Lange: On the Theory of the Earth’s Physical Parameters, Distributed in Space and Time
SCC Volume 2.3. Present day treatises dealing with weather and climate often use seemingly physical quantities, while they are in fact averages of such. Inserting these into formulas is physically not permitted. It leads to an assumption of the magnitude of the so-called ‘greenhouse effect’ several tens of K off. The often-used explanation of the…
Murry Salby and Hermann Harde: What Causes Increasing Greenhouse Gases? Summary of a Triology
SCC Volume 2.3. The Intergovernmental Panel on Climate Change (IPCC) classifies the human influence on ourclimate as extremely likely to be the main reason of global warming over the last decades. Particularly anthropogenic emissions of carbon compounds, with carbon dioxide (CO2) as the main culprit and methane (CH4) as a distant second, are made responsible…
Harald Yndestad: Publication of Ernst-Georg Beck’s Atmospheric CO2 Time series from 1826-1960
SCC Volume 2.2. On Christmas Day 2008, I received an e-mail from the German researcher Ernst-Georg Beck. He asked me to analyze an atmospheric CO2 time-series from 1820 to 1960. A CO2 time-series from 1820 was something special. Next day I went to work, analyzed the time-series, wrote a short note and e-mailed back a…
Bjørn Geirr Harsson and George Preiss: A Comment on Sea Level in the IPCC Climate Report
SCC Volume 1.1 Abstract When meteorologists with today’s great computing power can only predict the weather with some degree of certainty about 3 days into the future, how can we then expect climate scientists to predict the climate 100 years into the future? We have considered a single tide gauge at the Norwegian coast, Tregde.…
