Limits to existing quantitative understanding of past, present and future changes to atmospheric carbon dioxide concentration

A presentation by Richard S. Courtney to the Climate Conference held In New York, on 2 to 4 March 2008 Synopsis This presentation demonstrates that it cannot be known what if any effect altering the anthropogenic emission of carbon dioxide (CO2) will have on the future atmospheric CO2 concentration. It is commonly assumed that the rise in atmospheric CO2 concentration …

Checking for model consistency in optimal fingerprinting: a comment

Abstract Allen and Tett (1999, herein AT99) introduced a Generalized Least Squares (GLS) regression methodology for decomposing patterns of climate change for attribution purposes and proposed the “Residual Consistency Test” (RCT) to check the GLS specification. Their methodology has been widely used and highly influential ever since, in part because subsequent authors have relied upon their claim that their GLS …

How much has the Sun influenced Northern Hemisphere temperature trends? An ongoing debate

Abstract In order to evaluate how much Total Solar Irradiance (TSI) has influenced Northern Hemisphere surface air temperature trends, it is important to have reliable estimates of both quantities. Sixteen different estimates of the changes in TSI since at least the 19th century were compiled from the literature. Half of these estimates are “low variability” and half are “high variability”. …

William Henry (Henry’s Law) 1803 Paper on Gas Absorption in Water

Experiment III. Experiments on the quantity of gases absorbed by water, at different temperatures, and under different pressures William Henry Published:01 January 1803 https://doi.org/10.1098/rstl.1803.0004 Abstract Though the solubility of an individual gas in water forms, generally, a part of its chemical history, yet this property has been overlooked, in the examination of several species of the class of aëriform substances. …

Comprehensive Analytical Study of the Greenhouse Effect of the Atmosphere

Peter Stallinga University of the Algarve, FCT-DEEI, Faro, Portugal Atmospheric and Climate Sciences, 2020, 10, 40-80 https://www.scirp.org/journal/acs ISSN Online: 2160-0422 ISSN Print: 2160-0414 Abstract Climate change is an important societal issue. Large effort in society is spent on addressing it. For adequate measures, it is important that the phenomenon of climate change is well understood, especially the effect of adding …

The Scientific Method in Contemporary (Climate) Research

P. Stallinga, Igor Khmelinskii Universidade do Algarve, Portugal Reprinted from ENERGY & ENVIRONMENT VOLUME 25 No. 1 2014 ABSTRACT In this work contemporary climate ideas are analyzed in the light of the Scientific Method developed through the ages. The conclusion is that science was not used in this subject. Download PDF This browser does not support PDFs. Please download the …

Analysis of Temporal Signals of Climate

Peter Stallinga, Igor Khmelinskii FCT and CEOT, University of the Algarve, Faro, Portugal ABSTRACT The dynamics of carbon dioxide in the atmosphere is analyzed and it is shown that the Pinatubo eruption in 1991 had a noticeable effect on these dynamics. The growth rate slowed down. Moreover, analyzing the year-on-year CO 2 growth data, we can see an anthropogenic footprint, …

The phase relation between atmospheric carbon dioxide and global temperature

Article in Global and Planetary Change · January 2013 DOI: 10.1016/j.gloplacha.2012.08.008 Ole Humlum, Kjell Stordahl, Jan-Erik Solheim Abstract Using data series on atmospheric carbon dioxide and global temperatures we investigate the phase relation (leads/lags) between these for the period January 1980 to December 2011. Ice cores show atmospheric CO2 variations to lag behind atmospheric temperature changes on a century to …

Signal Analysis of the Climate: Correlation, Delay and Feedback

Peter Stallinga University of the Algarve, Faro, Portugal Abstract One of the ingredients of anthropogenic global warming is the existence of a large correlation between carbon dioxide concentrations in the atmosphere and the temperature. In this work we analyze the original time-series data that led to the new wave of climate research and test the two hypotheses that might explain …
