The limits of carbon dioxide’s influence on world temperature

Posted on February 29, 2012 by Dr. Ed

by Bryce Johnson

Foreword

Proponents of anthropogenic global warming (AGW) hold that mankind causes the increase in atmospheric carbon dioxide (CO2) by burning fossil fuels and that without urgent measures to reduce its increase it will cause a runaway temperature increase within a few decades that will have unacceptably severe consequences to mankind. This article addresses the limits of the ability of fossil-fuel consumption to increase atmospheric CO2 level and on its associated temperature increase.  Primary findings are summarized in the following paragraph: Continue reading →

Two Roots of IPCC’s Errors

Posted on December 7, 2011 by Dr. Ed

by Kyoji Kimoto　(e-mail kyoji@mirane.co.jp)

1. Model studies by Manabe et al.

Climate sensitivity is 0.5K from the global energy budget of the earth, and it is 0.8K from the data analysis of Pinatubo eruption. However, IPCC claims that most probable value is 3K with the range of 2.0-4.5K. The following two roots exist for IPCC’s overestimation of climate sensitivity:

(1) Cess’s mathematical error in 1976 being followed by many researchers (see the previous post IPCC’s overestimation of climate sensitivity.)

(2) Overestimation by 1D RCM study in [Manabe et al. 1964/67](see Figure1) Continue reading →

IPCC’s overestimation of climate sensitivity

Posted on November 18, 2011 by Dr. Ed

1. Climate sensitivity from the energy budget of the earth

Figure1 is a diagram of global energy budget of the earth based on the latest study [Trenberth et al., 2009]. From the figure, natural greenhouse energy is calculated as follows to produce natural greenhouse effect of 34K.

Natural greenhouse energy:

Eb-Es = 333W/m2-78W/m2=255W/m2     (1)

Then, climate sensitivity factor is obtained as follows including climate feedbacks.

Climate sensitivity factor:

34K/255W/m2 = 0.13K/(W/m2)            (2) Continue reading →

More carbon dioxide cools, not warms, the earth

Determination of the Total Emissivity of a Mixture of Gases Containing 5% of Water Vapor and 0.039% of Carbon Dioxide at Overlapping Absorption Bands.

by Nasif S. Nahle, from the PDF (see general description here)

Professor and Director of Scientific Research Division at Biology Cabinet Mexico

Abstract

This assessment is a review of the common AGW argument on carbon dioxide increasing the potential of water vapor for absorbing and emitting IR radiation as a consequence of the overlapping absorption/emission spectral bands. I have determined the total emissivity of a mixture of gases containing 5% water vapor and 0.039% carbon dioxide in all spectral bands where their absorptivities-emissivities overlap. The result of these calculations is carbon dioxide attenuates the total absorptivity-emissivity of water vapor, working like a coolant, not a warmer of the atmosphere and the surface.

Does the Tropopause Limit Carbon Dioxide Heat Trapping?

Posted on June 21, 2011 by Dr. Ed

by Richard J. Petschauer, June 10, 2011, Revised June 29, 2011

[This revision adds non-standard atmospheric lapse rates to the calculations.]

Background

Basic greenhouse theory shows that as the concentration of CO2 increases, a thinner atmosphere is required to allow the heat to radiate to outer space. This causes the typical emission altitude to increase that usually implies a lower temperature, thus causing a drop of the heat loss to space, forcing the atmosphere to warm and finally the surface below.

G12. Carbon Dioxide: An Innocent Bystander in Climate Change

Posted on April 4, 2011 by Dr. Ed

by Bryce Johnson

Abstract

An atmospheric radiation transport code, SpectralCalc™ (1) has been used to predict carbon dioxide’s contribution to earth heating.  The code predicts that doubling atmospheric CO2 raises its temperature by only 0.22 degrees C.  This temperature rise is very much lower than “conventional” predictions which indicate at least a 1 C rise for doubling (2). The code shows that increasing CO2 by a factor of eight would trigger a 0.86 C rise while an increase of 0.72 C would be manifest by only a 30 percent increase in water vapor. Continue reading →

How much CO2 really contributes to global warming? Spectroscopic studies and modeling of the influence of H2O, CO2 and CH4 on our climate

by Hermann Harde, Helmut-Schmidt-Universität Hamburg, Germany
(harde@hsu-hh.de)

Based on the actual HITRAN’ 2008 database [1] detailed spectroscopic studies on the absorbance of the greenhouse gases water, carbon dioxide and methane in the atmosphere are presented. The objective of these investigations was to examine and to quantify with these newly available data the influence of these gases on our climate. Continue reading →

G9. The Greenhouse Effect

Posted on March 4, 2011 by Dr. Ed

by Vincent Gray, NZ Climate Truth Newsletter No 262

The greenhouse effect is caused by absorption of infra red radiation from the earth by trace gases in the earth’s atmosphere. A greenhouse confines only a small part of the atmosphere, so the trace gas absorption is negligible. Continue reading →

G10. Improved Simple Climate Sensitivity Model

Posted on February 26, 2011 by Dr. Ed

by Richard J. Petschauer (February 24, 2011)

1.  Summary of the Present Simple Model and Its Limitations

The present simple climate model, used by most climate scientists to estimate climate sensitivity, is based on maintaining energy balance between the net solar incoming shortwave solar radiation and the outgoing longwave radiation from the planet. Increased CO2 reduces the outgoing radiation in the upper atmosphere where most of it originates, causing the temperature in the region of the radiation to increase until energy balance is maintained.  While this seems adequate for CO2, it ignores the required balance also of the atmosphere and the surface where feedbacks originate.

Ferenc Miskolczi’s Saturated Greenhouse Effect Theory

by Miklos Zagoni, SPPI, December 18, 2009

The Earth’s atmosphere differs in essence from that of Venus and Mars. Our atmosphere is not totally cloud-covered, as is Venus: globally, about 40% of the sky is always clear. Also we have huge ocean surfaces that serve as a practically unlimited reservoir of water vapor for the air. Continue reading →

Climate sceptics offer a peace deal. Well, no it wasn’t quite like that. But in Lisbon, Portugal, last week, I joined a group of 28 climate scientists, bloggers and professional contrarians who spent three days discussing how to encourage reconciliation in the increasing fractious debate about the science of climate change.
