The Limits of Atmospheric Carbon Dioxide Effects and Control

Abstract

The interactions of the fossil-fuel source of carbon dioxide with the atmosphere as well as in the total biosphere are analyzed. The time dependence of resulting carbon levels and temperatures in all components of the biosphere are determined under a full range of possible insertion and depletion rates to and from the atmosphere as carbon dioxide. The three most significant findings follow:

  1. There is no rate at which such man-produced carbon can be inserted into the atmosphere that will result in a harmful temperature rise before the total inventory of carbon in the world’s fossil-fuel reserves has been depleted, at which point CO2 and temperature increases cease.
  1. Man’s efforts at reducing atmospheric carbon are ineffective. The same natural forces that inhibit increases in the atmosphere also inhibit decreases.  The total carbon content of the remainder of the biosphere and its exchange rate with the atmosphere overwhelm whatever man can do to alter the atmospheric level;
  1. The natural temperature feedback from carbon dioxide increase in the atmosphere is predominantly negative (acting to diminish further increase). There is no possibility of an unstoppable runaway reaction.

The obvious conclusions from these findings are that there is no need to reduce man-made carbon dioxide in the atmosphere and such an attempted reduction would be completely futile even if there were a need. Continue reading →

Why Al Gore’s Comments to Bill O’Reilly at Fox News Are Wrong

by Chuck Wiese, Meteorologist, Weatherwise, Incorporated, Portland, Oregon
(PDF here. Earlier version on WUWT here.)

From a meteorologist’s perspective, nothing is worse than to see atmospheric science trashed by the likes of Al Gore, who is a self-proclaimed expert in this area, but has had no formal training from any accredited university and constantly makes incorrect and unprovable assertions about “human caused” climate change.

The latest revelation came on February 2, 2011, when Mr. Gore eagerly answered a questioning of the accuracy of Gore’s past claims about climate from Bill O’Reilly from the Fox News Channel since much of the central and east coast of the US have had a cold and snowy winter. Gore told O’Reilly that the snowstorms of this winter were part of the pattern of changing climate expected by scientists and result from the warming earth air masses with more moisture were running into a patch of cold air. Gore claimed:

“These warmer air masses (which Gore claims result from human carbon emissions that create atmospheric CO2) act like a sponge to moisture and soak it up until they hit a patch of cold air.”

Gore then claims that this “extra moisture” contained in the warmer air causes more intense precipitation and thus heavier snowfall, and is all consistent with a warming earth. Continue reading →

Conclusions

According to the simple-minded or ‘classic’ view of the greenhouse effect the global average greenhouse temperature change may be estimated by the direct application of the Beer-Lambert law moderated by local or regional scale weather phenomena (R. Pierrehumbert, A. Lacis, R. Spencer, R. Lindzen, A. P. Smith, H. deBruin, J. Abraham et al., J. Hansen et al.,and many others)*. This is not true.

The greenhouse effect is a global scale radiative phenomenon and cannot be discussed without the explicit quantitative understanding of the global characteristics of the IR atmospheric absorption and its governing physical principles.

The dynamics of the greenhouse effect depend on the dynamics of the absorbed solar radiation and the space-time distribution of the atmospheric humidity. The global distribution of the IR optical thickness is fundamentally stochastic. The instantaneous effective values are governed by the turbulent mixing of H2O in the air and the global (meridional) redistribution of the thermal energy resulted from the general (atmospheric and oceanic) circulation.

Mexican Professor shows Greenhouse Effect does not exist

by Ed Berry

Here is a simple physics experiment any high school student can do to show the greenhouse effect does not exist. Step-by-step instructions are given in Professor Nasif Nahle’s report, downloadable on Climate Clash.

Professor Nahle of Monterrey, Mexico, backed by a team of international scientists, recreated a famous 1909 experiment by Professor Robert W. Wood at John Hopkins University. Nahle’s results confirm Wood was correct and confirm that the greenhouse effect cannot cause global warming. Continue reading →

G12. Carbon Dioxide: An Innocent Bystander in Climate Change

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 →

G10. Improved Simple Climate Sensitivity Model

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 →

Foreword

The SpectralCalc™ Code

In a recent publication (1) Richard J. Petschauer utilized the SpectralCalc™ computer code (2) to demonstrate that carbon dioxide is but a “bit player” in earth warming by greenhouse gases (ghg’s). The code is extremely detailed and sophisticated, containing all the needed atmospheric and IR absorption parameters needed for an accurate description of “greenhouse” heating throughout the entire atmosphere.  Continue reading →

Carbon Heat Trapping: Merely a Bit Player in Global Warming

by Richard J. Petschauer, Senior Member IEEE, Private Publication

Abstract

New calculations show that doubling of carbon dioxide (CO2) will increase average global temperature by only about 1F (degrees Fahrenheit) or 0.55C (degrees Centigrade), much less than the range of 2C to 4.5C estimated by the United Nations International Panel on Climate Change (IPCC). These new calculations are based on NASA supported spectral calculations available on the Internet relating to greenhouse gases. Continue reading →

G2. Greenhouse Gas Effect

By Al Tekhasski, Rev.0.4 11/26/2010

1. Introduction

Greenhouse gas effect (GHGE) is an effect on a scale of a planet. It should not be confused nor conflated with glass panes or polymer films over a bed of plants. It does not matter how bad the name is; it is what it is. We can call it “greenfruugh effect,” or “greencheese effect,” the name does not make any difference. In addition, the existence of greenhouse gas effect must be differentiated from how its magnitude actually varies (or not) with change in GH gases concentration, which is sometimes dubbed as “enhanced greenhouse effect” and is the cornerstone of AGW theory.
