The Relationship between Atmospheric Carbon Dioxide Concentration and Global Temperature for the Last 425 Million Years

MDPI climate W. Jackson Davis Received: 8 August 2017 / Revised: 15 September 2017 / Accepted: 22 September 2017 / Published: 29 September 2017 Abstract Assessing human impacts on climate and biodiversity requires an understanding of the relationship between the concentration of carbon dioxide (CO2) in the Earth’s atmosphere and global temperature (T). Here I explore this relationship empirically using comprehensive, recently-compiled databases of stable-isotope proxies from the Phanerozoic Eon (~540 million years before the present) and through complementary modeling using the atmospheric absorption/transmittance code MODTRAN. Atmospheric CO2 concentration is correlated weakly but negatively with linearly-detrended T proxies over the …

Of discount rates and candy-canes

“The time has come,” the Walrus said, “To talk of many things: Of shoes and ships and sealing-wax, Of cabbages and kings, And why the sea is boiling hot, And whether pigs have wings.” Lewis Carroll, Aliciae per speculum transitus WUWT By Christopher Monckton of Brenchley | January 11, 2019

CO2 is not causing (statistically relevant) global warming

Bud Bromley January 15, 2019 CO2, water, and CH4 (methane) and some other minor gases are so-called “greenhouse gases” because they absorb infrared energy.  However, be careful to avoid the common misunderstanding that the earth and its atmosphere behave like a garden greenhouse; that is not true.  Greenhouses are closed systems except to incoming energy.  Earth is an open system, open to receive energy, as well receive gases and other matter from space and also open to transmit energy, gases and matter back into space.  A greenhouse is a poor analogy for earth’s climate.

180 YEARS OF ATMOSPHERIC CO2 GAS ANALYSIS BY CHEMICAL METHODS

by Ernst-Georg Beck Reprinted from ENERGY & ENVIRONMENT VOLUME 18 No. 2 2007 ABSTRACT More than 90,000 accurate chemical analyses of CO2 in air since 1812 are summarised. The historic chemical data reveal that changes in CO2 track changes in temperature, and therefore climate in contrast to the simple, monotonically increasing CO2 trend depicted in the post-1990 literature on climate-change. Since 1812, the CO2 concentration in northern hemispheric air has fluctuated exhibiting three high level maxima around 1825, 1857 and 1942 the latter showing more than 400 ppm. Between 1857 and 1958, the Pettenkofer process was the standard analytical method …

The potency of carbon dioxide (CO2) as a greenhouse gas

By Antero Ollila September 2014 Abstract According to this study the commonly applied radiative forcing (RF) value of 3.7 Wm-2 for CO2 concentration of 560 ppm includes water feedback. The same value without water feedback is 2.16 Wm-2 which is 41.6 % smaller. Spectral analyses show that the contribution of CO2 in the greenhouse (GH) phenomenon is about 11 % and water’s strength in the present climate in comparison to CO2 is 15.2. The author has analyzed the value of the climate sensitivity (CS) and the climate sensitivity parameter () using three different calculation bases. These methods include energy balance …

The climate change bubble

Bud Bromley July 5, 2016 Dr. Judith Curry takes down the AAAS in the post at this link to her website. The American Association for the Advancement of Science (AAAS) attempts a power play on climate change but instead shoots itself in the foot. This is an example of the Iron Law of Bureaucracy. https://judithcurry.com/2016/07/04/climate-power-play-by-the-aaas-et-al/ The management of ACS is one of the signers of the AAAS propaganda letter. I was a member of the American Chemical Society (ACS) for many years. I was heavily involved with an ACS subgroup in gas chromatography in the 1970’s and early 1980’s. There …

The Club of Rome and beyond: How the socialist religion of environmentalism was born

The Rebel Tim Ball | February 20, 2016 The entire world needed the new paradigm of environmentalism. The problem is that a few grabbed it for a political agenda. They used it as a vehicle to take the moral high ground, to claim only they cared about the environment. They argue that everyone else was guilty of environmental destruction because of their avarice and wasteful ways. Environmentalism as a political agenda is pushed by extremely wealthy and powerful left wing people who made their money exploiting the environment. The psychology of that is beyond the realm of this discussion, but …

Press Release on Paper Showing the Invalidity of the EPA claim that CO2 is a pollutant

THS Research Files April, 2017 A just released peer reviewed Climate Science Research Report has proven that it is all but certain that EPA’s basic claim that CO2 is a pollutant is totally false. All research was done pro bono. This research failed to find that the steadily rising Atmospheric CO2 Concentrations have had a statistically significant impact on any of the 14 temperature data sets that were analyzed. The tropospheric and surface temperature data measurements that were analyzed were taken by many different entities using balloons, satellites, buoys and various land based techniques. Needless to say, if regardless of …

Invalidity of EPA’s CO2 Endangerment Finding

On the Existence of a “Tropical Hot Spot” & The Validity of EPA’s CO2Endangerment Finding Abridged Research Report Second Edition Dr. James P. Wallace III, Dr. John R. Christy, Dr. Joseph S. D’Aleo April 20, 2017 Excerpted summary of this peer-reviewed science: “The analysis results invalidate EPA’s CO2 Endangerment Finding, including the climate models that EPA has claimed can be relied upon for policy analysis purposes. Moreover, these research results clearly demonstrate that once the solar, volcanic and oceanic activity, that is, natural factor,impacts on temperature data are accounted for, there is no “record setting” warming to be concerned about.”
