Radiation physics constraints on global warming: CO2 increase has little effect

D. G. Rancourt University of Toronto June 2011 Abstract I describe the basic physics of planetary radiation balance and surface temperature, using the simplest model possible that is sufficiently realistic for correct evaluations of predicted surface temperature response sensitivities to the key Earth parameters. The model is constrained by satellite absolute integrated intensity and spectroscopic measurements and the known longwave absorption cross section of CO2 gas. I show the predicted Earth temperature for zero atmospheric resonant absorption of longwave radiation (no greenhouse effect in the otherwise identical atmosphere) to be-46 o C, not-19 o C as often wrongly stated. Also, …

World Scientists’ Warning of a Climate Emergency

William J Ripple, Christopher Wolf, Thomas M Newsome, Phoebe Barnard, William R Moomaw Author Notes BioScience, biz088, https://doi.org/10.1093/biosci/biz088 Published: 05 November 2019 A correction has been published: BioScience, biz152, https://doi.org/10.1093/biosci/biz152 Download PDF Viewpoint Scientists have a moral obligation to clearly warn humanity of any catastrophic threat and to “tell it like it is.” On the basis of this obligation and the graphical indicators presented below, we declare, with more than 11,000 scientist signatories from around the world, clearly and unequivocally that planet Earth is facing a climate emergency. Exactly 40 years ago, scientists from 50 nations met at the First …

Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale

V. V. Zharkova, S. J. Shepherd, S. I. Zharkov & E. Popova Scientific Reports volume 9, Article number: 9197 (2019) Abstract Recently discovered long-term oscillations of the solar background magnetic field associated with double dynamo waves generated in inner and outer layers of the Sun indicate that the solar activity is heading in the next three decades (2019–2055) to a Modern grand minimum similar to Maunder one. On the other hand, a reconstruction of solar total irradiance suggests that since the Maunder minimum there is an increase in the cycle-averaged total solar irradiance (TSI) by a value of about 1–1.5 …

Understand Climate Science Before Making Climate Policy

George C. Marshall Institute Roger W. Cohen, May 14, 2010 One of the most remarkable dynamics in the global warming debate is the response to the question: “Tell me, what is the case for significant anthropogenic global warming?” The responses tend to fall into three categories: One is appeal to authority: “All scientific societies agree that carbon dioxide emissions are causing (fill in the blanks)” Second is the “It doesn’t matter” response: “Even if the science is wrong, it is still important to do something about it” (that “something” is always big and expensive). I’m going to call this the …

A Short Summary of Soon, Connolly and Connolly

By Andy May Soon, Connolly and Connolly (2015) is an excellent paper (pay walled, for the authors preprint, go here) that casts some doubt about two critical IPCC AR5 statements, quoted below: The IPCC, 2013 report page 16: “Equilibrium climate sensitivity is likely in the range 1.5°C to 4.5°C (high confidence), extremely unlikely less than 1°C (high confidence), and very unlikely greater than 6°C (medium confidence).” Page 17: “It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and …

Re-evaluating the role of solar variability on Northern Hemisphere temperature trends since the 19th century

Willie Soon, Ronan Connolly, Michael Connolly Abstract Debate over what influence (if any) solar variability has had on surface air temperature trends since the 19th century has been controversial. In this paper, we consider two factors which may have contributed to this controversy: Several different solar variability datasets exist. While each of these datasets is constructed on plausible grounds, they often imply contradictory estimates for the trends in solar activity since the 19th century. Although attempts have been made to account for non-climatic biases in previous estimates of surface airtemperature trends, recent research by two of the authors has shown …

Climate Change, Tropospheric Warming, and Stratospheric Cooling

Jamal Munshi Sonoma State University Date Written: August 25, 2018 Abstract Climate models predict that rising atmospheric CO2 will simultaneously warm the troposphere and cool the stratosphere. This combination of tropospheric warming and stratospheric cooling is found in the observational data over a period of rising atmospheric CO2. Although strong correlations between these time series are found in the source data, the correlations do not survive into the detrended series at annual or five-year time scales. The absence of detrended correlation implies that the correlations seen in the source data derive from shared trends and not from responsiveness at annual …

Study: ‘Back radiation’ not a component of climate change

Principia Scientific Published on September 2, 2019 Written by John O’Sullivan 2019 study published in Geophysical Research Letters (GRL) affirms Downward Longwave Radiation (DLR) “cannot be considered an independent component of the surface energy budget.” The conclusion affirms the science of researchers at Principia Scientific International. The paper, ‘Does Surface Temperature Respond to or Determine Downwelling Longwave Radiation?‘ was published on February 19, 2019. The Abstract reads: Abstract Downward longwave radiation (DLR) is often assumed to be an independent forcing on the surface energy budget in analyses of Arctic warming and land‐atmosphere interaction. We use radiative kernels to show that …
