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 …

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 …

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 …

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 …

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 …

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 …

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 …

Cause cannot follow effect

Bud Bromley | January 23, 2016 Abstract: “The hypothesis that the increase in atmospheric carbon dioxide is related to observable changes in the climate is tested using modern methods of time-series analysis. The results confirm that average global temperature is increasing, and that temperature and atmospheric carbon dioxide are significantly correlated over the past thirty years. Changes in carbon dioxide …
