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 …

Cooling of Atmosphere Due to CO2 Emission

Cooling of Atmosphere Due to CO2 Emission

G. V. CHILINGAR, L. F. KHILYUK, and O. G. SOROKHTIN Introduction Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other greenhouse gases) absorb the infrared radiation from the Earth’s surface. …

Is the airborne fraction of anthropogenic CO 2 emissions increasing?

Wolfgang Knorr Received 18 August 2009; revised 21 September 2009; accepted 23 September 2009; published 7 November 2009. [ 1 ] Several recent studies have highlighted the possibility that the oceans and terrestrial ecosystems have started loosing part of their ability to sequester a large proportion of the anthropogenic CO2 emissions. This is an important claim, because so far only …

Global CO2 emissions from cement production

Robbie M. Andrew CICERO Center for International Climate Research, Oslo 0349, Norway Correspondence:Robbie M. Andrew (robbie.andrew@cicero.oslo.no) Published: 26 January 2018 Abstract.The global production of cement has grown very rapidly in recent years, and after fossil fuels andland-use change, it is the third-largest source of anthropogenic emissions of carbon dioxide. The required data for estimating emissions from global cement production are …

NO EXPERIMENTAL EVIDENCE FOR THE SIGNIFICANT ANTHROPOGENIC CLIMATE CHANGE

A new study by researchers at Turku University in Finland found that the human contribution to a rise of 0.1°C in global temperatures over the last century is just 0.01°C. The paper, titled ‘No experimental evidence for the significant anthropogenic climate change’ was published by Jyrki Kauppinen and Pekka Malmi. The study found that, “During the last hundred years the …

Human CO2 Emissions Have Little Effect on Atmospheric CO2

edberry.com Abstract The United Nations Intergovernmental Panel on Climate Change (IPCC) agrees human CO2 is only 5 percent and natural CO2 is 95 percent of the CO2 inflow into the atmosphere. The ratio of human to natural CO2 in the atmosphere must equal the ratio of the inflows. Yet IPCC claims human CO2 has caused all the rise in atmospheric …
