ClimatExam by Dr. Antero Ollila The Earth receives 99.97% of its energy from the Sun. The global warming impact caused by greenhouse gases is calculated in such a way that it corresponds to the change in solar radiation at the top of the atmosphere and is called Radiative Forcing (RF). If the amount of solar energy changes, then the change in radiation power multiplied by the climate sensitivity parameter directly gives global warming effect. If the change had occurred in solar activity in a short period of time, it would be widely reported. When a change has occurred due to …

By Bud Bromley | July 19, 2021 The problem that global warming skeptics have had for years is they are arguing a point where their opponents – that is the proponents of AGW or human-caused global warming – are using estimates of human CO2 emissions. But skeptics in rebuttal have no measurements of global human CO2 emission, obviously because it is buried in the noise of CO2 fluxes which are at least 10 times larger.  Skeptics are arguing with a straw man on a yellow brick road. AGW proponents, as they tend to do, proposed a hypothesis which they believe cannot be validated …

By Michael Kile | July 11, 2021 What a treat. I had not been so flummoxed since reading Alan Sokal’s  scholarly hoax over two decades ago: “Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity”. That the latest World Weather Attribution (WWA) post, Rapid attribution analysis of the extraordinary heatwave on the Pacific Coast of the US and Canada June 2021, has twenty-one contributors from prestigious research groups around the world gave it even more piquancy. The WWA post, alas, is neither hoax nor parody, but the real deal: a collaboration – in record time -“to assess to what extent human-induced climate change made this …

by Judith Curry | July 15, 2021 Heat waves are the new polar bears, stoking alarm about climate change.  Climate scientists addressing this in the media are using misleading and/or inadequate approaches.  How should we approach assessing whether and how much manmade global warming has contributed to recent record breaking  temperatures?  Read on for some outside-the-box thinking on this. Much has been written in recent weeks on the record-breaking heat wave in the US Northwest and Canada There have been four categories of scientific contributions to answering this question, that have appeared in the media, blog posts and publications: I.  …

By Paul Dorian | July 14, 2021   Photograph of a dust storm captured in the Texas Panhandle during March 1936. When the drought and dust storms showed no signs of letting up, many people abandoned their land. The Dust Bowl exodus was the largest migration in American history. By 1940, 2.5 million people had moved out of the Plains states of which 200,000 moved to California. Courtesy PBS Overview One of the most widespread and destructive heat waves ever recorded in the US took place in the summer of 1936 which fell right in the middle of arguably the …

FOCUS Magazine: Australian Academy of technological sciences and engineering August, 2008 Should we try harder to understand the causes of natural climate change instead of assuming present climate change is man-made? By Lance Endersbee endersbee@optusnet.com.au In the past, sea temperatures were obtained from measurements by passing ships in the sea lanes of the world. It is only in the past three decades that more accurate data on sea surface temperatures has become available. The analysis of this recent data by the author shows that: the oceans regulate the composition of the atmosphere; the influence on climate of human-generated carbon dioxide …

No Tricks Zone By P Gosselin on 15. June 2021 Statistical data alterations, huge data gaps and dissenting experts are among the problems plaguing climate science, new Japanese CIGS working paper highlights.  In November 2019, the Canon Institute for Global Studies (CIGS) released a working paper noting that natural factors are also very much at work when it comes to climate change. Now CIGS has added another. New working paper A new working paper has been released, in Japanese – authored by KiryeNet – and it reports that climate change goes well beyond one trace gas running the climate show …

Introduction This document is intended to provide the newcomer to headspace sampling with a concise summary of the theory and principles of this exciting technique. Enough information is included here for the user to understand the basic concepts and relationships in HS sampling to apply during method development and interpretation of data. Although emphasis is given to the PerkinElmer TurboMatrix™ HS systems, the document also covers alternative systems so that it should be useful to all potential users of HS systems. It is not intended to be a comprehensive review of the subject and the reader is directed to an …
