Signal Analysis of the Climate: Correlation, Delay and Feedback

Peter Stallinga University of the Algarve, Faro, Portugal Abstract One of the ingredients of anthropogenic global warming is the existence of a large correlation between carbon dioxide concentrations in the atmosphere and the temperature. In this work we analyze the original time-series data that led to the new wave of climate research and test the two hypotheses that might explain …

Scrutinizing the carbon cycle and CO 2 residence time in the atmosphere

Hermann Harde Helmut-Schmidt-University Hamburg, Experimental Physics and Materials Science, Holstenhofweg 85, 22043 Hamburg, Germany Received in revised form 11 February 2017 Abstract Climate scientists presume that the carbon cycle has come out of balance due to the increasing anthropogenic emissions from fossil fuel combustion and land use change. This is made responsible for the rapidly increasing atmospheric CO2 concentrations over …

Phase relation between global temperature and atmospheric carbon dioxide

December 2013 P. Stallinga and Igor Khmelinskii Universidade do Algarve, Portugal Abstract The primary ingredient of Anthropogenic Global Warming hypothesis is the assumption that atmospheric carbon dioxide variations are the cause for temperature variations. In this paper we discuss this assumption and analyze it on basis of bi-centenary measurements and using a relaxation model which causes phase shifts and delays. …

Climate skeptics are arguing with a straw man

Climate skeptics are arguing with a straw man

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 …

A New Law Of Climate Change

A New Law Of Climate Change

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 …

Heat waves and hot air

Heat waves and hot air

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 …
