The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (VI). Meridional transport is the main climate change driver

by Javier Vinós & Andy May “No philosopher has been able with his own strength to lift this veil stretched by nature over all the first principles of things. Men argue, nature acts.” Voltaire (1764) For those that prefer it, Christian Freuer has translated this post into German here. 6.1 Introduction Climate is a thermodynamic processContinue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (VI).

Are fossil-fuel CO2 emissions good or bad?

By Andy May This is the transcript, with minor edits to get it into blog post format, of my keynote speech to the AAPG Division of Professional Affairs, at the second International Meeting for Applied Geoscience and Energy Convention in the George R. Brown Convention Center in Houston on August 30, 2022. In the greatContinue reading “Are fossil-fuel CO2 emissions good or bad?“

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (V). A role for the sun in climate change

by Javier Vinós & Andy May “Once you start doubting, just like you’re supposed to doubt. You ask me if the science is true and we say ‘No, no, we don’t know what’s true, we’re trying to find out, everything is possibly wrong’ … When you doubt and ask it gets a little harder toContinue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (V).

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (IV). The unexplained/ignored climate shift of 1997

by Javier Vinós & Andy May “These shifts are associated with significant changes in global temperature trend and in ENSO variability. The latest such event is known as the great climate shift of the 1970s.” Anastasios A. Tsonis, Kyle Swanson & Sergey Kravtsov (2007) For those that prefer it, Christian Freuer has translated this postContinue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (IV).

Overview of the Koonin-Dessler Debate

By Andy May The SOHO Forum Debate began at 5:30PM (Central Time) on August 15, 2022 in the New York Sheen Center, as I announced here. Koonin won the Oxford Style debate since 25% of the in-person and online audience shifted to his view that the debate question: “Climate science compels us to make largeContinue reading “Overview of the Koonin-Dessler Debate”

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (III). Meridional transport, the most fundamental climate variable

by Javier Vinós & Andy May “The atmospheric heat transport on Earth from the Equator to the poles is largely carried out by the mid-latitude storms. However, there is no satisfactory theory to describe this fundamental feature of the Earth’s climate.” Leon Barry, George C. Craig & John Thuburn (2002) For those that prefer it,Continue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (III). Meridional transport, the most fundamental climate variable“

The Koonin-Dessler Debate

By Andy May Update: You may be able to watch the debate on Youtube around August 24th, the link that worked for a short time has been taken down. The debate I announced here between Steve Koonin and Andy Dessler took place Monday August 15th, it was very educational and illuminating. I will try andContinue reading “The Koonin-Dessler Debate”

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (II). Solar activity unexplained/ignored effects on climate

by Javier Vinós & Andy May “The complicated pattern of sun-weather relationships undoubtedly needs much further clarification, but progress in this field will be hindered if the view prevails that such relationships should not be taken seriously simply because the mechanisms involved in explaining them are not yet identified.” Joe W. King (1975) For thoseContinue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (II). Solar activity unexplained/ignored effects on climate“

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (I). The search for a solar signal

by Javier Vinós & Andy May “Probably no subfield of meteorology has had as much effort devoted to it as the effects of solar variability on weather and climate. And none has had as little to show for the research labor.” Helmut E. Landsberg (1982) For those that prefer it, Christian Freuer has translated thisContinue reading “The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (I). The search for a solar signal”
