The Winter Gatekeeper Hypothesis (VII). A summary plus Q&A

by J. Vinos and A. May, Sep 22, 2022 in ClimateEtc.

“On the other hand, I think I can safely say that nobody understands climate change.” J. Vinós, paraphrasing Richard Feynman’s words about quantum mechanics.

7.1 Introduction

This plain-language summary has been written at the request of some readers of our series of articles on the Winter Gatekeeper hypothesis:

Climate is extremely complex, and people, including scientists, have a natural tendency to look for simple explanations. The Occam’s Razor principle is a good first approach but climate change cannot have a simple answer. Over the past seven years, one of the authors of this series (JV) has been laboriously reading many thousands of scientific articles and analyzing hundreds of climate datasets trying to understand how Earth’s climate changes naturally. This is a first step to understanding the human impact on climate change. The outcome of this work is the book Climate of the Past, Present and Future.” It is a graduate-student level academic book that discusses many controversial issues about natural climate change over the past 800,000 years. In this book, a new hypothesis on natural climate change is presented. It relates changes in the strength of the meridional (poleward) transport of energy with climatic changes that have taken place, both in the past and recently.

How Can The Globe Be Warming When Most Of The Southern Hemisphere Isn’t?

by K. Richard, Sep 22, 2022 in NoTricksZone

New research continues to document non-warming and even “robust cooling” trends for entire regions of the Southern Hemisphere in recent decades.

Land surface temperature data compilations from the Southern Hemisphere (South America, Southwestern Andes, Tasmania, New Zealand, Australia) indicate that any warming during the 20th century occurred before 1980, with no obvious net warming since (Rezsöhazy et al., 2022).

Sea surface temperature data from the Southeastern Indian Ocean, Tasman Sea, and Great Barrier Reef region indicate no net warming since 1982 (Chapman et al., 2022).

A 2021 study reported a profound cooling trend for most of Antarctica in recent decades, with amplitudes of -2.8°C for East Antarctica and -1.68°C for West Antarctica during 1979-2018.
