On the tilt of the Earth's polar axis (climat): Some 'impressionist' remarks

TL;DR

This paper reflects on the concept of climate by analyzing long-term stable maps of physical parameters and questions whether ground temperature is a consequence of climate rather than a separate parameter.

Contribution

It offers an impressionistic analysis of climate parameters over time and proposes reconsidering ground temperature's role in climate theory, inspired by historical hypotheses.

Findings

Stable maps of climate parameters over time

Questioning ground temperature as a separate climate parameter

Suggesting temperature as a consequence of climate

Abstract

In this lengthy letter, we wanted to discuss the concept of climate based on definitions established for over a century and direct observations that we have been collecting for more than a century as well. To do this, we present and discuss the remarkably stable maps over time of the various physical parameters that make up the climate corpus: solar temperature, atmospheric pressure, winds, precipitation, temperature anomalies. This impressionistic tableau that we are gradually sketching as our reflection unfolds leads us to the following proposition: What if, as Laplace first proposed in 1799 and later Milankovi\{'}c in 1920, ground temperature were merely a consequence of climate and not a separate parameter of climate in its own right?
