Discussion Overview

The discussion explores the hypothetical scenario of Earth having a thicker atmosphere at 2 bar pressure. Participants consider the implications for daily and seasonal temperature variations, weather patterns, and the potential effects on life and human development in such an environment.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • Some participants speculate on how a thicker atmosphere might affect temperature and weather, suggesting that doubling the atmospheric pressure could lead to significant changes.
  • Others express skepticism about the speculative nature of the question, arguing that it may not align with the forum's purpose.
  • One participant notes that doubling the pressure would imply a doubling of air density, prompting considerations of how this change could affect energy and momentum in meteorological models.
  • There is mention of modeling similar effects on other planets, indicating that some participants draw parallels with extraterrestrial atmospheres.

Areas of Agreement / Disagreement

Participants generally disagree on the appropriateness of the speculative nature of the question, with some engaging in hypothetical modeling while others challenge the validity of such speculation.

Contextual Notes

The discussion lacks consensus on the implications of a thicker atmosphere, and assumptions regarding the applicability of meteorological models to Earth are not fully explored.

What would Earth be like if the atmosphere was twice as thick at 2 bar? How would it affect the daily and seasonal variation in temperature and weather? How would it have affected life in general and if we grew up in this environment how would we be different?

You are asking for nothing but speculation and wild guesses, that is not what this forum is for.

Double the pressure would imply roughly a doubling of the air density, so one can take the basic meterological equations/models and increase the air density. If one has a fluid, and one doubles the density, what does that do to the energy and momentum?

People do model such affects, e.g., particularly with respect to other planets.

Unfortunately he is asking for speculation about earth. :smile: This was supposed to have been closed, my mouse is dying and doing weird things.
