Is precession the cause of global warming?

Question

Ariana Acosta · Accepted Answer

It can't be.

If it were, the global temperature should follow a simple sine curve with a period of 26,000 years (assuming, for the sake of simplicity, no secondary effects). A thousand half-baked but sounding plausible theories will be offered by some people to explain some portion of the data. In all likelihood, people form opinions about what is true and then seek evidence to bolster those opinions. Whilst it is true that precession will have an effect due to the unequal irradiation of relative amounts of land and sea at differing inclinations, the effect is small (tiny?) compared to that caused by increasing (evidenced) rises in #CO_2# (and other greenhouse gases) concentration since the industrial revolution.

undefined No, precession is not the cause of global warming. Global warming is primarily attributed to the increase in greenhouse gas concentrations, such as carbon dioxide, methane, and water vapor, due to human activities. Precession refers to the gradual change in the orientation of Earth's rotational axis over time, which does not directly influence global temperature changes.
