Is climate change on other planets affected by similar cycles?

Click For Summary
SUMMARY

This discussion focuses on the influence of climatic cycles, such as El Niño and the Pacific Decadal Oscillation (PDO), on climate change both on Earth and other planets like Mars. El Niño, a phenomenon observed for over a century, correlates ocean warming with extreme weather patterns, affecting the jet stream every 3 to 4 years. Additionally, the Milankovitch cycles, which describe long-term variations in Earth's climate due to axial tilt and orbital eccentricity, have been documented on Mars, indicating that similar climatic patterns may exist across different planetary bodies.

PREREQUISITES
  • Understanding of El Niño and its historical context
  • Familiarity with the Pacific Decadal Oscillation (PDO)
  • Knowledge of Milankovitch cycles and their implications
  • Basic concepts of ocean-atmosphere interactions
NEXT STEPS
  • Research the historical impacts of El Niño on global weather patterns
  • Explore the mechanisms of the Pacific Decadal Oscillation (PDO)
  • Study the Milankovitch cycles in detail and their effects on Earth's climate
  • Investigate the climatic history of Mars in relation to Milankovitch cycles
USEFUL FOR

Climate scientists, meteorologists, planetary scientists, and anyone interested in understanding the interplay between climatic cycles and climate change across different planets.

I didn't expect that this year will be too hot here in the Philippines... D:

Welp... Here's an update :https://web.pagasa.dost.gov.ph/index.php/climate/climate-advisories

Is climate change taking effect here? I guess so.

Will somebody care for an ice cream? lol

El Niño has been around for over a hundred years, long before climate change was fashionable. It was first noticed by fisherman off the coast of
Peru when the waters would warm annually around late December near the birthday of The Child. Later, meteorologists noted a correlation between ocean warming and weather extremes due to oceanic-atmospheric interaction influencing the jet stream every 3 or 4 years resulting in weather extremes. Some scientists expect these extremes in both warm weather hurricanes and cold weather winter storms to increase in both intensity and frequency. I have no insight on this. But I sure coul use an ice cream, thanks!
 
From wikipedia
The Pacific Decadal Oscillation (PDO) is a robust, recurring pattern of ocean-atmosphere climate variability centered over the mid-latitude Pacific basin.

There is evidence that these kinds of cycles have existed in the far past: and there are climatic cycles that have very long periods like the Milankovitch cycle. These cycles have also been described for other planets - Example Mars:

Schorghofer, Norbert 2008. "Temperature response of Mars to Milankovitch cycles". Geophysical Research Letters 35 (18)

The idea here is that the axial tilt and the eccentricity of the a planet's orbit "conspire" to change input from the sun in polar regions over long period of time. The period of the Milankovitch cycle has some complex elements with a nice explanation:
