If the Earth were tilted at 33.5 degrees instead of the current 23.5 degrees, the impact on regional temperatures would be significant. The increased tilt would lead to more extreme seasonal variations in temperature.
During summer, regions closer to the poles would experience much hotter temperatures due to the increased angle of the sun’s rays. Conversely, during winter, these same regions would experience much colder temperatures as the sun’s rays would be at a lower angle, reducing the amount of solar energy received.
This increased tilt would result in more pronounced temperature differences between seasons. The equator would still remain relatively stable in terms of temperature, but the mid-latitudes and polar regions would see more extreme weather patterns. This could lead to longer and hotter summers, as well as longer and colder winters.
In summary, a 33.5-degree tilt would cause more extreme temperature variations across the globe, particularly in the higher latitudes, leading to more intense seasonal changes.
