How would the alteration of Earth's tilt by a few degrees impact global climate patterns and ecosystems?

Question

1)it would only affect the polar regions, leaving equatorial climates unchanged
2)it would have no significant effect, as climate is primarily determined by ocean currents
3)it would lead to more extreme seasonal variations, affecting plant growth and animal migration patterns
4)it would result in a uniform climate across the globe, eliminating seasonal changes

Answer 1

The correct answer is:

3) it would lead to more extreme seasonal variations, affecting plant growth and animal migration patterns.

Altering Earth's axial tilt, even by a few degrees, would significantly impact the distribution of sunlight across the planet, especially throughout the changing seasons. This change would increase the contrast between seasons, resulting in hotter summers and colder winters in some regions. Such shifts could disrupt ecosystems, impacting plant growth cycles, and altering animal migration patterns as species adapt to the new climatic conditions.
