Summary

Story summary

A study in *Nature* indicates that Earth's seasons are becoming increasingly out of sync, affecting biodiversity.
Researchers examined 20 years of satellite imagery, pinpointing seasonal asynchrony hotspots in Mediterranean and tropical mountain regions.
This asynchrony could cause genetic divergence in species due to mismatched reproductive cycles.
The findings emphasize the importance of these regions for ecological and evolutionary studies.
Improved methods for observing global seasonal patterns are necessary.
