"Temperature trends" refers to the direction and pattern in which the average temperature of a specific area or the entire planet is changing over a certain period of time. It helps us understand if the temperature is getting hotter, colder, or remaining relatively constant, which can be important for evaluating climate change or exploring weather patterns.
