English composition on weather change, 500-600 words! ! ! thank you

Weather is a collection of all phenomena in a specific atmosphere at a specific time. It also includes interaction with the hydrosphere. This term usually refers to the activities of these phenomena in a short period of time (hours or days), as opposed to the word climate, which refers to the average atmospheric conditions over a long period of time. When used without limitation, "weather" is understood as the weather of the earth.

I hope to adopt O (∩ _ ∩) O. Thank you.
