Earth is getting dimmer — and the Northern Hemisphere is losing brightness faster than scientists expected. In this 2-minute Reel, see the shock stat and simple proof: satellite data shows a measurable drop in reflected sunlight (albedo) over recent decades, driven by land-use change, aerosols, and shifting cloud patterns. Quick visuals compare north vs. south brightness trends and explain why this matters for climate, agriculture, and weather. Perfect for viewers who want a fast, evidence-based
