Ever wondered why Earth flips between freezing ice ages and warmer times? It’s all about the Milankovitch Cycles—three big, slow changes in our planet’s orbit and tilt that control how much sunlight hits the northern hemisphere. When the cycles line up just right, we get massive ice sheets and chilly temps. Right now, we should be cooling, but humans are throwing a curveball with greenhouse gases. Next ice age? It’s complicated! #Science #EarthScience #ClimateChange
