📖 How to Use This Simulation

Step 1: Adjust the CO₂ level slider to set initial conditions.

Step 2: Click "Step 1 Year" to advance one year at a time, or "Run 50 Years" to watch the feedback loop in action.

Step 3: Watch how temperature rise causes ice melt, which lowers albedo (reflectivity), which causes more warming — a positive feedback loop!

Key concept: This simulation shows why Arctic ice loss can accelerate beyond what initial warming would cause alone.

💡 What's Happening?

Start the simulation to see the ice-albedo feedback in action. As temperature rises, ice melts. Dark ocean water absorbs more sunlight than white ice (lower albedo), causing more warming, which melts more ice... and the cycle continues!

Key Concept: This is why climate scientists are concerned about Arctic ice — once melting begins, it can accelerate beyond what the initial warming would cause alone. This is called a "tipping point" effect.
