What is Earth's Energy Balance?

Earth's energy balance is the equilibrium between incoming solar radiation and outgoing terrestrial radiation. When this balance is maintained, Earth's climate remains stable. When it's disrupted, global temperatures change, driving climate patterns and weather systems.

Why Energy Balance Matters

☀️

Solar Energy Input

Earth receives energy from the sun at a rate of about 240 watts per square meter, averaged across the planet.

🌡️

Temperature Control

The balance between incoming and outgoing energy determines Earth's average surface temperature.

⚖️

Climate Stability

A balanced energy budget maintains stable climate conditions. Imbalances cause warming or cooling.

📊

Human Impact

Human activities are disrupting this balance, trapping more heat and causing rapid climate change.

💡 Try this: Increase greenhouse gases to see how it creates a positive energy imbalance (warming). Then increase albedo to see how reflectivity affects the balance.
