Solar Radiation

The sun is like a giant battery that powers everything on Earth. It sends heat and light through space to warm up the ground and the oceans. When the ground gets hot, it warms the air sitting on top of it. This heat makes the air start to move, which is how weather begins. Without the sun's energy, our planet would be a frozen, silent rock. It is the start of every breeze and every raindrop you feel.

You are a solar-powered being. Your energy is a loan from the star above. Every calorie you eat was sunlight first. You are walking, talking starlight.

Earth's energy budget is a complex equilibrium between incoming shortwave radiation and outgoing longwave radiation. Radiative forcing dictates the thermal structure of the troposphere. Connects to thermodynamics and photosynthesis — cosmic energy converted into biological and kinetic potential. Every weather system on Earth is ultimately powered by differential solar heating.

SOUND: The crackle of pavement cooling down after a hot summer day.

SMELL: Sun-baked pine needles or dry grass: the smell of stored energy.

TASTE: A vine-ripened tomato that turned sunbeams into sugar.

TOUCH: Radiating warmth on your skin during a noon walk.

SIGHT: Shimmering heat waves rising off a dark road.

BODY: The urge to squint and tilt your head toward the light: your body orienting to its power source.
