INTRODUCTION

English translation pending.

CORE DEFINITION

The greenhouse effect is the warming of the surface because the atmosphere retains heat. A model of it describes the energy budget and temperature change of the Earth as a system. It is the canonical case of a reinforcing feedback loop: understanding how positive feedback can push a system out of balance provides an analogy for any self-reinforcing system dynamic.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use it as a feedback archetype: reach for it whenever a loop reinforces itself. - Read the energy budget: estimate surface temperature from the balance of incoming and outgoing radiation. - Separate natural from amplified: distinguish the natural effect from the human-enhanced one.

Shortwave solar radiation passes through the atmosphere and warms the surface, which re-radiates longwave infrared. Greenhouse gases absorb part of that outgoing radiation and re-emit it downward, so energy stays in the system longer than it otherwise would and the surface settles at a higher temperature.
