The Greenhouse Effect Blackbodies emit a broad spectrum centered around λ max = 2897/T λ max (sun) = λ max (5800K) = 0.50 µm λ max (earth) = λ max (300K) = 10 µm

The Greenhouse Effect
Blackbodies emit a broad spectrum centered around λmax = 2897/T
λmax(sun) = λmax(5800K) = 0.50 µm λmax(earth) = λmax(300K) = 10 µm

Ok, so that’s the Greenhouse Effect.
What’s global warming?
This is global warming
Greenhouse Gases: CO2
CO2 emissions from fossil fuel combustion
Greenhouse Gases: Methane
Greenhouse Gases: Water Vapor
Positive feedback
