Climate Sensitivity Calculator — Formula
## Equilibrium Climate Sensitivity
Climate sensitivity tells us how much the global average temperature will eventually rise for a given radiative forcing.
### Formula
**Delta T = Delta F x lambda**
Where Delta F is radiative forcing (W/m²) and lambda is the climate sensitivity parameter (°C per W/m²). The IPCC best estimate for doubling CO2 (3.7 W/m²) is about 3°C, giving lambda around 0.8.

Exemplo Resolvido
A doubling of CO2 produces 3.7 W/m² of forcing with a sensitivity of 0.8 °C per W/m².
- Temperature change = 3.7 x 0.8 = 2.96 °C
- In Fahrenheit: 2.96 x 1.8 = 5.33 °F
