Chapter 4, Problem 48Q

Interpretation Introduction

Interpretation: When Arrhenius first theorized the role of atmospheric greenhouses, he calculated that doubling the concentration of $C{O}_2$ would result in an increase of $\text{5-6}{}^{\text{o}}\text{C}$ in the average global temperature. It should be explained that how far off was he from the current IPCC modeling.

Concept Introduction:

• • According to IPCC- International Panel on Climate Change, radiative forcing is the radiactive forcing of the surface – troposphere system due to the perturbation in or the introduction of an agent is the change in net irradiance at the tropopause after allowing for stratospheric tempertures to readjust to radiative equilibrium, but with surface and tropospheric temperatures and state held fixed at the unperturbed values.
• • Global warming is a serious environmental issue, in which there is an increase in the overall temperature of the earth by various factors.
• • Greenhouse gases are the gases that trap heat in the atmosphere
