Answer to Question 1

E

Answer to Question 2

Radiative forcing (climate forcing) describes the amount by which some perturbation causes the Earth's energy balance to deviate from zero. Examples include:
Positive radiative forcing: CO2, CH4, and tropospheric O3, all of which have anthropogenic sources.
Negative radiative forcing: stratospheric O3, and aerosols, both of which may be natural.
