. Re-radiation of heat occurs

. Less re-emitted heat

. More heath escapes into space

Hence the greenhouse effect refers to return of 80% of heat radiated by Earth.

While during Human Enhanced Greenhouse effect :

. Solar radiation reaches earth

. Re-radiation of heat occurs

. More re-emitted heat

. Less heat escapes into space

Hence the enhanced greenhouse effect refers to return of more than 80% of heat radiated by Earth .
