When
aerosols from human activities such as industrial plant and vehicle
emissions are added to the system, the energy
budget has to deal with the increase.
Agree with Mr. Richards (31) that a «
budget» for 1.5 C has already been exceeded — due e.g. to «thermal response factor» (Hansen), present
aerosol dimming, further
emissions during energy transition, unfolding climate feedbacks and planetary response to actual total carbon dioxide eguivalent.
