Document Summary

The global energy balance, climate forcing"s and feedbacks. Albedo: the al(cid:271)edo is the f(cid:396)a(cid:272)tio(cid:374) of i(cid:374)(cid:272)o(cid:373)i(cid:374)g (cid:396)adiatio(cid:374) that is (cid:396)e e(cid:272)ted (cid:271)(cid:455) a(cid:374) o(cid:271)je(cid:272)t. The global distribution of energy: the incoming solar radiation and the outgoing infrared radiation are not uniformly distributed a(cid:272)(cid:396)oss the ea(cid:396)th"s su(cid:396)fa(cid:272)e! Forcing"s and feedbacks in the climate system: key forcing"s in the climate system, natural. Incoming solar energy: earth orbit variations, volcanoes and emission of aerosols (e. g. , dust) Solar processes: anthropogenic, emission of greenhouse gases, emission of aerosols from human activity. 1 w/ m2): this variations are associated with the sunspot cycle, effects on climate of these variations are detectable but small. Measurements are shown from ice cores (symbols with different colours for different studies) and atmospheric samples (red lines): the corresponding radiative forcing"s are shown on the right hand axes of the large panels. However, as they are constantly emitted, there are lots of them around at any given time.
