(e) Estimated temperature response to anthropogenic forcing, consisting of a warming component from greenhouse gases, and a cooling component from most aerosols.
The top three curves show total anthropogenic forcing assuming central values for all components other than indirect aerosol forcing.
``... snow pack has decreased and been observed to melt earlier in the calendar year... the observed changes in the hydrological components... can be explained well by anthropogenic forcing (green house gases and aerosols) alone.»
IPCC tells us that 93 % of the past forcing was from anthropogenic components and that all other anthropogenic components beside CO2 (aerosols, other GHGHs, etc.) cancelled one another out so that total anthropogenic forcing = CO2 forcing.
(e) Estimated temperature response to anthropogenic forcing, consisting of a warming component from greenhouse gases, and a cooling component from most aerosols.
IPCC AR4 WG1 tells us that the all anthropogenic forcing components except CO2 (aerosols, other GHGs, land use changes, other changes in surface albedo, etc.) have essentially cancelled one another out, so we can use the estimated radiative forcing for CO2 (1.66 W / m ^ 2) to equate with total net anthropogenic forcing (1.6 W / m ^ 2).
The inset in Figure 2d shows the individual greenhouse gases, tropospheric aerosols and the land surface plus snow albedo components that combine to give the net anthropogenic forcing.
Figure 10.4 of AR5, reproduced as Figure 2 below, shows in panel (b) estimated scaling factors for three forcing components: natural (blue bars), GHG (green bars) and «other anthropogenic» — largely aerosols, ozone and land use change (yellow bars).
On the other hand, the anthropogenic component and the aerosol forcing, which were neglected in our study, may induce additional predictable trends.
IPCC tells us that all anthropogenic forcing components other than CO2 (aerosols, other GHGs, etc.) cancelled one another out over this period, so the forcing from CO2 = total anthropogenic forcing ~ 1.6 W / m ^ 2.
So when IPCC tells me that all anthropogenic forcing components other than CO2 (aerosols, albedo, land use, other GHGs, etc.) essentially cancel one another out, I have to accept this as likely to be correct.
This tells us that over this period all other anthropogenic forcing components (aerosols, other GHGs, land use changes, surface albedo changes, etc.) essentially cancelled one another out, so we can ignore your statement «we suspect that aerosols caused cooling», as this is already compensated for by other anthropogenic warming beside CO2.
