He assumed it was essentially a high - albedo desert prior to irrigation, and I don't think that's entirely accurate.
Also, if you want to compare the percent change in albedo of 0.134 (too high, but assume it correct for the moment) with a 1 % reduction, the latter would be 1 % of about 100 W / m ^ 2, not 1 % of 340 W / m ^ 2, and would yield a value of about 1 W / m ^ 2.
18.4wm - 2 higher assuming the same albedo means a radiative forcing of 3.23wm - 2, which is almost the forcing you get from doubling of CO2 or increasing solar output by 2 %.
The fact of the matter is that IPCC has relied in AR4 on models, which assume a strongly positive net feedback from clouds, while subsequent physical observations show that the primary impact of clouds with warming is increased albedo and higher SW reflection resulting in an overall negative cloud feedback.
