I told the Pharaohs to quit driving their Hummers.
President Bush’s fault!

I thought this was a story of a gal who gave up the bottle and became sober. =)
“because if climate computer models don’t work for the past, they probably won’t work for the future.”
You mean climate is affected by things other than human activity? What a novel concept!
If Gore really believed in Global Warming, he’d buy the Sahara and wait. I mean how much could it cost?
Damn turbocharged camels!
(many know the joke, but I’ll bet nobody has pictures!)
Evolution in Your FaceLake Victoria, Africa's largest lake, is home to more than 300 species of cichlids. These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head. Seismic profiles and cores of the lake taken by a team headed by Thomas C. Johnson of the University of Minnesota, reveal that the lake dried up completely about 12,400 years ago. This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years!

FYI on your current efforts.
Pollen in a lake is heavily influenced by local effects due to the lake itself, around which the desert will accrue more slowly. AFIK, it is very difficult if not impossible to distinguish pollen generated locally from that thousands of miles away if only because "local varieties" migrate under changing conditions. So to say he knows what happened in Western Egypt for example, from analysis of samples taken from a lake bottom in Chad, is a massive stretch given the dispersion of the pollen at its sources and its confusion with other sources over an extended interval long ago.
Interesting story with some valuable data. I don't think the conclusion is likely to be supportable by the data.
Sahara dried out slowly, not abruptly: study
