The scientist guest speaker compared it to a spinning top slowing down. I don't think he could compare it to a drunk uncle to a bunch of 5th graders, then again it was the 70s' LOL

[@RubbishFPS]

Yes we know there is a natural tilt that moves and effects general climate at a rate we can calculate. We can also tell when that rate is being sped up by non natural additions to the atmosphere that help magnify the suns rays as it passes through. Therefore causing a second form of climate change that we actually can slow down if we choose too. There is no reason to go harping on a natural cause that we cant control... Or do you just want there to be a scapegoat for something you dont want to deal with?

[@LuisLopez2]

I am from the Canary Islands. We call those dust storms "calima", although it is also used as a meteorological generalization..(Like the way the word "smog" is used in SoCal) My mother HATED those days. She was a obsessed with having the house spotless, hated dust.... Well, our building had - for some reason to this day unexplained - storm roll down shutters. When you closed them, the house was pretty sealed up. AND YET, this dust was so thin, it still someone made it in...very little, enough to drive my mother crazy. Silver-lining of Calima was.... it produced AWESOME surfing conditions, although visually weird. When dust blows from Sahara, it is carried by the Sirocco winds, which in our islands blow offshore on the North and East facing brakes. But in Calima days the Siroccos blow up high, so you get this wind-less conditions, with the sky glowing dark orange, water so glossy it looks like oil and the white water of the waves like a chocolate milkshake.

[@BlackChrRaw]

Question: Is the sand being replenished by other nature's phenomenons or is it slowly being emptied, thus changing the geographics in some way?

[@katherinegarlock2249]

Sand is basically eroded rock. So, as sand and dust is carried across the ocean, the rocks in the desert are eroded away, replenishing the sand that is lost. The rock comes from mostly compressed sediment (sedimentary rocks) since there are no volcanoes (igneous rock). Also, the amount of sand blown away and then eroded from stone is very small compared to the vast Sahara. Before there is any real impact, plate tectonics will have completely changed the geography of Africa, including the Sahara.

[@WilfredoWolganG]

Ever since I read an article a long time ago about what's happening to the Amazon rain forest when they cut it down and rip out all the vegetation, that what's left underneath is desert. Basically it said that because the vegetation was dense that it didn't allow much water to seep into the ground underneath it, hence the desert like soil underneath. I wondered if the same thing hadn't happened to the Sahara desert by humans. Also, since sand tends to kill most vegetation, I often wondered. if the desert had started out a lot smaller but had spread due to the wind blowing it further and further out into the African plains.

[@biffabacon6019]
