More dust in the air presumably means that there are more nuclei on which water molecules can condense to form liquid water.Water vapour is a greenhouse gas so can the current trend in global warming be attributed to less dust in the air than usual resulting in more water vapour and higher temperatures? And why would there be less dust given that winds are getting stronger? Are the deserts becoming more sticky - have manmade chemicals glued desert particulates together making them heavier and more difficult for the wind to move? Or have the lightest sand particles been moved by the passage of millennia leaving only the heavier ones on the surface of the deserts? This wouldn't explain why the glacial-interglacial cycle exists however because we would expect a constant rise in average global temperature over the 1.5 million years that the cycle has existed, based on this theory. Australia has a large desert area.
Does dust from Australia's deserts cause the cooler years in the south pacific between El Nino events?
