Maybe you folks don’t hear about it, but for the last few years us folks here in S Florida have the Saharan Dust report on our evening weather shows every night. Fine red dust is blown off North Africa and across the Atlantic, sometimes reaching the States as far west as Texas and as far north as the Carolinas. On particularly bad days, sometimes you can even see it as a fine
dust showing up on shiny surfaces, like on your car’s paint job in the morning. There’s a positive side to this, the dust apparently makes it harder for hurricanes to form in the eastern Atlantic, so during times of bad dust, we get much fewer big tropical storms. Anything that can tamp those down is welcome! Then again, this might be affecting some of the ocean’s heat transfer mechanisms…I also have heard some scientists theorize iron in the dust contributes to some of the toxic algae blooms and red tide events we’ve been plagued with lately (iron is a trace nutrient that is otherwise lacking in these waters).
Drought in N Africa and in the Sahel region seems to be causing the problem–global warming again.
