@lyse@lyse.isobeef.org Oh dear, going on a hike in that heat sounds a bit like suicide to me. 😅

If I read this correctly (and that’s a big “if”), than the Sahara sand stuff isn’t new: https://www.dwd.de/EN/research/observing_atmosphere/composition_atmosphere/aerosol/cont_nav/saharan_dust_node.html

@movq@www.uninformativ.de You’re right, that was silly. But what do you gonna do? I could have picked bike, well.

At least it’s been a thing since July 1997. :-D I wouldn’t be surprised if this goes on for thousands of years. The German Wikipedia article on that matter doesn’t explicitly say anything about the time scale, but reading it my assertion corroborates. There is a recorded event in the year 1901.

@movq@www.uninformativ.de Being lazy is what I did today. :-)

That’s a bitter, but true résumé. I’m pretty sure that I first heard of the Saharan air layer only a few years ago. I would be very surprised if my knowledge is more than a decade old. This could have been a big enough topic to be covered in geography lessons, but it doesn’t ring a bell. Just like with everything, there is always something “new” to learn.
