That is neat. TX for the share.
The Saharan dust really does gets around!

Fascinating!

Quite captivating - thanks Alan!

But it does make me wonder just how long the Sahara is going to last - has anyone calculated to the annual loss of sand?

[HansV]

Don't worry, the sand factories produce enough to compensate it.

But more seriously:

On average, 182 million tons of dust leave Africa each year, of which 27 million tons is deposited in the Amazon basin, according to data collected since CALIPSO launched in 2006.

It seems that greening, rather than sand loss, will spell the end of the Sahara, if that happens.

"Increased levels of carbon dioxide (CO2) have helped boost green foliage across the world's arid regions over the past 30 years through a process called CO2 fertilisation, according to CSIRO research."

Thank, Alan!

That is a great and fascinating article.

Your other link makes me wonder if increased CO2 in the atmosphere is a bad thing.

Indeed. But I won't start a rant about the topic in public!
