Since 1984 humans have gushed forth 64% of our entire emissions from fossil fuels. (Fully 282,000 megatons of deplorable carbon “pollution”.) During this time, satellite images show that 24% of our beaches shrank, while 28% grew. Thus we can say that thanks to the carbon apocalypse there are 3,660 sq kms more global beaches now than there were thirty years ago. Yes. It’s that bad.
The encroachment of beaches would mean there is less ocean for fishes. Thankfully sea levels have risen too, so it looks like it will all work out.
This study also produced a handy map of where the sandiest beaches are. Clearly Africa wins (unless you prefer rocks and cliffs).
Presumbly the paradox of how seas can rise unprecedentedly fast at the same time as beaches are growing will be explained through global currents shifting ominously due to rising CO2 levels. Either that, or the paradox and the study will vanish into a subterranean library — like the deeper Asthenosphere Archive, where they will be converted to magma.
Seriously, though, this study appears to be the first to use automated detection with satellite images (nearly 2 million of them) to assess global beaches. Previous studies did things manually, or just interviewed people.
A few outlets have reported this, mainly with the predictable focus on the disappearing beaches and prophecies that “good beaches can’t last”.
