E non pensare a milioni di anni fa, infatti i pił recenti studi geologici stanno un po' rivisitando la storia geologica di quella catena montuosa che potrebbe essersi sollevata quasi completamente nello spazio di 100 mila anni.
In effetti, forse anche meno...
Taller mountains a result of global warming
Heavy glaciers cause the Earth's crust to flex inward slightly. When glaciers disappear, the crust springs back and the overlaying mountains are thrust skyward, albeit slowly.
The European Alps have been growing since the end of the last little Ice Age in 1850 when glaciers began shrinking as temperatures warmed, but the rate of uplift has accelerated in recent decades because global warming has sped up the rate of glacier melt, the researchers say.
