L'Everest, la montagna più alta del mondo, ha guadagnato 86 centimetri di altezza rispetto alla misurazione svolta negli anni Cinquanta dai ricercatori indiani. La sua nuova altezza ufficiale ora è di 8'848,86 metri. È stata determinata dalle spedizioni congiunte condotte dalla Cina e dal Nepal. L'annuncio è stato dato martedì durante la videoconferenza da Wang Yi, il ministro degli Esteri di Pechino.
I cinesi verso la cima dell'Everest per verificarne precisamente l'altezza
RSI/OrtellRO 18.05.2020, 17:52
Per determinare l'altitudine, le squadre dei due paesi hanno scalato la montagna posizionandovi vari strumenti di misura. La squadra nepalese è salita in vetta nel 2019, mentre quella cinese quest'anno.
Per arrivare al nuovo valore, oltre ai dati forniti da GPS e vari strumenti, sono state impiegate anche le misurazioni della gravità in prossimità della vetta e calcoli basati su un modello computerizzato.
