Il collasso dell’AMOC diventa un rischio reale

  Il collasso dell’AMOC diventa un rischio reale Quando un governo considera una corrente oceanica un problema di sicurezza nazionale, significa che qualcosa è cambiato davvero. L’Islanda ha ufficialmente classificato il possibile collasso dell’AMOC — la grande circolazione che porta calore dall’Atlantico ai mari del Nord — come minaccia esistenziale. Una decisione rara. E un segnale forte per l’Europa. Perché l’AMOC è così importante L’AMOC funziona come un gigantesco nastro trasportatore: acqua calda dai tropici sale verso nord, si raffredda, affonda e torna indietro in profondità. È questo flusso a rendere gli inverni europei sorprendentemente miti per la latitudine. Il problema è la velocità del cambiamento. L’acqua dolce proveniente dallo scioglimento della Groenlandia sta “diluendo” l’Atlantico del Nord, disturbando il meccanismo che permette all’acqua salata di affondare. Se l’affondamento rallenta, l’intero circuito si indebolisce. Se si ferma, collassa. Gli scienzia...

Police raid Sydney house after ‘mystery of bitcoin creator is solved’

Over a dozen police officers entered the home of Craig Steven Wright who Wired magazine said was the real identity of Satoshi Nakamoto, the figure who released the first bitcoin code back in 2009.
Now, there appears to be another lead on the anonymous founder.

The raids by police in Australia came a few hours after a website online published articles that said investigations had shown that Wright, an academic and entrepreneur was mostly like the secretive creator of bitcoin.
Police have raided the Sydney home of a man named as the likely creator of cryptocurrency bitcoin.
“Either Wright invented Bitcoin, or he’s a brilliant hoaxer who very badly wants us to believe he did”, saidWired, which based its conclusions on a series of leaked emails and archived web documents.
“The Australian Federal Police can confirm it has conducted search warrants to assist the Australian Taxation Office at a residence in Gordon, Sydney”, police said in a statement, without confirming it belonged to Mr Wright.
“Despite a massive trove of evidence, we still can’t say with absolute certainty that the mystery is solved”.
On Gizmodo, reporters Sam Biddle and Andy Cush write of their inquiry into Wright and Dave Kleiman, a computer forensics expert who died in 2013, that they “obtained confirmation from on-the-record sources that Wright claimed on at least two occasions that he and Kleiman were both involved in the creation of Bitcoin”.
It was reported by Newsweek in March last year that Satoshi Nakamoto is not a pseudonym and the man behind Bitcoin is a 64-year-old Japanese American.
Nakamoto vehemently denied any involvement with Bitcoin in a letter provided by Nakamoto’s lawyer Ethan Kirschner to Felix Salmon, then a financial blogger at Reuters.
