5G ha effetti anche sul sistema di previsione del tempo !




Il grande capo del National Ocean Service americano ha lanciato un allarme secondo cui le frequenze 5G  (24 GHz) vanno a disturbare il sistema di rilevamento dati utili per le previsioni del tempo.  Parla addirittura di un deterioramento della qualità di previsione che annullerebbe i miglioramenti avuti negli ultimi 30 anni !
L'impatto immaginato è innazitutto per i tanti americani che vivono sulle coste e che contano sul sistema di allerta uragani (che fa parte delle loro certezze ).

5G Networks Could Throw Weather Forecasting Into Chaos

From Wired
Excerpt:
If you had a choice between a better, faster cell phone signal and an accurate weather forecast, which would you pick? That’s the question facing federal officials as they decide whether to auction off more of the wireless spectrum or heed meteorologists who say that such a move could throw US weather forecasting into chaos.
On Capitol Hill Thursday, NOAA’s acting chief, Neil Jacobs, said that interference from 5G wireless phones could reduce the accuracy of forecasts by 30 percent. That’s equivalent, he said, to the quality of weather predictions four decades ago. “If you look back in time to see when our forecast scale was roughly 30 percent less than today, it was 1980,” Jacobs told the House Subcommittee on the Environment.
That reduction would give coastal residents two or three fewer days to prepare for a hurricane, and it could lead to incorrect predictions of the storms’ final path to land, Jacobs said. “This is really important,” he told ranking committee member Frank Lucas (R-Oklahoma)
In March, the FCC began auctioning off its 24-gigahertz frequency band to wireless carriers, despite the objections of scientists at NOAA, NASA, and the American Meteorological Society. This week, Senators Ron Wyden (D-Oregon) and Maria Cantwell (D-Washington) wrote  to FCC chair Ajit Pai requesting the commission stop companies from using the 24-GHz band until a solution is found, and to delay any more of the auction…SNIP
