Exactly. The weather is not a stationary time series. The moments of the probability distribution are not time invariant. ________________________________ From: NANOG <nanog-bounces+rod.beck=unitedcablecompany.com@nanog.org> on behalf of Rich Kulawiec <rsk@gsp.org> Sent: Monday, February 22, 2021 6:18 PM To: nanog@nanog.org <nanog@nanog.org> Subject: Re: Texas internet connectivity declining due to blackouts On Tue, Feb 16, 2021 at 12:23:22PM +0000, Bret Clark wrote:
Texas doesn't generally experience this type of extreme cold.
That was then; this is now. As scientist Jeff Masters put it most of a decade ago: The atmosphere I grew up with no longer exists. My new motto with regards to the weather is, "expect the unprecedented." In the years since he's said that we've seen a number of unprecedented events: Sandy, Harvey, California wildfires, last year's midwest derecho, and so on. This event in Texas is just another one; there will be more; they'll get worse. We should probably get ready for that. ---rsk
