They are talking about a cold snap with similar regional coverage on a similar date, they are not saying cold snaps only occur once every 250 yrs.
[[They are talking about a cold snap with similar regional coverage on a similar date,]]
Do they not watch weather reports? Every couple of years arctic air drops into the US- blankets the upper parts of the country- This is not unusual or rare- You can see the cold snaps descend o n the US from the maps they show- the whole upper part of the country gets blanketed- We have relatives on the other coast- and when We get cold snaps- they also get them- and it happens right across the country- We had one so severe a decade or so ago that it ruined crops down south as far as florida- and another one a number of years before that that affected the whole country-
‘once every 250 years?’
again I call BS on their analysis-
