Snowmageddon

We’re all doomed, the icy white stuff has trapped us, quick, stockpile bread, milk and petrol in case they run out.

Yes, it has snowed, a function of weather.  Its snowed a lot, we also got trapped by a wave of idiot commentators and idiotic members of the public spouting uninformed opinions regarding the way our infrastructure stands up to the snow.  I thought I’d take a look and try to explain why we appear to grind to a halt in the snow and hopefully bust a few of the myths in the process.

So, to begin, why do our roads, rails and runways seem to shut down entirely when the snow hits while no other country seems to have this problem.

This is actually part of our first mini myth; countries with a similar or warmer climate, such as Belgium, Germany and France do suffer in the snow, to roughly the same extent.  In the previous snow fall there were massive tailbacks on the autobahn and deaths in France due to accidents.  Their trains get slowed down as well.  Their rail networks hold up slightly better, but this is due to their relatively recent construction (Around 1940s-50s) and the lower frequency of services.  As to why we survived better when we got similar snowfalls in the 1960s, quite frankly fewer of us travelled smaller distances to work and did not expect shops to run 24/7.  Back then it was also not unthinkable to call and say you were snowed in.
So, what about countries with snowy climates, Russia, Canada, North America, even Sweden, Norway etc.  How do they keep things running during their far more severe winters?  Well two reasons.
First, they Engineer for it, their infrastructure is built with snow in mind, such as better facilities for clearing points when they freeze and snow drift breaks.  Similarly more of their vehicles can be equipped for snow.  They also have a larger stand-by level of snow ploughs gritters etc, as anyone who had to deal with bitter cold and severe snow and ice every year will have.  Why don’t we, because we won’t pay for the gritters or the stand by crews, and I assure you if we did then come the first mild winter some lump like Eric Pickles or the Tax Payers alliance would be out asking why we are wasting so much money on gritters that are not needed, using the usual faulty memory that plagues those who resent paying a penny of their vast fortunes in tax.
We haven’t engineered our infrastructure for this in the past because there has been little to no requirement.  It make it pretty clear that this weather is unprecedented, or at any rate rare when it doesn’t qualify to be included in the engineering specs for the construction of new roads and railways or the abilities of council vehicles and trains.

Similarly, in places like the Northern US and Canada, a “snow day” is not an uncommon occurrence, where whole schools and workplaces will close for a day.  This official closure allows the authorities to clear the roads without the rush hour traffic getting in the way and compacting the snow into ice.
Finally, as people they are better prepared, many in those parts own snow tyres or snow chains, and just about every municipal vehicle will have access to these as well.  At least now our authorities are looking into buying such things for the next cold snap, hopefully allowing ambulances and police vehicles to avoid getting stuck.

The second question is “Why do we start running out of simple things like bread and milk?”  This is easy.  Particularly for perishable goods such as bread, milk and fresh fruit and veg, most stores now work on a principal of receiving supplies of these on a daily basis, this allows them to minimise losses through spoilage by only stocking around a days worth of such items.  The down side is if the supply chain is interrupted supplies can run short.  This is not helped by people panic buying the minute the snow hits, the stores can take a small run on bread but people filling their freezers quickly wipes out their supplies.  Fuel is a similar case although will usually last slightly longer.  The pres don’t help as the minute they say there are shortages it promotes even more panic buying.  Again in cold countries, this just doesn’t happen because people are used to the weather and don’t get driven into a panic by the possibility of 24hrs without being able to drive to Tescos, something which seems to affect most brits judging by the rushes around the Xmas Day and new years closures.

People also do need to pitch in.  In Edinburgh the Army were drafted in to clear the streets, conversely, in Aberdeen, where this weather is more common most know in heavy snow you dig yourself out, then start digging out the street.  We have a certain complacency that it is the council’s job to clear the snow, which it is, however they will usually have more important routes to clear, so if you want your street cleared quickly, do it yourself.

Finally, and this will sound bad, its high expectations.  In cold countries people understand that it’s best to wait out the snow, allow the authorities to clear the roads then carry on.  We seem to insist that in the face of adverse weather everything must carry on regardless.  People seem to think that with the passing of a snowplough and gritter that roads will magically return to black tarmac.  Well sorry, a snow plough will be wrecked by hardened ice and grit ceases to melt anything below -10.  Grit is tricky to do right, too soon and it will simply be washed away or destroyed by traffic, too late and the snow can dilute the effect.  Finally, things can and still do go wrong.  The M8 closure should not have cost a transport minister his job, no opposition MSP has been able to explain how they would have acted differently.  The M8 was hit by heavy snow during the morning rush hour where, as anyone who has driven it during that time will tell you, it is full.  You could not have got a gritter through that traffic, the traffic then compacted the fresh snow to ice and this causes accidents and in some cases made some hills completely impassable.  I drove a more minor road that day and it was an experience I would not like to repeat.  We need to learn the world will not end if we take one day off work, and the govt needs to stop kowtowing to businesses complaining of the cost and call a few snow days, for the long term good.
