Something else we can propose for the list of things caused by global warming would be Stupidity.
Why stupidity? because the schools are closing due to the snow.
I don't know that I can remember ever getting time off school except for one half day in the summer once.
I remember the last big snow storm when I went home from work early and the great storm 20 years ago or so where I was one of two people who made it into work, but schools closing (1955-1970)?
It seems to me that it is too easy today to "not bother" because of bad weather or whatever other excuse comes to mind.
So, if this cold spell is caused by global warming (which a nice man in China says it is; not Professor Prescott but Guo Hu - (this Times article http://www.timesonline.co.uk/tol/news/weather/article6975867.ece) - "Guo Hu, the head of the Beijing Meteorological Bureau, linked this week’s conditions to unusual atmospheric patterns caused by global warming. " and schools close as a consequence, then this will (as an oft repeated event which it seems to be these days) we will end up with an even stupider graduating generation than the education system is normally capable of.
The Stupidity of closing schools is not entirely caused by the heavy falls of global warming we have recently experienced.
I skimmed a few newspapers and blogs this morning, so cannot be sure where I found the story. However it seems that if schools close because of the weather, and do not actually open their doors, their attendance records are unaffected.
However, if they open, and half their pupils cannot get in to classes, the schools are penalised financially for poor attendance.
As I remember it a few years ago, when the number of school closures was fairly modest, the 'explanation' for UK schools closing due to snowfall was mainly that the teachers (rather than the pupils) couldn't easily get into school. There's a much greater tendency for teachers to commute in to their place of work from several tens of miles away than there was a few decades ago. When I was a schoolboy virtually all teachers lived in the same town as where they taught.
However when I've seen head teachers interviewed on TV this year (and also last year) about school closures they seem to have switched to propagating the health and safety type argument, where they claim to be acting because the school premises and the modern custom of the 'school run' are unsafe in these weather conditions. So it may be that head teachers are protecting the interests of the teaching profession. If teachers get the blame for substantial numbers of school closures, then it might be argued that teachers ought to relocate nearer to their place of work.
