PHYSICS
have a look out the window. go on. have a look out the window. i bet you can’t see it. you can’t, can you? you can’t see that global warming that we hear so much about. what you CAN see is the postman trying to get a red gas bill about the size of a duvet cover through your letter box. there seems to be a bit too much global FREEZING going on round here. perhaps it’s localized.
one of the things that ‘they’, the so-called ’scientists’, come out with to make us cry in the night is that ’sea levels will rise’. there will be no escape from the remorseless rising of the all-consuming seas. i don’t much care personally speaking because thirst hall is a first floor flat so i shouldn’t have to struggle in the middle of the night trying to get a 42 inch plasma screen and a dfs sofa up the stairs as raw sewage slops over the tops of my wellies and fuses the lights on the christmas tree.
sea levels will rise by 16 feet!!!
that’s the news from last week. but is it true or is it scaremongering? professor the thirst will now don his scientific hat to consider the matter…
let’s do an experiment. i’ve got a glass of ginger pop, you can get a glass of sweet, sweet vodka or whatever you like. right. now put an icecube in it.
now then, what you have there is a model of the seas of the world with a melting polar icecap in it. measure how high up the glass the level of your booze is. quickly! measure it now before the ice melts!
has it melted yet? it has? good. now measure it again. record any changes. there aren’t any changes? your glass of swig hasn’t gone 16 feet higher? hunh, i thought not.
but how can this be? let’s look at this in a scientific way:
frozen water is very cold. let’s call it ‘ice’. what happens is that when scientific men make water very cold it goes, what we call, ‘BIG’. and that’s why your glass of tasty milk with an ice cube floating in it is exactly the same as an ocean with an iceberg in it which is a big ice cube.
now then. imagine a clever professor (a bit like me) who had made a secret laboratory underneath a volcano and harnessed nature’s powers to make the very cold water (that’s ‘ice’, remember?) into warm water which we will call ‘water’. the professor would notice that the ice stopped being big when it became water because the water is smaller than the ice. that’s why an ice lolly gets smaller when you eat it. the hotter ice gets the smaller it becomes. in fact, if you put an ice cube in a saucepan and leave it on the gas ring overnight it will get so small that it disappears.
imagine if all the seas were frozen. all of them. if they melted they would be smaller than before, just like that ice lolly of yours, and so if you imagine that at the moment all the seas and the polar icecaps are on their way to being all melted they would just wind up smaller than before.
so don’t worry, the seas can’t rise by sixteen feet, and if they do i expect scientists like me will have found out where the plug is and we will just send a submarine down to pull the plug out for a bit.
