### Homogenising the temperature

There seems to be a strange habit going on when it comes to temperature records.

Let me explain.

A temperature record starts off being a record of what a thermometer says the temperature is in a particular place at a particular time of day.  That seems fairly easy and simple.

You'd think it was then extremely straight forward to subsequently work out the average temperature around the world.  Assuming you have a thermometer every x kilometres, then logically, adding all the temperatures together and then dividing by the total number of records gives you the average.

This can be all the temperatures at a particular time of day, or maybe all the temperatures at their highest or their lowest.

But, of course, nothing is simple.

Nope, we have to make it far more complicated.

There's a process called 'homogenisation'.

This 'homogenisation' is when the record of the original temperature reading is changed into a nice new reading that is in some bizarre way now 'fit for purpose' whilst the original 'raw' actual readings are not. This is usually done on a country by country basis.

Most bizarrely, the actual original readings are often lost or discarded at this point, with those wishing to apply different mathematics to the 'raw' data unable to get hold of it without a long drawn out process of using Freedom of Information Acts.  Sometimes after years of waiting for the 'raw' data, those applying for it are told it's been lost.

When the figures are then centralised and collated by the various billion-dollar funded 'global' agencies, the already homogenised figures are then ... guess what?  Yep, they are further homogenised!

At this point they have now reached a new figure that's even further removed from the original and rapidly long forgotten reading that once resided on that thermometer.

For reasons that don't quite make sense either, a large part of this double homogenisation seems to result in temperature readings from the past going down compared to the original readings.  And ... guess what?

That's right!  Temperatures from the present always seem to be double homogenised to go up compared to the original readings.

Hmmm.  How can this be happening?  I mean, it makes no real sense, does it?

Here's an interesting statistic: Using the raw original readings and doing all the mathematics gives no 'global warming' whatsoever.  Indeed it gives a 'global cooling' for the past 16 years.

Only as a result of the homogenisation process do you get 'global warming', and the recent 'global cooling' replaced by a stagnant or stationary period, but not cooling.

So, how and why is this all being allowed to happen?

Anybody would think there was a deliberate ploy to enhance the belief that we have global warming and hide the fact that actually, we don't.

Why would anybody want to do that, eh?
