How not to measure temperature

This is supposedly a survey of the official monitoring units, used by scientists in their 'pursuit' to proove global warming...

Ummm... anyone see a reason why this data should be considered flawed?

It does seem that US surface temperature records may be flawed .....

But such temperatures don't really make any difference when it comes to calculating global temperatures - the USA covers just a tiny parts of the Earth's surface (as an example, if you discovered the temp record for Rhode Island was wrong, would it make much difference to the figures for the USA as a whole? ) And besides, there are numerous over methods of calcultaion temp besides surface instrumentation.


Always assuming these stations really are used? It does seem pretty incredible to us here in the UK given the rigorous manner in which the Met Office test stations before accepting their measurements. I believe Met Eireann to have similar high standards.

So are you suggesting that these surfaces are magically getting hotter every passing year? Look at the charts of the data supplied by the site your posting.

See that? The temperature is climbing in every single one of them. If, as you seem to think, temperatures were stable, then the surfaces in question would also have stable temperatures.

Good point: even if these stations are inappropriately located, it's the temperature trend that is important.


So, whilst they shouldn't be used for determining temperature records, even if they over record by 5c they can still be used to determine whether the overall temp is rising. A trend of +1c over 20 years, for example, shows up just the same wherever the station is situated.

Dont't forget about the urban heat island effect which is not taken into consideration at all.

More people are flocking to the cities all over the globe - the result?
More heat, and yet the monitoring stations haven't been moved nor has this been taken into account when the figures are presented.

The difference in the size of city's is pretty big compared to even 30 years ago.

Well... here's a good place for this...
Global warming? Scotland sees its best snow in a decade

Brrrrrrr... someone want to kick start that 'global warming' thing again? I hate snow...
