In a perfect world there would be AWS's every 10km over the whole country, doppler weather radars every 200km over the whole country and upper air stations spaced similarly. So which funding barrel should be robbed to set all this up, staff and maintain it..

Yes they MAY have legitimate reasons to adjust data, but to the degree pointed out just seems to me, to be totally unacceptable. I get tired of reading the "justifications" for the data manipulation - and that is what it is - manipulation. I’ve said it before if I was to adjust any of the data my laboratory produces I'd be out of a job real fast. If the data is so wrong then remove it - don’t adjust it - that’s wrong wrong wrong.

CB keeps producing articles/reports or whatever to explain the reasons for these adjustments. The can give all the excuses they damn well please and all I have to say is its not Science to go tweaking your results. Report the real data and let people make their own decisions. If the issues is UHI or thermometers too close to air con vents or whatever damn excuses they need then ditch the data its not right - don’t adjust it take it out of the equation and data sets if it stinks things up that bad, otherwise you wind up with a nest of rotten eggs and they my friends will turn anyone’s stomach once they are cracked open to reveal the rot.

I could imagine food processors adjusting their data. Oh we had salmonella in that batch of infant formula but the batch we made yesterday and the day before didn’t so well use that data to release the batch to the public, In fact the batch would be destroyed and an investigation undertaken to find out how it came to be contaminated.

We have lots of things in place to check our data - blank controls, SRM materials (materials with known values), calibrated glassware, balances, thermometers etc etc so the data produced by the lab can be verified before its released to anyone and before product can be released to the consumer.

If you get booked for speeding by radar or cameras don’t we have the right to question the calibration of the equipment used to cause the fine to be raised in the first instance. Should it not be correctly calibrated or can we ask for the police to adjust the speed up/down do to other factors – it wasn’t me it was the car next to me, it was the sunlight….I was on my way to hospital….I question it and we all should and not take what we are told for granted. Some of the responses - reasons - excuses for data adjustment just seem too bogus to me.

Are weather data suppliers not providing data, which is paid for by the public and private enterprises? Should we not have the right to question that data and how it was obtained - how it was calculated and reported?

The Argo buoys that were being questioned because the data produced was not fitting what was expected. If the calibration of the buoys were confirmed then that data is usable – it should not be eliminated because it doesn’t fit expected outcomes. Thats not Scince - check the equipment and if the data doesnt fit find out why.

Recently we had a huge rainfall down poor in my hometown. Most home gauges recorded well over 100 mm. The local Bureau station AWS recorded very little (don’t recall the actual amount but well below 10 mm. Their instrument was broken due to a grass seed being lodged in the rain gauge. What did the bureau want to do? They wanted to use the rainfall data for us from an AWS that was 35 Km’s away who reported rain fall of less than 40 mm for the same period – how is that legitimate?

I’m tired of excuses for data adjustment. I’ll say it again – if the data is wrong and questionable then it’s not usable. You may wind up with pockets of missing data but I would prefer that to data that’s just plain WRONG.

And just for your information Anthony - it is entirely possible for the U.S to not warm at the same rate as the rest of the Globe due to local climatic factors. That fact in no way negates the warming effect of CO2 globally.

Bit hypocritical there mate seeing as thhough you are the one that keeps posting individual daily records for the US and say hey look its because of climate change! Now you say its possible it isn't warming as much cause of local climatic factors? It is called weather mate! Who is to say that in 5 years time all these recent heat records will be overrun by cold records. The earths temperature has flucuated through its entire history, it has been colder in the past and indeed hotter...way hotter! All you do is pick and choose the things that make it look like your dodgy argument is valid...the truth is we all see straight through you.

Therefore, IT'S NOT GLOBAL WARMING. If it's warm in the N/H, it's cool in the S/H.

Both hemisphere's have the same amount of CO2 in them.

Go figure....

Is that all you got Anthony? A dodgy graph from god knows where? You could at least provide a link to the graph so that we and the High Court Judge can see if it's legitimate or not.

Yes - it has been hotter in the past - that is well understood - what is making it hotter now - we also know that - it is due to the CO2 from human activity.

what is making it hotter now - we also know that - it is due to the CO2 from human activity.

NOAA didn't construct that graph. Who did it and has their work been verified?
