Anthony Watts is lashing out at all and sundry. He is desperate to find some remnant from past history that will prove that the world isn't getting hotter (archived here).
Today he's stretching way back to July 1936 in the USA. He's absolutely convinced that July 1936 was the hottest month on record in the contiguous USA. And he may be right. Who knows.
Anthony reckons that back in July 1936 the average temperature for the contiguous USA was 76.8°F. In July 2012 it was only 76.77°F. At least according to the latest NOAA data he found.
Not only that, but he's found proof, PROOF - in black and purple and white - that NOAA adjust past temperatures. Oh, golly gosh. Would you believe they adjust past temperatures downwards. Two years ago it was 77.4°F in July 1936 and now it's only 76.8°F. Not only that but they adjust recent records downwards, too. In July 2012 two years ago it was 77.6°F and now the record shows it as 76.77°F.
If there's one thing that Anthony Watts cannot abide it's change. Especially change to his most treasured possession, the average temperature in the contiguous USA for the month of July 1936. How dare anyone adjust the record. Who cares if there were time of observation corrections to be made. Who cares if someone decided to add some new data unearthed from some old ledger. The record is sacred and must not be touched at penalty of a blog article at WUWT.
Anthony's given up looking for hotter years, now he's down to months. Won't be long before it's weeks, then days, then minutes, then seconds.
Imagine the poor chap fifteen years from now, sweltering in the latest heat wave. He'll be hunched over paper records from the 1930s whimpering, "I know it's here. It's got to be here somewhere. I'm sure that one day in 1936, somewhere in the USA must have been hotter than today." You could almost feel sorry for the man if you didn't know he was such a shady character with a shameful record of unethical behaviour.
This is from the USA records, just in case you thought the USA was getting colder and was heading for an ice age. The average temperature for the entire year (not just one month) in 2012 was higher than any year in the 1930s. It was hotter than the hottest year in the 1930s. I've put a line across for comparison. The hottest year in the 1930s was 1934. But it was hotter again in 1998 and 2006 and much hotter still in 2012.

But it's not the "hottest" that's so important. It's the overall trend. Look at all those warm years bunched up together to the right of the chart. Keep your eye on that end as time goes by.
There were a few warmer than average years in the first half of the twentieth century in the USA. 1921, 1931 and 1934 stand out as being very warm years by comparison with the rest of the century. After the 1950s it got colder for a bit, though nearly not as cold as some of the earliest years in the instrumental record. Since the early 1980s it's just kept getting warmer, with only one or two cooler years. The last time there was a year colder than the twentieth century average was almost twenty years ago in 1996. The last couple of decades is almost a solid block of warmer years. Quite different to the twentieth century and earlier.
And while Anthony has his nose buried in the 1930s in the USA, this is what's been happening in the rest of the world.

From the WUWT commentsThe comments are pretty ordinary. Mostly they are just wailing that raw temperature records are adjusted. It's probably fair to say that most WUWT-ers are conservatives and conservatives don't like change of any kind.
NotAGolfer doesn't know what he's talking about but he's memorised the words of the meme he's meant to parrot and says:

Anthony, wake up! It’s intentional. They are trying to make it appear that the warming trend is greater than it is. It’s beyond obvious. Do you still believe Clinton didn’t inhale?
Pamela Gray makes a more sensible comment for a change and says:

On the other hand, this is kind of like the TSI/SSN data series. There are, as we have discussed, different reconstructions and observations that differ from one data set to another. The fact that it is being corrected is a matter of scientific correction. Not necessarily evidence of wrong doing.
Could this be a good sign when dealing with a very horrible set of measuring issues?
Lawrie Ayres complains that the keepers of the records are all warmists except for the Russians and Chinese (oh how sentiment has changed since the 1950s):

The BoM in Australia has been fiddling the books for ages in order to arrive at “the hottest summer ever” and when an audit was about to take place cancelled that system and started another which was just as fraudulent. We do have a new government with a representative that’s a real scientist. He has been calling for another audit and will probably get it as many Coalition members are skeptics. The whole land based temperature system is in disarray as the keepers of the records all seem to be warmists except for the Russians and Chinese.
