Hiding the decline, again

You may have seen reports that last month in America was “the hottest July on record.” Well, Anthony Watts (WUWT) noticed it, too, and went to work trying to see if, for once, the global warming alarmists got it right.

Guess what? They didn’t.

In fact, Watts noticed a temperature two-step that in the old days would have snowed the populace (damn right, pun intended). Instead, it’s just the latest incident of alarmist fudging exposed.

For those who are keeping track (admittedly not easy given the numbers), we are now at thirty-nine examples of data manipulation, errors, and other shenanigans from global warming alarmism, and that’s just from what I’ve been able to blog on this subject over the last two and a half years.

First off, Watts noticed that July 1936 (the actual hottest July on record) isn’t what it used to be anymore:

And with all the adjustments that have been going on, which 1930′s are we really talking about? The real one or the adjusted one? NASA GISS uses NCDC adjusted data, which according to this graph from Steve Goddard, suggests there’s been a whole lot of adjusting going on.

The graph below shows the almost two degree US upwards adjustment trend being applied by USHCN between the raw thermometer data and the published monthly data.

The adjustments they are making are greater than the claimed trend, meaning that all man made US warming is occurring inside ORNL and GISS computers.

Read that last line again: “The adjustments they are making are greater than the claimed trend, meaning that all man made US warming is occurring inside ORNL and GISS computers.”

Yikes!

Of course, rewriting the past is not enough, and Watts also finds that the NOAA is refusing to use its new USCRN network for temperature reports. Why not? Here’s why not:

Using the old network, NOAA says the USA Average Temperature for July 2012 is: 77.6°F

Using the NOAA USCRN data, the USA Average Temperature for July 2012 is: 75.5°F

The difference between the old problematic network and new USCRN is 2.1°F cooler.

This puts July 2012, according to the best official climate monitoring network in the USA at 1.9°F below the 77.4°F July 1936 USA average temperature in the NOAA press release today, not a record by any measure.

So…”adjust” the past so it looks cooler, use the inferior measurement network so the present looks hotter, and Heston presto: you have a new “record” and a perfect alarmist press release!

Nice try, fellows, but that’s not going to work anymore.
