#DataGate: Hadley reply to first audit with foggy excuses about problems 2,000 staff didn’t find

Last week we exposed absurd errors, brutal adjustments and an almost complete lack of quality control (was there any at all?) in the key HadCRUT4 data. The IPCC’s favorite set is maintained (I’m feeling generous) by the Met Office Hadley Centre and the Uni of East Anglia’s CRU in the UK.

Finally the Hadley Met Centre team have replied to Graham Lloyd regarding John McLean’s audit. They don’t confirm or discount any of his new claims specifically. But they acknowledge his previous notifications were useful in 2016, and promise “any errors will be fixed in the next update.” That’s nice to know, but begs the question of why a PhD student working from home can find mistakes that the £226 million institute with 2,100 employees could not.

They don’t mention the killer issue of the adjustments for site-moves at all — that’s the cumulative cooling of the oldest records to compensate for buildings that probably weren’t built there ’til decades later.

Otherwise this is the usual PR fog — a few outliers don’t change the trend, the world is warming, and other datasets show “similar trends“. The elephant in the kitchen is the site move adjustments which do […]

#DataGate! First ever audit of global temperature data finds freezing tropical islands, boiling towns, boats on land

What were they thinking?

The fate of the planet is at stake, but the key temperature data set used by climate models contains more than 70 different sorts of problems. Trillions of dollars have been spent because of predictions based on this data – yet even the most baby-basic quality control checks have not been done.

Thanks to Dr John McLean, we see how The IPCC demands for cash rest on freak data, empty fields, Fahrenheit temps recorded as Celsius, mistakes in longitude and latitude, brutal adjustments and even spelling errors.

Why. Why. Why wasn’t this done years ago?

So much for that facade. How can people who care about the climate be so sloppy and amateur with the data?

Absurdity everywhere in Hadley Met Centre data

There are cases of tropical islands recording a monthly average of zero degrees — this is the mean of the daily highs and lows for the month. A spot in Romania spent one whole month averaging minus 45 degrees. One site in Colombia recorded three months of over 80 degrees C. That is so incredibly hot that even the minimums there were […]

Mystery Divergence? There’s a strange gap between temperatures measured by satellites and on the surface

Right now there is a very odd divergence of satellite and surface thermometers. It started about two years ago. It is not like the El Nino of 1998, where all four rose together, and satellites recorded a higher spike than the surface records. This time around the satellites are lower. In the graph below, David Evans uses the older UAH official set, not the new “beta” version which would show UAH much closer to RSS and would make this divergence look even more stark.

According to the theory of Man-Made Global Catastrophe, the satellites, which record temperatures in the lower troposphere, should be warming faster than the surface. Where is that trend?

El Ninos slows ocean turnover, keeping a layer of warm water at the surface instead of stirring it in with the cooler water below. For some reason the thermometers near airports, carparks and cities are picking up the ocean warming better than the satellites. Hmm?

I’m wary of concluding anything at this stage. There was a big gap in 2007 which resolved in two years. This gap is longer, but may resolve soon too.

Then of course, there’s the point that even the past can change, […]

Man-made adjustments transform cooling to warming in Paraguay, South America

It’s not fossil fuels causing global warming, it’s man-made adjustments. Stop the adjustments!

In South America, there are hardly any rural land thermometers. GISS tells us the area is warming (see the map below). Paul Homewood looked at the raw data. There are only three rural stations currently operating in the area, Puerto Casado, Mariscal, and San Juan, and they all show a raw trend that falls. As in so many other situations, after adjustments, all three show a rising trend. The changes are breathtaking. In Mariscal raw temperatures of 25.5C turned out to be “really” 22.5C. (Those 1950 thermometers were hopeless 😉 ). In San Juan Bautista, and Puerto Casasdo the old thermometers get adjusted down by around two degrees. Perhaps there are reasons for the adjustments, but if old thermometers so so bad, and station changes have made such a difference, why does any scientist pretend we can calculate global temperatures accurately?
