Finally BoM releases some “secret” comparison data — a snow job revealing new thermometers are not comparable

Forced, dragged to comply, the BoM finally releases a little bit of side-by-side data so skeptics can start to compare old and new thermometers

Congratulations to Jennifer Marohasy. Her preliminary study on this new data is enough to show that the electronic thermometers are not equivalent to the older liquid-in-glass ones and temperatures measured in the same spot differ by as much as 0.3C. She’s now writing to Minister Josh Frydenberg that the consequences and questions raised by this are so serious that the BoM should not be announcing any new records. We need an audit!

It’s only temperature data — ?

Skeptics have been asking for comparison data between different types of thermometers for years to figure out just how much difference they make. The BoM mostly withholds that data, sometimes deletes it, and as a last resort follows the David Jones’ recommended method of dealing with unwanted questions — “snow the skeptics” (see Climategate). After all the blog posts, newspaper articles, and requests from the Minister, finally the BoM have helpfully sent the data for Mildura in the handy form of 4,000 scanned handwritten A8 forms.

Just like this one — how much fun can you have?

Horrifying examples of deliberate tampering

Just when you thought it couldn’t get worse for the cult of the carbon scare.

Now we need to ask if the world has even warmed? I’ve always said, “global warming is real”, but the recent exposés of shocking corruption in science have made me start to wonder whether even that is true.

Today a study by Joe D’Aleo and Anthony Watts, was announced by the Science and Public Policy Institute (SPPI).

From their media release:

An extensive survey of the literature and data regarding ground and sea surface temperature records uncovers deception through data manipulation, reports the Science and Public Policy Institute (SPPI).

Authors veteran meteorologists Joe d’Aleo and Anthony Watts analyzed temperature records from all around the world for a major SPPI paper, Surface Temperature Records – Policy-driven Deception? The startling conclusion that we cannot tell whether there was any significant “global warming” at all in the 20th century is based on numerous astonishing examples of manipulation and exaggeration of the true level and rate of “global warming”.

That is to say, leading meteorological institutions in the USA and around the world have so systematically tampered with instrumental temperature data that it [...]

BREAKING NEWS: Manipulated Datasets at NASA and NCDC

Once again, the audacity and brazen manipulation of scientific evidence is shocking. These are very serious allegations.

Thermometers moved from cold mountains to warm beaches; from Siberian Arctic to more southerly locations, and from pristine rural locations to jet airport tarmacs.

There were around 6000 thermometers 20 or 30 years ago in the global data set, but in 1989-1990, the number of thermometers were reduced to around 1,500. A new study shows a dramatic pattern of artificial adjustments in the way these thermometers were included or deleted. Jonathon Coleman announced the study results tonight on his blog and also in his broadcast (see below).

Apparently officials systematically left out colder thermometer recordings and kept in hotter data, and where there were empty points on the map, they “filled them in” with calculations instead of measurements. The data was homogenized, and the adjustments always increased the warming. This is the telltale sign of chicanery. This is how we know there were artificial adjustments. Normal scientific corrections are random, not all tending in one direction.
