Interfacion Pty Ltd is pleased to announce that the QED PI Detector has been modified to allow the use of DD (double D) coils. This change involves a simple change to the electronics within the control box.
The firmware has also been upgraded to include a further improved Ground Balance.
All detectors being delivered to new customers from Monday 5th August 2019 will already have the above upgrades included.
As a show of commitment to all QED owners, the hardware modification to allow use of the DD and CC coils will be provided at no cost.
Of course and as per the QED warranty, the firmware update is provided free of charge, except for P&H.
Any QED owner who plans to attend the Laanecoorie Bash is encouraged to bring their detector along and have it upgraded at no cost.
Standard postage and handling arrangements apply to other owners. Send via Australia Post the box (minus batteries) along with a pre-paid, pre-addressed bag/box to:

Non-peer-reviewed manuscript falsely claims natural cloud changes can explain global warming
CLAIM
"During the last hundred years the temperature is increased about 0.1°C because of carbon dioxide. The human contribution was about 0.01°C."
SOURCE: Jyrki Kauppinen, Paul Joseph Watson, Pekka Malmi, Fox News, Sky News Australia, Summit.news, Zero Hedge, 11 July 2019  
DETAILS
Flawed Reasoning: The authors' argument claims a correlation between cloud cover/relative humidity and global temperature proves that the former caused the latter without investigating whether they have the relationship backwards.
Inadequate support: The source of their claimed global cloud dataset is not given, and no research on their proposed mechanism for climate change is cited.
Fails to provide correct physical explanation: The manuscript incorrectly claims that the rise of atmospheric carbon dioxide is caused by release from ocean waters. It also provides no explanation for the claim that an increase in relative humidity causes global cooling.

Finally, after using a bunch of nonsense calculations to say that 0.1 °C warming is from CO2, they say that 90% of the change in CO2 is caused by the oceans. This violates conservation of mass from basic chemistry13: the oceans are actually absorbing CO214,15 which, again, is the complete opposite of what Kaupinen and Malmi claim. Without claiming the opposite of reality, their conclusions cannot be supported.

Victor Venema, Scientist, University of Bonn, Germany:
This text may look like a scientific article to a lay-person, but I would not accept it as a bachelor thesis . It does not cite its data sources, it does not discuss the uncertainties in the data, nor does it discuss that other cloud data sets find the opposite trend. It does not explain sufficiently how computations were made to make the study reproducible and understandable. It does not discuss the conflict between its claimed low climate sensitivity and climatic changes in the (deep) past. It cites six references: one to the IPCC report and one scientific article, both of which they apparently did not read or understand; two of their own unpublished manuscripts and two of their own articles in questionable or predatory journals.
Still even if we would grant this work to show that climate models do not give the right estimates of climate sensitivity, it would still not show that the Earth has a low climate sensitivity. There are several independent lines of evidence which give us estimates of the climate sensitivity, only one of which is climate models. A summary of this evidence can be found in the figure below from the last IPCC, which the authors cite.

Inhere proves time and time again  why he is a climate denier dope par excellence !

doug smile


Now i have to laugh! The denier dope now says-"Even I could pick an error in their list of reasons."
Come on inhere give us another laugh and again prove that you are a climate denier dope par excellence by telling what the error is in their list of reasons and why!!
Put up or shut up!!

Doug, no point in trying to reason with Inhere as he is not very bright and a failure, not only in his previous business, but in every thing he has ever done.
