Admin: Posted up for Steve, with an initial response by Miklos. The slides Steve referred to are here. My bad for not telling Miklos that.

Miskolczi theory proposes a tau (Ta if you will) significantly different from that found by at least a dozen other studies published in the peer-reviewed literature over more than a decade, as well as a number of other new relations A_A = E_D, f = 2/3 etc., etc.

A feel-good story of nature’s resiliency, “Doom and Boom on a Resilient Reef: Climate Change, Algal Overgrowth and Coral Recovery” has been making press with headlines focusing on the state of mind of the authors:
Marine scientists say they are astonished at the spectacular recovery of certain coral reefs in Australia’s Great Barrier Reef Marine Park from a devastating coral bleaching event in 2006.

CommentsSince 2006, in between promoting numeracy in education, and examples of simple statistics using topical issues from the theory of Anthropogenic Global Warming (AGW) to illustrate points, I asked the question “Have these models been validated?”, in blog posts and occasionally submissions to journals. This post summarizes these efforts.
CommentsStill on my way home, after the lecture at Newcastle University by Miklós Zágoni and myself, this will be short. The lecture was well attended, with around 50 people — surprising considering the campus is on a break and parking at a premium. The lectures were well received with a very engaged and relevant question time. There were some suggestions of disruption by anti-skeptics, but they did not eventuate.

Miklós Zágoni talk: long version
CommentsMiklós Zágoni and I will be speaking in a public lecture at 1pm on Wednesday the 15th of April at the Engineering faculty, Newcastle University, in lecture theater ES203. Miklós will speak on the theory of Ferenc Miskolczi and I will give a short introduction of the work from the blog in the last 3 years in the global warming arena.
A much longer version of my talk is incorporated into a new “Highlights” page.
CommentsSome time ago I had a brief discussion with Leif Svalgaard on ClimateAudit blog inspired by an exchange between Leif and David Archibald when the latter complained that Leif’s TSI reconstruction was “too flat”.
The sunspots exhibited cyclic variability in terms of the frequency of the cycles and that most thermostats work by pulse width modulation and some digital music with pulse frequency modulation. Both these work in a similar manner the thermal inertia of whatever the thermostat is controlling smooths the temperature variability and the pulse frequency modulation’s demodulator is a simple low pass filter often just a series resistor and shunt capacitor. In both these cases only the duty cycle or the frequency varies but not the amplitude. Below is a description of how this behaviour can be simulated with an electrical circuit emulator called ‘qucs’.
CommentsThere appears to be a very interesting fine structure to great Southern Ocean (SO) atmospheric CO2 levels if one calculates residuals relative to the ‘official’ NOAA global average. This also applies to individual Northern Hemisphere (NH) and Southern Hemisphere (SH) monitoring stations such as Mauna Loa (MLO) and Easter Island (EIC) respectively, sited in the Northeastern and Southwestern Pacific Gyres.
CommentsHere is a graph that suggests something intriguing about climate dynamics — global temperature from 1979-2009 from UAH satellite records for land, southern hemisphere ocean, and globe, each fit with a 3rd order polynomial. Also plotted is the difference between SH Ocean and Global temperatures, and the difference between SH Ocean and Land temperatures. Notice that the 3rd order polynomial of the differences is almost dead straight! The Ocean-Land difference tends to drop a bit in the last 5 years.
