Wake turbulence rules for A380s require other aircraft to observe minimum separation distances of 5-8 miles in a variety of situations.

A harrowing freak air accident that has only just been revealed saw an Airbus A380 commercial jetliner flown by Emirates cause a much smaller business jet passing beneath it to flip upside down and plummet thousands of feet, reports the IB Times. The incident is a sharp reminder of why passengers should always wear their seat belts.

According to information obtained by the Aviation Herald, on the morning of 7 January an Emirates Airbus A380-800 was flying from Dubai to Sydney. While the aeroplane was en route over the Arabian Sea, roughly about 630 nautical miles southeast of Muscat, a Bombardier Challenger 604 business jet operated by German carrier MHS Aviation passed by 1,000ft beneath it.

sheep-attackIt’s a bit like being savaged by sheep. Anthony Watts and his psychotic sidekick Willis the drug-addled cowboy are at it again. They’re trying to undermine the work of Ned Nikolov and Karl Zeller, who gave an excellent presentation at our highly successful London Conference. Their theory covers the underlying physical principles which determine surface temperature across a range of solar system bodies with radically different parameters in terms of insolation, surface pressure, atmospheric composition and rotation rates. There’s not a snowball on Venus’ chance of Watts or Willis understanding it, as they amply demonstrated last time they had a go.

This Science Daily story dates back to March this year, but the water bridge phenomenon itself is nothing new. In the linked video [see note below] Robert Johnson discusses ‘Plasma Behavior in the Floating Water Bridge’.
So how do floating water bridges defy gravity?

Together with the Wetsus research centre in The Netherlands, researchers of TU Graz have managed to produce electrically charged water by means of a floating water bridge.

Until its scientific rediscovery in 2007 at TU Graz, the “water bridge” phenomenon, discovered in the 19th century, had sunk into oblivion.

It’s finally happening. Thanks to Herculean efforts by Niklas Morner, we are presenting a two-day conference in central London on the 8-9th September. Speakers are coming from all over the world to present their work, and it is not to be missed!

conf-logo

Take the 8-9th September off work and join us for this historic event. The first UK climate conference in decades which will counter the scaremongering of the IPCC with a cool, rational approach to the study of climate change, presenting alternative explanations, new data, theory and commentary. Topics include solar-planetary theory, causes of ENSO, sea ice extent, sea level, ozone depletion, volcanos, regional forecasting, journal gatekeeping and many more.

The list of contributors is long, we are packing a huge number of presentations into this two day event. Speakers include Niklas Morner, myself, Ned Nikolov and Karl Zeller,  Nicola Scafetta, Per Strandberg, Jan-Erik Solheim, and thats before lunch on day one! Piers Corbyn will be there! So will  Christopher Monckton! See the full programme and the extended abstracts in this 35 Megabyte document for full details. There are also some travel and booking details on the geoethic.com website. An updated version is available on reseachgate

Near Earth's magnetic poles, some of Earth's magnetic field - shown as red in this diagram - loops out into space and connects back to Earth. But some of Earth's polar magnetic field connects directly to the sun's magnetic field, shown here in white. [credit: NASA}

Earth’s magnetic field is more dynamic than expected, as Phys.org reports. Old-fashioned observation gets a result.

During the Antarctic summer of 2013-2014, a team of researchers released a series of translucent scientific balloons, one by one.

The miniature membranous balloons – part of the Balloon Array for Radiation-belt Relativistic Electron Losses, or BARREL, campaign – floated above the icy terrain for several weeks each, diligently documenting the rain of electrons falling into the atmosphere from Earth’s magnetic field.

Then in January 2014, BARREL’s observations saw something never seen before.

Logarithmic spiral beaches

The Talkshop is dabbling in education today with this extract from Wikipedia.

A logarithmic spiral beach is a type of beach which develops in the direction under which it is sheltered by a headland, in an area called the shadow zone. It is characterized as a logarithmic spiral because if you look at it in plan view or aerially, it represents the same shape that is created from the logarithmic spiral relation.

These beaches are also commonly referred to as ‘half heart’ or ‘crenulate’ shaped bays, or ‘headland bays’.

Let’s put aside the conclusion that CO2 makes the antarctic cool the earth. In the Schmithüsen paper (http://onlinelibrary.wiley.com/doi/10.1002/2015GL066749/full) they claim to have made the calculation, and it shows that. However, what is new? This had been measured with – gosh – real data some 45 years (!) ago. See here the Nimbus data from 1971 in Fig. 12d (http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19710026041.pdf )

Further, look at Schmitthüsen’s Fig 2. You see the spike on the CO2 pimple at the South pole at a Spectral radiance of 2.5. And exactly at the same level for the US Standard atmosphere. This is at least consistent with an interpretation that CO2 radiates the same everywhere on earth, but becomes only visible, when the background black body radiation from the ground is low enough. And this requirement is fulfilled only at the very cold south pole. So, what is left as excitement?
