Land and Water, heat and not so heated

http://joannenova.com.au/2010/07/did-giss-discover-30-more-land-in-the-northern-hemishphere/ Frank Lansner has been tinkering with the NASA GISS dataset - trying to understand how it works, or rather, how arch AGW adherent James Hansen gets his numbers. The northern hemisphere has a ratio of 40 per cent land to 60 pere cent ocean, which is used by Hadley CRU in the UK (HadCRU at UEA).

Earth's collapsing atmosphere

At www.physorg.com/print198429352.html there is a report on a paper at Geophysical Research Letters June 19th which says there was a contraction of the  thermosphere during the deep solar minimum of 2008-9. It is known to cool and shrink when solar activity is low - but in this instance, the collapse was almost 3 times greater than low solar activity by itself can explain - from their mathematics.

Asteroids and near earth objects

At http://cosmictusk.com George Howard has placed a New Scientist video of a flight across the Tunguska impact site in Siberia, with some close-ups of Lake Cheko which he thinks resembles a Carolina Bay.

Magnetic Powerhouse

At http://news.nationalgeographic.com/news/2010/07/100715-science-space-mercury/ ... a flyby of Mercury revealed a huge power surge that 'we clearly do not understand' according to the story. The electromagnetic storms took place in Mercury's magnetic tail, and this forms when the solar wind pushes against a planet's magnetic field and the deformed field takes on a windsock shape. It says Mars and Venus do NOT have magnetic fields or tails - is this true?

A tectonic computer model

at www.physorg.com/print198495599.html July 16th ... a group of earth scientists has developed a new way to explain the global movements of tectonic plates on the surface of the earth. For example, the Basin and Range Province in Nevada was created by a plate sliding beneath the North American continent - just 30 million years ago.. This is fairly recent as far as geological time is concerned, and the paper, in Science July 16th, suggests plates in the modern world move at the rate of around a few centimetres per year.

Planetary Tails

National Geographic July 15th http://news.nationalgeographic.com/news/2010/07/100715-alien-planet-comet-like-tail/ is a story about a planet orbiting so close to a star that its atmosphere is being blasted away, forming a gaseous comet-like tail - according to astronomers in the Astrophysical Journal of July 10th.

Tutankhamun's DNA

At www.eutimes.net/2010/06/king-tuts-dna-is-western-european/ is another post sent in by Gary Gilligan, as he has a strong interest in ancient Egypt. It claims Zahi Hawass has not released the DNA results from Tutankhamun's body although he has publicised the findings of the scientific research in respect of the manner of his death, and his relationship to other mummified bodies of the late dynasty 18 period.

Climate and the sun

www.nguno/en-gb/Aktuelt/2008/Less-ice-in-the-Arctic-ocean-6000-7000-years-ago/ is an article that dates back to October 2008 but is interesting as raised beaches on the north coast of Greenland are said to suggest ice cover in the Arctic Ocean was greatly reduced some 6000-7000 years ago (Astrid Lysa, a Norwegian geologist, and colleage Eiliv Larsen of the NGU, Norway).

Dark matter and the Sun

At www.wired.com/wiredscience/2010/07/dark-matter-sun/ ... this article and the web site were noted by member Gary Gilligan and forwarded to In the News at news [at] sis-group [dot] org and other members are invited to send details of web sites and papers, and newspaper reports, that they think might interest other members.

black hole, cold thunderstorm

At www.physorg.com/print198173823.html researchers have discovered a black hole emitting powerful jets of particles that spew forth some 1000 light years. Black holes are usually associated with X-rays rather than jets of particles (see Nature July 8th).
