Sun, Weather and Climate

The book, 'Sun, Weather, and Climate' (2005) by John R Herman and Richard A Goldberg is a reprint of a book originally published in 1978. It was reprinted on two occasions and published in Russian and Chinese, and seems to have become a classic of its kind, a forerunner of modern climate research. It is of great interest in the study of Earth's climate - hence the need to flag it up again (as I had a post in 2013 on the same book). William provided the link below.

Sat Nav and Aurorae

At https://tallbloke.wordpress.com/2017/03/15/auroras-affect-sat-nav-system... ... This is an interesting one as aurora are produced when gas particles in the Earth's atmosphere collide with charged particles emitted from the Sun. The resulting plasma turbulence has long been thought to be the reason why global navigation satellite systems go awry. New research casts doubt on this view.

Meteors Humming

Gary sent in this link - www.dailymail.co.uk/sciencetech/article-4201328/Study-identifies-cause-s... ... on the day after Wikipedia banned the Daily Mail claiming it was a source of fake news. You may wonder why Wikipedia, also renowned as a source of fake news, would bother - but you have to take into account the thought police that patrol the pages of Wikipedia (looking out for anti-CAGW postings).The David Rose 'bombshell article' has really rattled the gilded cage of the CAGW faithful. 

Mid Holocene Anomaly

At https://phys.org/print405675862.html ... we learn there was what is thought to be advanced solar activity smack bang in the middle of the Mid Holocene Warm Period. The evidence comes from tree rings in long lived bristlecone pine trees. The researchers suggest it may involve a change in the Sun's magnetic activity (a super flare) or a number of solar flares arriving in a burst, one after the other.

Blue Jets Lightning

  ... an image of a blue jet of lightning leaping up from the atmosphere of the earth. The picture was taken by a Danish astronaut onboard the International Space Station.

Here is an image of the green comet coming our way this weekend. It has lost its tail as it rounded the sun - like Samson, it is bald.


At https://wattsupwiththat.com/2017/02/01/still-far-more-worrisome-than-glo... ... just noticed this one after visiting Anthony Watts place. Solar physicist Leif Svalgaard informed Anthony of the possibility of a Carrington style event (a large CME in 1859). It could bring down the electricity grid system and damage satellites etc (the same thing that regularly pops up when this sort of event is mentioned and surprisingly given short shrift by some of the commenters).

plasma behaviour

At www.thunderbolts.info/wp/2017/01/27/at-any-scale/ ... we have further clarification on plasma behaviour which is useful as we lead up to our speaker meeting in April which will be addressed by Bob Johnson. This time the issue is the so called 'fast radio bursts' - fast release of energy that lasts just a few milliseconds. Obviously, this was an unknown until the advent of recent instruments. Blink and you would miss them.

Earth's Magnetic Field

This link was sent in by a member of SIS - http://crev.info/2017/01/earths-magnetic-field-3/ .... which concerns a New Scientist piece by Marcus Woo on the magnetic field. It is useful as it illustrates how some people may reinterpret what other people say - and no doubt I do this all the time as well. What Woo appears to do is point out anomalies concerning earth's magnetic field - and most science journalists would not bother to mention anomalies so Woo is to be congratulated.

Strange Earth

    January 6th in northern Ontario, weird light show. Go to www.livescience.com/57482-light-pillars-photo-ontario.html ... and for some weird geological pictures there is a video show at www.msn.com/en-us/travel/tripideas/californias-geological-phenomena-that...

liquid iron jet stream

A liquid iron plume streaming from Earth's core has been likened to an internal jet stream. It is claimed that it is actually accelerating which is interesting as the magnetic north pole is behaving oddly. The European Space Agency's Swarm satellite system is providing sharp x-ray images of the core according to Phil Livermore of the University of Leeds (the findings are published in the December issue of Nature Geoscience). The new information is helping scientists to understand the earth's magnetic field.
