Forbush Decreases

At www.spaceweather.com September 18th .... on the 12th a CME hit Earth's magnetic field igniting an intense geomagnetic storm - and providing England with a week of summer temperatures. Students launched a helium Balloon into the stratosphere, expecting to measure lots more radiation than normal. Instead, them measured less - a lot less. Why?

Well, it seems that when the CME swept past the Earth it gathered up a lot of cosmic rays that normally occupy the upper atmosphere - sweeping them away. This process was first discovered in the 20th century by Scott Forbush.

The Gulf Stream in the Ice Age

At http://phys.org/print330072076.html ... an article in the journal Geology claims the Gulf Stream still flowed into the Nordic seas during the coldest parts of the Ice Age. Is this possible?

Ripples in Rock

Various explanations for the presence of what look like ripples or creases in sedimentary rocks have been proposed over the years. Some see them as evidence of long periods such as the Milankovitch cycles, and others see them as seasonal tide lines (a very short period as far as geochronology is concerned). At http://archaeologynewsnetwork.blogspot.co.uk/2014/09/ripples-in-ancient-... ... we have an even shorter stretch of time.

The nanodiamond debate

At http://cosmictusk.com/university-of-chicago-nanodiamonds-prove-cosmic-im... ... which is a reference to the recent Younger Dryas event. The same story is at http://wattsupwiththat.com/2014/09/11/microscopic-diamonds-suggest-cosmi... ... where the first comments become somewhat heated. However, the very first comment is somewhat reflective in that it says that if you ignore the Younger Dryas event the warming after the Ice Age is a straight line right into the Holocene (at 11,500 years ago).

volcanoes ... standard theory awry?

In this instance, mainstream theory is being revised in a mainstream kind of way - the story is at http://phys.org/print329398219.html

Ozone scare being revived

At http://wattsupwiththat.com/2014/09/12/un-global-warming-propaganda-campa... ... the attempt to keep the CAGW bandwagon rolling is changing tack as we approach this year's Climate Summit in New York, the annual bean feast which sees the draining of lots of wine bottles and the talking themselves senseless. They are under pressure as the world has stopped warming and the cat is out of the bag. Hence, the latest wheeze.

On a Plait

George Howard takes another pop at Phil Plait and his 'consensus science rules' blog after he had a go at Chandra Wickramasinghe and the theory of Panspermia. George considers Panspermia to be a friendly cousin of neo-catastrophism and worthy of defence on the same grounds. Both subjects endure a lot of criticism, especially by people such as Plait who instinctively disapprove and oppose new ideas as if it is an affront on them personally rather than a different way of looking at things, in the spirit of science.

Climatic blips from Egypt

At http://news.ucsc.edu/2014/09/egyptian-mammals.html ... a paper in PNAS (Sept 8th 2014) sets out to assemble a record of large mammals living in the Nile Valley - over the last 6000 years. Therefore it doesn't seek to catalogue the fauna of the early Holocene when the Sahara was a much wetter environment. The arid climate appears to have set in as a result of a series of step changes - periods of very dry climate that correspond with low growth tree ring events.

Fossils and Things

At http://archaeologynewsnetwork.blogspot.co.uk/2014/09/exceptionally-well-... ... concerns insect fossils found in rocks in the Rhone Valley, in limestone outcrops. A new species has been found, a water treader - the kind of aquatic bug you might find in a garden pond. Now, limestone is consider to have an origin in shallow sea locations such as lagoons and the Rhone Valley limestone has lots of fish and marine shells and even plants that are assumed to have been washed into the tropical sea.

Planet formation

At http://phys.org/print329463697.html ... the question is, how do planets form? Okay, we have the mainstream model in which the idea is that dust from the remnants of supernova acretes into discs around young stars. Such dust is thus thought, over time, to clump together in order to form pieces as big as pebbles, and over time, into even bigger and bigger pieces that eventually gell into a planet size body. However, at the point the pebbles form the consensus view is not entirely sure just how they expand into bigger objects.
