Polish and the Taurids

At http://scienceinpoland.pap.pl/en/news/news,4128a3,taurids-can-be-a-sourc... ... Back in the 1990s David Asher of the Armagh Observatory studied the Taurids as part of his work on a doctorate. He noted that sometimes observers reported on Taurid maximums (higher density than at other times) that contained a large number of very bright meteors.

Gobi Desert was Wet

The Gobi desert is nowadays the second largest desert in the world and suffers from a drastic lack of rainfall. It wasn't always so. Go to http://scienceinpoland.pap.pl/en/news/news,410066,archaeologist-many-tho... ... Polish archaeologists are getting like Polish plumbers as they are popping up all over the world. Are they doing archaeology at a reduced rate?

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.

Black Holes fighting

Black holes again - clashing black holes (what is that all about) - see www.thunderbolts.info/wp/2017/01/25/black-wreckage/ ... which is a reference to the wreckage left behind when two galaxies collide and the black holes at their hearts merge forcefully together (see earlier posts on the black hole subject). NuSTAR was launched by NASA in 2012 and one of its roles is to look for x-ray flashes out there in the deep universe.

homogenisation

Homogenisation of temperature data is a sore point with climate sceptics as it air brushes out the warmth of the 1930s and the 1870s. In other words, the warmest decades of the 60 to 70 year solar cycle do not show up as they should. Philip Lloyd, writing at https://wattsupwiththat.com/2017/01/28/homogenization-of-temperature-dat... ...

10,000 years

    ... This chart is interesting not just for the periods of warmth but for the incidents of cold. The 8000 years ago event sticks out like a sore thumb (6200BC) and likewise an event just before 5000 years ago and around 4300 years ago. In contrast, we don't have a cold blip at 1200 or 1000BC to qualify as the end of Late Bronze Age event. Instead, it is very warm. Why would that be? Was something different going on?

Trilobites

Trilobites look like ancient woodlice but they differ in that they lived in the sea and had soft parts. They go back 450 million years ago - very old on the tree of life ...

Moon, Mars, and Flares

At https://phys.org/print404637022.html ... isotopic similarities in material that formed the earth and the moon. Where did it all come from and when did they arrive? In Nature (Jan 25th) we are told earth accreted from an isotopically homogenous reservoir. Soon after the earth formed 4.5 billion years ago, and as its core grew, that same core attracted metals (arriving from space). The material that makes up enstatite meteorites (also defined as chondritic) make up a great part of the earth. In addition, the moon is isotopically similar also.

Someone must be ...

Someone must be reading New Scientist on a regular basis as at http://crev.info/2017/01/secular-ocean-theory-evaporates/ ... they are once again blinking in the headlights according to the chap at this link. This time the story involves the origin of the oceans - where did all that water come from. We might well ask as the dominant theory for some time has been that it was delivered by comets and meteorites.

Megafauna Extinctions

A tale of two theories - both of them inadequate in their own ways. At https://phys.org/print404103492.html ... we have the claim humans wiped out Australian megafauna which just happens to fall hard on the heels of the news that Australian Aborigines  were living in interior Australia between 45,000 and 49,000 years ago (conveniently just prior to the extinction of the megafauna). The paper is in Nature Communications (Jan 20th 2017) but involves some very interesting information about climate as a result of a sediment core off the SW coast (on the continental shelf).
