Watch "Last Extinction" Online
After screening on PBS in America in March, the 1 hour documentary “Last Extinction” is now available for viewing online:http://www.pbs.org/wgbh/nova/clovis/program.html
The doco investigates the possibility of a comet causing widespread large mammal extinctions 12,900 years ago. Currently the most academically accepted theory is that migrating humans hunted the megafauna to extinction. However recently discovered evidence suggests that a comet may have struck at that time:
Earth’s temperature, according to geologic records, dropped 18 degrees in two years
Scientists found iridium, rarely found on earth, in elevated levels across Northern America. Iridium is often an indicator of meteors and comets, and was also found in the layer correlating with the extinction of the dinosaurs 65 million years ago.
Found alongside the iridium were hexagonally shaped microscopic diamonds, which don’t occur naturally on earth
All that stops this theory from becoming scientific fact is the lack of a crater, (although this hasn’t been the case with Tunguska…). …
I’m Stumped by this Chinese Geoglyph
Originally posted by myself at 2012Forum.com, and nobody could tell me what it really is, so I’m asking the audience of this blog for ideas…
AstralWalker’s talk in Melbourne last month had some slides about GeoGlyphs. It was interesting hearing all the gasps in the audience when he showed the Chinese pyramids…
But this, I have not seen before:http://www.gearthhacks.com/downloads/map.php?file=20423
It is in China, near the Mongolian borderIt is big – looks like hills etc don’t get in the way
The difficulty in determining what it is comes from the huge range of existing geoglyphs, that range from modern art like Colonel Sanders and the Firefox logo, to the ancient Nazca Lines. Without inspecting them at ground level, it is very hard to determine age and technique.
The best suggestion at the forum was that this is something like a quarry, and a large grader was used by someone who was on more then just a …
Solar Cycle Will Be Weakest…Or Not?
It wasn’t very long ago that we were being told to brace for, in 2012, the biggest solar maximum for some time. Now some scientists are predicting that it will be “the weakest since 1928“.
The panel now expects the sun’s activity will peak about a year late, in May 2013, when it will boast an average of 90 sunspots per day. That is below average for solar cycles, making the coming peak the weakest since 1928, when an average of 78 sunspots was seen daily.
So there’s nothing to worry about, except:
“The panel consensus is not my individual opinion,” says panel member Mausumi Dikpati of the High Altitude Observatory in Boulder, Colorado.
Dikpati and her colleagues have developed a solar model that predicts a bumper crop of sunspots and a cycle that is 30% to 50% stronger than the previous cycle, Cycle 23.
Such disparate predictions are similar to the global warming debate. …
2012 Countdown Now Mainstream
The above widget was found at the South Florida Sun Sentinel – a great example of how commonplace this meme now is!
