A video is being widely shared on social media (and the "weird news" sections of more traditional media) claiming to show the image of an impossibly large city rising above the fog in the city of Foshan (佛山), Guangdong province, China
Here's a composite image of the Foshan video
Notice the scale of things here, there are what looks like two construction cranes on the "horizon" to the left, and the buildings seem to loom high into the sky above them.
Interesting sunrise contrail, not sunset like most of this type of thing. Less commonly observed, mostly because people are still in bed. Here the contrail develops in sections as it passes through bands of moisture. You can see those bands of moisture reflected somewhat in the bands of cloud (although the clouds are probably not at the exact same altitude).
It actually is a translucent disc hovering over a storm cloud. It's a type of cloud know as Pileus, or a cap cloud, which is formed above a cumulonumbus cloud (a storm cloud) by the strong updraft. Seeing a pileus cloud indicates that the storm cloud is growing rapidly. Source
In the classifications of causes of death shown in the chart above, CLRD (the red line) is "Chronic Lower Respiratory Disease", which is a combination of bronchitis, emphysema, and asthma. CLRD is currently the third leading cause of death in the US, moving from 4th to 3rd in 2008.
However the actual rate of CLRD is largely unchanged from 1999, actualy moving down slightly from 44 deaths/100,000 in 1999-2001 to 42 in 2011-2013. So there is no rise in respiratory mortality. The reason CLRD "overtook" stroke in 2008 was because the rate of deaths from stroke is decreasing faster than deaths from CLRD. Let's compare just stroke and CLRD:...
Scientist J. Marvin Herndon Recently published two papers that argued that there's a secret climate modification program being carried out worldwide involving loading ash from coal power stations into planes, and then spraying it into the upper atmosphere to block the sun.
Update: the second of these two papers has been retracted by the publisher
The evidence he presents is essentially taking a rough chemical profile for dirt or ash, and then testing dirt (dust or soil in air and water), and then noting that the profiles are similar within a huge range of possible values. This is fairly standard stuff in the "chemtrail theory".
But the really interesting thing is that Herndon's papers, which have been lauded by the...
A photo of a statue with what looks like a QR code for a face has been making the rounds on social media, with some of the more imaginative people suggesting that it's evidence of ancient aliens.
The "ancient aliens" would also have to be time traveling aliens, as QR codes were only invented in 1994. So the most likely explanation is that it's a modern statue. Either an ironic work of art, or some kind of marketing thing - possibly the company identified in the QR code sponsoring an exhibit.
I took a few minutes to transcribe the QR code into machine readable format, and then scanned it. The result was rather boring:
The following statements were made by Patrick Roddie in a statement he read at an EPA public comment hearing on greenhouse gases in aircraft exhaust. Roddie is a proponent of the "chemtrail" theory, thinking that persistent contrails are actually something toxic being secretly sprayed by the US government. Roddie was recently featured in an SF Weekly article on the chemtrail theory.
This is an excellent example of a contrail edge shadow in Italy. Edge shadows happen when a part of a contrail is lined up with the sun (from the point of view of the observer). This creates a slab of shadow through the haze, and the observer sees it edge on, so it looks like a dark beam extending in front of the contrail, often down to the ground. The curved section (and the straight section to the right) is still leaving a shadow, but because the camera is not lined up with it and the sun, you can't see it.
