I took the above photo today. It shows some Cumulus mediocris clouds. Medium sized cumulus. There are some people who think that these small fluffy clouds are the only type of "real" clouds that exists, and that high clouds such as cirrus or odd looking clouds like mammatus are evidence of some kind of global plot to modify the climate. Less extreme, but still overly suspicious, folk think that there are new clouds that exist in addition to the ten they were taught at school.

This suspicious was no doubt compounded when the World Meteorological Organization announced last week that the International Cloud Atlas was being modified to include...

Last year I created a physical model to illustrate some aspects of the WTC Tower collapses. The basic structure was columns connected by floors. The floors supply lateral stability to the columns, so when the floors are removed the columns are very unstable. This worked out reasonably well, and I got this nice demonstration from it:

I'm currently re-creating my physical model as a virtual model using Blender physics to allow for a larger variety of experiments, and also to illustrate the difference that scale makes.

The first version I tried quite...

This image has been circulating on social media and "tabloid" news sites, with claims that it shows a "human shaped cloud" or ghost hovering above a Zambian shopping centre:

The photo is actually clearly a photoshopped creation using this photo of a kite (the strings...

The video of a Jet Airways flight being intercepted by German fighter jets is causing a bit of interest on social media, both due to the very visible contrails (enhanced by the video being filmed near sunset) and by the appearance of a "UFO":


Source: https://www.youtube.com/watch?v=iJALftSN0ek

Flight 9W118 from Mumbai to London on February 16th 2017, a Boeing 777, was intercepted after it failed to respond to air traffic control on the correct frequency over Germany.

The video was shot from a British Airways 777 flying behind it and 2,000 feet higher (flight BA2042).

The "UFO" appears to fly from left to right (and slightly "forwards", ie towards the same direction as the filming plane rather than perpendicular) from around 1:26 in the video:

Multiple fake news and clickbait sites are repeating variations of a story that FEMA expects the Oroville dam to collapse, killing thousands of people. This story is false. The source quoted is KCRA:
http://www.kcra.com/article/fema-su...ce-base-in-case-of-oroville-emergency/8944641
Perhaps the most obvious clue there is that only "two dozen" personnel have been deployed. Not a lot for the "worst disaster in American history".

But the facts...

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:...

An odd theory floating around the internet is that one of Trump's secret service agents has fake hands, and is actually holding some weapon under his coat with his real hands. The evidence given for this is that the agent holds his hands in the same way for long periods of time.

He doesn't have fake hands, in fact you can see his hands move:

But he does hold them like that a lot:

(Even in the above you can see he does change hand positions, his thumb in particular.)

But what's up with the guy and the stiff hand position? Well it's actually a core...

When I first saw this it was nearly horizontal, and looked, if not a flying saucer, then at least like a flying plate viewed edge on. It's a distant sunlit contrail, often mistaken for UFOs, space junk, or meteors. So I thought it would be useful to get a sequence of photos and video at different zoom levels.

The video above is unedited, zooming from 24mm to 2000mm.

The sequence of photos are all straight from the camera, except the first where I've called out the trail as it's hard to see.

Chilean Navy UFO Metabunk 3.

If you are short on time, then I made a one minute video explaining this:

Background: Infrared footage from the Chilean Navy appears to show some kind of flying object that briefly leaves a trail behind it.
