The Age Of Disinformation

I couldn’t resist posting this article at Medium by meteorologist James Spann, pretty much because of the title, although he makes a very good point about modern news communication:

I have been a professional meteorologist for 36 years. Since my debut on television in 1979, I have been an eyewitness to the many changes in technology, society, and how we communicate. I am one who embraces change, and celebrates the higher quality of life we enjoy now thanks to this progress.

But, at the same time, I realize the instant communication platforms we enjoy now do have some negatives that are troubling. Just a few examples in recent days…

I would say hundreds of people have sent this image to me over the past 24 hours via social media.

Comments are attached… like “This is a cloud never seen before in the U.S.”… “can’t you see this is due to government manipulation of the weather from chemtrails”… “no doubt this is a sign of the end of the age”.

Mysterious Anti-electron Clouds Inside Thunderstorm

DURHAM — A terrifying few moments flying into the top of an active thunderstorm in a research aircraft has led to an unexpected discovery that could help explain the longstanding mystery of how lightning gets initiated inside a thunderstorm.

University of New Hampshire physicist Joseph Dwyer and lightning science colleagues from the University of California at Santa Cruz and Florida Tech describe the turbulent encounter and discovery in a paper to be published in the Journal of Plasma Physics.

In August 2009, Dwyer and colleagues were aboard a National Center for Atmospheric Research Gulfstream V when it inadvertently flew into the extremely violent thunderstorm—and, it turned out, through a large cloud of positrons, the antimatter opposite of electrons, that should not have been there.

To encounter a cloud of positrons without other associated physical phenomena such as energetic gamma-ray emissions was completely unexpected, thoroughly perplexing and contrary to currently understood physics.

Around The World, Clouds Sinking Closer To Earth

cloudsThe sky really is falling, Universe Today reports:

According to recent research by climate scientists in New Zealand, global cloud heights have dropped. Researchers reported a decreasing trend in average global cloud heights from 2000 to 2010, based on data gathered by the Multi-angle Imaging SpectroRadiometer (MISR) on NASA’s Terra satellite. The change over the ten-year span was about 100 to 130 feet.

“This is the first time we have been able to accurately measure changes in global cloud height and, it provides just a hint that something quite important might be going on,” said lead researcher Professor Roger Davies.

Heat Wave Due To “Exceptionally Strong” Air Mass

Today has been the coolest day all week in the Northeast of the US.  The Midwest, Northeast and Southern parts of the country have been experiencing consecutive days of high temperatures and humidity which have contributed to many deaths throughout the country. What is the cause of this cantankerous heat and is it an indication of future affects of global warming? The National Geographic reports:

A stubborn high-pressure system is the culprit behind the dangerously high heat wave that’s been baking much of the U.S., experts say.

The high-pressure system—a large area of dense air—is being held in place by upper-level winds known as the jet stream. Within the system, dense air sinks and becomes warmer, and since warm air can hold more moisture than cooler air, there’s also very high humidity. (Learn more about Earth’s atmosphere.)

Stationary high-pressure systems aren’t unusual during the summer, according to Eli Jacks, a meteorologist at the National Weather Service headquarters in Silver Spring, Maryland.
