Engulfed America? Should we get tested?

Wouldn't be the first time.

"Military Once Used SF Fog For Simulated Germ-Warfare Attack, Exposing 800,000 To Harmful Bacteria"

SAN FRANCISCO (CBS SF) -- In what sounds like a conspiracy theory, the fog over San Francisco was used by the U.S. military in the 1950s as a way to maske the spreading of a biological agent in simulated germ-warfare attacks.

Leonard Cole, the director of the Terror Medicine and Security Program at Rutgers Medical School, called it one of the largest human experiments in history.

For a period of 20 years between 1949 and 1969, the U.S. Army conducted more than 200 secret biological warfare tests over populated areas. Among the first was in the 1950s along San Francisco's bay coastline.

A Navy minesweeper went back and forth for a couple of days in September spraying a bacteria called Serratia marcescens in a mist that was unnoticed due to the region's fog.

In his book, "Clouds of Secrecy," Cole said it was touted as harmless bacteria, but that wasn't the case.

Nearly all of San Francisco received 500 particle minutes per liter. In other words, nearly every one of the 800,000 people in San Francisco exposed to the cloud at normal breathing rate (10 liters per minute) inhaled 5,000 or more particles per minute during the several hours that they remained airborne.

Cole said a careful inspection of the medical literature would have shown that bacteria was responsible for not only making some people ill over the course of 50 years, but also in a few instances caused their death.

"Here's an experiment involving human subjects, but the purpose of the experiment was not to see anything about the survival of the individuals," Cole said.

There are basically two measurements relevant here, temperature and what is called dew point. Both are measured in degrees F or C.

On a normal day, the temperature drops at a fairly constant 2 degrees per 1000 feet of altitude. So if the temperature is 80 degrees, and the dewpoint is 76, you will see clouds forming at 2000 feet.

We call it fog, but fog is basically a cloud sitting on the ground. It occurs when the temperature and dewpoint on the ground get very close to each other, say within a degree or so, or match. There ate a variety of different names for types of fog, buy these have to do with the different geographic factors that cause the tempetature and dewpoint spread to come together.

Once it forms, fog needs something to happen to make it go away. Typically, the sun comes up, the temperature goes up, and it disappates. So just like you can predict its formation, you can anticipate it disappating. A naturally occuring fog should not disappear unless the conditions that caused it to form reverse themselves.

We had a fog event here a few weeks ago. It formed around 6pm and had disappated by midnight.

It formed when the temperature/dew point spread was 2 degrees and the relative humidity was 95%. The wind speed was around 8 miles an hour. From its formation to its disappation, the temperature/dew point spread decreased to 1 degree, the relative humidity went up slightly, and the wind speed went down to 4 mph without changing direction.

Airports 50 miles north and south were reporting clear skies.

This did not behave like a naturally occuring fog.

Two days later we had a naturally occuring fog event that set in at night and butned off in the AM with the spread starting at 1 degree and dropping to 0.4 degrees over the course of the night.

I would be interested in seeing the lab reports.

This is an example of pattern recognition biasseeing something unusual and assuming external manipulation rather than natural variability. Have you considered evil spirits being behind this?

This has nothing to do with "pattern recognition", but rather a scientific analysis of why fog forms and why it disappears. Since you seem to think that there are 666 genders and spending hundreds of millions of dollars transing animals is "science", it's understandable that you wouldn't recognize real science.

I think there are two genders. I like animals more than humans and certainly don't condone the testing.This called a straw man fallacy. Generally a fallacy used by people that don't understand what they are talking about

Someone who remembers HS Science. Thanks! My memories are more of getting bored and dozing off
