Chemtrails nonsense

[EHocking]

My brother was an air traffic controller on the Nimitz, I'm going by what he says.

So are you claiming that when you pointed to the contrails above your house that;

a. your BiL stated that the lower contrails were at 5000ft and
2. that he declared them not to be mere contrails, but chemtrails? or
c. your BiL picked that the lower contrails were at 5000ft from a photograph and
4. that he declared them not to be mere contrails, but chemtrails?

 

[Dr.Sid]

I think Nimitz must certainly be inside chemtrail business. Ie. whatever that guy says is not true.

 

[EHocking]

The pic I have are ones that are at a pretty high altitude. I can see those being contrails. However, it's when they are only about 5000 feet above your head on a hot sunny day, and persistent, that it becomes questionable. I don't think you can blame atmospheric conditions for condensation in those cases.

Here's the Columbia airport weather forecast for today.

Current Conditions: Partly Cloudy
Temperature: 86° F (30° C)
...
Sky Conditions: Scattered layer at 6000 feet.​

And from Aviation Weather Center, in the afternoon clouds will be forming at 4,000ft.

1400 to 1800 UTC 08 July 2017
Forecast type: FROM: standard forecast or significant change
Winds: from the WSW (250 degrees) at 10 MPH (9 knots; 4.7 m/s)
Visibility: 6 or more miles (10+ km)
Clouds: few clouds at 4000 feet AGL​

So, a hot, sunny day with condensation below 5,000 ft.

You do know what clouds are and how they are formed don't you?

I'll start snapping shots of that kind and posting here just for the benefit of the conspiracy theorists.

Just be sure to date them and also record the weather conditions. (esp. weather at altitude).

I served on two separate Nimitz Class aircraft carriers. I wasn't aware that made me an aircraft vortex density, condensation, and evaporation expert.

Man I learn so much stuff from this board. "Chemtrail expert" is definitely going on my resume.

As an old HR guys the above is too common I would suggest instead:
'Chemtrail information Cloud problem solver-entrepreneur'.

Jodie, you appear to have either missed or ignored the links I posted:

There's a link to a very good site explaining and debunking chemtrails on this very site.

http://contrailscience.com/

The whole thing is based on a dishonest distortion of a hypothetical idea:
http://io9.gizmodo.com/is-that-reflective-cloud-about-to-poison-you-and-change-1638680856

The first one has answers to your questions, here for example, and here.

 

[Jodie]

Do you honestly believe that there is a difference between condensation and condensation? It's the same phenomenon. There's condensation on my toilet reservoir all the time. Stop trying to see sinister meaning in everyday, normal stuff.

Oh please. If it's happening I think it's being done with good intentions. I'm just not sure that it's a good thing in the long run for the environment.

Even so, sheets of condensed expended jet fuel in the atmosphere can't be a good thing.

Did you work in the tower and study meteorology?

That is one day, and we had intermittent thunderstorms yesterday so, of course, it's wrong.

That pic was taken sometime between January and March from the glass bridge that leads from the office to the hospital where I work.

Contrails are not smoke.

You're this far into this nonsense and you don't even know that condensation trails are not smoke trails??

Fuel burns, what comes out is exhaust that forms smoke just like a car on a cold morning. However, car exhaust doesn't leave streams of smoke. If it does then something is wrong with your vehicle.

 

[Jodie]

Why? That's almost a mile high, you don't think this is significant?

The weather at the base of mountains lower than that can be significantly different than the summit.

Today, It's 54 degrees at the summit of Mt Washington, It's 75 at it's base. That's only 4000 feet difference. Should you pack a sweater or do you think it should be OK with what you got at the base?

Contrails only form when it's below a certain temperature. They won't form at 54 degrees, much less the warmer temperatures that we have where I'm living.

 

[Cosmic Yak]

Even so, sheets of condensed expended jet fuel in the atmosphere can't be a good thing.

Persistent contrails are ice clouds, so they are mostly made of ice. They also are likely to contain aircraft exhaust products (including soot and dissolved gases like sulfur dioxide) , but they are overwhelmingly made from moisture condensed out of the surrounding air.

We have a word for small amounts of soot and other chemicals: it's called 'pollution'. No conspiracy needed.

What temperature would that be? Is air temperature the only factor?

How did you determine these trails were produced at 5000 feet?

Air traffic controller isn't a job that involves estimating contrail altitude by eye. Your brother in law doesn't know anything more about it than you do.

This signature is intended to irradiate people.

The aircraft is the same as the car, your car does smoke with water vapor, like a jet, I see it under the right conditions. Yes, like a car on steroids, the Jet engines burns thousands of pound of fuel, and it does pollute. The engines today are much cleaner than the engines in the 60s, in both cars and jets. Your car burns about 10 pounds of fuel an hour, a jet can burn over 1000 pounds of fuel; your car can spread the exhaust from 10 pounds of fuel over 50 miles, the jet spreads the fuel exhaust over 500 miles. Oops, the jet has 1000 times the exhaust, but it carries 200 people over 500 miles, your car carries carries 1 to 5 people one tenth of the same distance. Looks like the jet is only polluting as much or less than your car per passengers mile.

Do you have a point... no, you woke up and finally realized there are contrails from aircraft, something you missed the rest of your life.

You are seeing contrails, not some conspiracy based on ignorance made up by paranoid nuts selling books to paranoid nuts.

Jets and cars both pollute. The jets burn fuel very efficiently, and you don't typically see smoke any more as you did in the 60s. You are seeing contrails, water vapor, just like your car.

So when your kettle boils, there is no steam from it?

Conditions for contrails include both temperature and relative moisture. However, the warmer it is, the more narrow is the window where an engine exhaust can inject enough extra energy into the air to form a persistent contrail. This is the reason they rarely form below altitudes of several thousand meters.

As for more short-lived contrails, you will see them at all altitudes, providing proper conditions. I have seen contrails forming from a plane taking off.
