Debunking Conspiracy Theories – Chemtrails – Pt. 2–Why do some contrails last longer?

So, to continue what I started on June 24 – (not even three full months ago ) – I now return to the Chemtrails conspiracy. Last time together we took a look what are Chemtrails really.

To summarize quickly, just in case you are not interested in visiting the part 1., aircraft do leave trails behind. But they are actually a phenomenon that occurs when the byproducts of burning the aircraft fuel mix with cool air. The process of burning aircraft fuel leaves behind carbon dioxide and water. So, there is water vapour in the engine exhaust. This means that water droplets can form. How? Well, in essence, hot and humid air exits the engine. This is kind of like when you breathe out hot air from your lungs into the cold air outside. What happens? You provide moisture to the air, so condensation happens. This is not the whole story, as the contrail freezes in the cold air. By cold air it’s usually meant below -30°C. When you have air that cold, that means that those water droplets freeze very quickly. So, you now have ice particles. This is what the contrails are made from.

Debunking Conspiracy Theories – Chemtrails – Pt. 1 - What are they really?

There are two distinct schools of thought when it comes to crazy conspiracy theories. First school of thought basically says that they should not be even discussed because it gives crazy, deluded or simply hopelessly ignorant people a platform to stand on, brings them into the mainstream and validates them. In other words, this school of thought feels that the very act of talking about these theories, somehow hints that we should take them seriously.

Why should we Trust Science?

if you think about it, it’s actually pretty sad that somebody is even motivated enough to open a Word processor and start writing about why should we trust science. Make no mistake, it’s important to think for yourself and not blindly follow what any authority says, but in this day and age, we all can agree that the problem of our World is NOT too much rational thinking and looking at the evidence, but rather the opposite. It is not that people are looking for evidence and then look at the evidence themselves, it’s that people are looking for opinions that confirm their already existing suspicions or preconceived notions. That is called Confirmation Bias.

Look up from your phone and see that there are problems in the World

Sometimes I feel the world really needs a reminder that it has problems, so I'm going to spell out a few of them here. Generally it helps if you have problems spelled out, as humans tend to forget what things are important and just focus on the newest, shiniest phones and apps. Even as a developer, I must admit that apps are not going to change the world. Not really. Not in any REALLY, I mean REALLY important way.

OK, this was a gross generalization, as our precious phones and apps all help us to lead better and more comfortable lives in some way. You can connect with your long-lost friends. You can send messages to people more cheaply. Of course, sometimes these wonders of technology will save somebody's life. This is all great. But I sometimes feel that humanity in general has lost sight of the fact that there are REAL, bigger problems in the world.
