Origin of global warming

It seems that the weather is getting warmer because of pollution. Airborne particles act as a kind of lid around the earth. The sun hit the earth, the earth heats up, the heat can not escape because of the pollution lid, the temperature increases. I'm a little bit surprised by this magical lid that lets heat pass in one direction and not the other.

I am also very surprised because the majority of the planet is covered by oceans. So the pollution lid is not very tight. It is mostly concentrated above big cities. How can heat end up trapped by a lid with such wide holes?

One day as I was leaving my workplace, I looked at the huge building from afar. I thought about the dozens of wireless networks that it contains, the thousands of laptops also fitted with WiFi connection, the thousands of mobile phones owned by the employees, that antennas that shower 4G upon us, the hundreds of flat screens that broadcast news continuously ... I thought about the staggering amount of microwave that we must enjoy every day to earn our wages. I thought that working in such a building was akin to working into a microwave oven. But instead of being cooked within a few minutes, we simmer gently for several years.

The other difference is that the microwave oven is supposed to be sealed whereas the building is made of concrete, metal and glass, therefore the waves escape from it. It was raining a bit that day. I thought that all these microwaves were likely to heat the air humidity. Suddenly I thought of all the waves that surround us globally. What if that was the actual magic lid that heats the planet?

Unlike chemical pollution which is relatively local, which is heavy, which tends to fall to the ground when the air is cold and moist, microwaves cover the whole earth and they constantly stir the air day and night. Let's review the various sources of large-scale waves.

Let's start with the small wave sources. We are billions to own a mobile phone and devices fitted with bluetooth or WiFi connections. We are millions to have Internet at home with a WiFi set top box. We are billions to own a cathode ray or flat television screens. Whenever we use these appliances, we send lot of waves in the air.

For the sake of convenience, many people leave these devices plugged in or turned on even when they don't use them. Our individual equipments therefore generate large amounts of waves. The waves heat the matter and especially water. The proof of that is that the specific absorption rate (SAR) of mobile phones is determined by measuring the temperature of a liquid-filled devices. The proof of that is that when we use the phone for too long, our temple becomes hot. The proof of that is that we cook this way, ie by using microwaves to heat the water inside of the food. Microwaves heat the water, we all know that. A device that emits microwaves in the open, it's meaningless. But what about billions of devices 24 hours a day?

Let's have a broader vision. Waves are also used in a collective way. Radio stations broadcast music through waves scattered on a large scale, the signal is picked up and repeated at regular intervals. One of the radio waves broadcast principles is that they bounce off clouds and can be thus disseminated further. TV also works along this principle. Although the signal format is now digital, television shows are still transmitted to us through the air, thanks to waves that are calibrated so as to shower upon whole countries. The cities and countrysides are lined with antennas for our dear mobile phone to get signal, even in the most unlikely places. The mobile phone also made a major breakthrough in developing countries, so the cities just like like the country are covered all over the globe.

This is a domestic collective use of waves. What about the industrial, scientific and military ones? They are also certainly making intensive use of air broadcasts, so equally intensive but more confidential.

Let's go further. As far as I know, it is the satellite that floods us most with waves. We are impressed when we see images of the earth taken by satellites but do we think about the price to pay? In order to let us enjoy these pretty pictures, a spacecraft massively bombed the earth with waves, every single inch of land is targeted. Some parts of these waves were absorbed by water, by the soil, by objects, by living beings. Some other parts bounced so violently that they returned back to the spacecraft. Using computer programs, the machine interpreted the waves that it picked back and synthesized realistic digital images of the earth.

There are also satellites for television, for the Internet, for mobile phones, for the weather, for location, for science and war... The first satellites were launched in the 60s. Since then almost 7000 spacecraft were thus put into orbit! In the next few years more than 1,000 additional satellites will be sent into space. Each of them pours forth waves upon the earth day and night until it reaches the end of its life.

Honestly, if microwaves heat the water then let no one tell me that this wave profusion has absolutely no effect on the atmosphere and especially on its moisture. The types of devices are so various that all frequencies are extensively covered. Maybe chemical pollution also plays a role in global warming but I am convinced that it is meaningless compared to the effects of waves.
