The signal of: fasten your seat belt,
It’s on for the whole flight and the hostess even mention to bring you a snack or a welcome drink.
You are not on a low-cost flight with a tyrant pilot, you’re in 2050 and here… here frolic all around .
Bruce Carmichael, director of the Aviation Applications Program:
“the danger concerns damage to people, especially to the crew, because the flight attendants are usually not fasten, they could be tossed inside the cabin”.
Bret Jensen, a spokesman for Boeing said:
“aircrafts are designed to withstand without damage to forces of 2.5 G and 3.5 G forces before suffering structural failure”.
What will happen in the sky and during air travel is easy to say, the frequency of moderate to large turbulence will increase by a percentage between 40 and 170 per cent by 2050.
Even the guilty is easy to say, it’s CO2 emissions into the atmosphere.
But first things first.
The research at the University of Reading, which was published in the journal Nature Climate Change, shows that the increase of CO2 in the atmosphere profoundly alter the stability of the current in height.
The impact on our comfort during air travel is not the only negative consequence, we get almost inevitably to the increase of 2°C of global average temperature, and at this rate we will arrive at 5. Already now, natural disasters, torrential rains, tornadoes and landslides are the most immediate consequence of the damage causing by greenhouse gases, but without a brake, not even Noah’s ark will be a hope.
The zoom on the last century and the Keeling curve of the last fifty years, highlight the trend of increase in the concentration of atmospheric CO2 that led from 280 ppmv (parts per million by volume) pre-industrial era, to the current 368 ppmv .
In other words, it is human activity that boosted high the concentration of CO2 in the air, with the consequences that we see from under an umbrella or shelter with a factor 50 .
Coming back to the aircraft, ahi them, the turbulence that they will face is caused in large part from them as well, because of their voracious consumption of fossil fuels, and therefore, due to their high greenhouse gas emissions.
Orville Wright explained that the reason why a plane flies: “the aircraft remains in the air because they do not have the time to fall”.
To not “have time to fall”, a plane, use the fuel that weighs even more than 70% of the total weight of the aircraft, and it is this fuel that causes pollution.
To overcome the turbulence need more power, so more weight because more fuel, and therefore more pollution.
Waiting to see an electric plane or maybe launched by a giant slingshot, I follow the example of my teacher of physics in high school (ntl prof. Fiorio) : ” … when they talk about global warming, I go out with an umbrella”.
Oh, and as he expected, I await your response after the summer holidays.
