Every snowflake needs a dust cut!

the climate in the world has a constant: it is constantly changing. Humans are contributing things to their own hands, although in different ways. A recent study confirmed studies from the previous time: ever more clean air ensures less harsh winters! The study comes from scientists from the California Institute of Technology. They remember the tighter winter during and especially after World War II; The European continent had to be completely rebuilt, especially Germany, where it became the famous economic miracle. That did not mean, however, that industrial production boomed extremely. And from the shades came clean dirt, filters were not there yet, or had no priority.

The air was trapped by so-called aerosols; they absorb sunlight and contribute to the formation of more clouds in the sky. And that would be the explanation for the really cold winter in the 60’s and 70’s. Then the western industrial nations started putting filter systems on the fireplaces, the cars got a catalyst, the heaters became more efficient, etc. With the fall of the Berlin Wall, the industry in the former Eastern Bloc was slowly renewed and even more environmentally friendly.

less concentration on aerosols, less clouds, more sun. The American scientists from the California Institute of Technology do not refute the theory of greenhouse effect, but see a complementarity here. And they come to a shady conclusion: in Europe, meanwhile, the air would be so clean that little progress could be expected. And that would mean that, due to the old continent, no longer could be expected with further mention. However, the situation in the northeast of Asia remains diminished.

Less dust in the atmosphere also means less snow, provided the temperatures are low enough. On Wissen.de it reads as follows:

“In order for snow to form, the air must first contain sufficient moisture. If water molecules then accumulate on so-called crystallization nuclei – for example small dust particles – and start to freeze, ice crystals form. ”

To all of us who are not scientists, we have to make an opinion about all that. Not so easy!
