Ecologic urgency : Air traffic excess

What do you think of that Sean?

Oliver, does the sun push walls?

          Impact on the climate through air traffic

The amount of greenhouse gases emitted during a flight is dependent on two main factors: The amount of fuel burned, and the engine type.

The amount of fuel burned depends on the distance travelled, flight altitude, weather conditions, aerodynamics and the weight loaded. A precise calculation per flight is therefore extremely complicated and not practical. In practice, average values are therefore used to calculate emissions for flights.

Normally the emissions of greenhouse gases per passenger and 100 kilometres are calculated ("100 passenger kilometres"). The emission of CO2 per 100 passenger kilometres is between around 11.6 kg (long haul flights) and 26.2 kg (short haul flights) (Source: ecoinvent). Aside from CO2 , air traffic causes numerous further climate-impacting emissions. Therefore the total impact of air traffic on global warming is higher than that of the effect of the CO2 emissions alone by a factor of around to 2 to 4. In order to take these other climate-impacting air traffic emissions into account, the myclimate flight calculator multiplies the pure CO2 emissions by a factor of 2.

I don't know. I was expecting a warm light (what i call autumn light) and it's a white/spring light.

As you know, for indoor cultivation there are two kinds of lights
which imitates the different lights you get outddor in Spring and Autumn:

The blue one (spring light) and the yellow one that imitates
Autumn, but you told me you never heard of that.

Of course it has to do with the angle how light go through
the atmosphere, the autumn/winter sunbeams are soft and horizontal.

That's why my explanation makes sense: sunbeams are dispersed by the layer of steam water/soot and so the sun is large, white, blazing and has a star shape instead of yellow, round as it has always looked until recently. Now the sunbeam is not really horizontal anymore in Autumn/winter as the beams are dispersed in all directions.



Can you find a recent pic of a very bright star night?
