Can you tell us in a few lines why it matters and what is the mechanism through which the contrails have an impact on the climate?

Yes, exactly.

So if you look up to the sky, you might see an aircraft generating a trail, so a white trail.

Not necessarily all the time, but sometimes they do.

And in some cases, those contrails, which contrail actually stands for condensation trail, right? They persist.

So under certain atmospheric conditions, there's like a long line that remains behind the aircraft.

And ultimately, this cloudiness just might merge and develop into a natural cloudiness.

But how do you see things going in, yeah, as I mentioned, in the next three, five years, let's say?
