The problem is that this is not scary enough for those who are young, because they do not know from direct experience how it was earlier and how it is today.
I am old enough to remember that when I was a child, where I live, in Europe, every winter there was permanent snow coverage since early December until late March.
On the other hand, in the last 10 years there was no more than a week of snow per winter, and in the last 5 years no more than a couple of days with snow per winter.
There are more than 10 years since I have used for the last time my winter clothes and boots.
Such a big climatic change in less than a human lifetime cannot be ignored and it is not at all certain how it will evolve and which will be the consequences.
