I'm sorry but I don't actually believe that she has Asperger's syndrome. It is my opinion that her handlers dreamed up and released that story to the media in order to garner empathy for her and to dispel the rising tide of doubt about this girl's veracity, in an attempt to silence her detractors. Even so, as @ItIsFinished! says, her having Asperger's is absolutely no excuse for her vitriol. I totally agree with everything that he says.@Berni
This young person has Aspergers syndrome, as you will know, and it is characteristic of such that they become focused on a particular subject of interest, becoming completely absorbed by it. This is what has happened to this young person. Yet the subject of global warming is not a fiction, it is a fact, being proved by major meteorological events, worldwide: such as major fires and floods, storm surges and so on. Water levels are rising and the dangers cannot be ignored.
Seeing children rising up and leaving their schooling to protest in the streets is something I find disturbing: for it encourages rebellion and social unrest at an early age. Yet the refusal of some to acknowledge the warning signs, and bury their heads in the sand is also disturbing.
A reading of the Old Testament and the rules laid down in relation to the land, with opportunity given for it to 'rest' periodically, makes it obvious that God is concerned that we take care of the earth that He has created. In Revelation 11:18, we are told that God will finally destroy those who destroy the earth. Warning is also given concerning meteorological and geological changes which will take place in the last days of this dispensation in Matthew 24:3-8, which we must not ignore.
In Christ Jesus
It is my experience of young people who actually DO have Asperger's, that they are extremely intelligent, they do indeed have compulsive obsessions. However, these obsessions are normally short lived, their attention spans can be extremely finite. Indeed, one of my young friends, with Asperger's, certainly moves on to his next compulsive subject on an almost weekly basis.
