Notwithstanding all the over-the-top thespian histrionics, it achieved the massive media attention she craved, and her message is important.
But I also found it very uncomfortable viewing.
Greta has Asperger syndrome, a form of autism that she calls her ‘superpower’.
It’s a developmental disorder characterized by profound difficulties in social interaction and nonverbal communication.
It can cause those who have it to develop an ‘intense preoccupation with a narrow subject’ and ‘one-sided verbosity.’
People with Aspergers have feelings like pain and fear, and joy, but often experience them far more intensely than by those who don’t have it.
It would be hard even for her most ardent supporters to argue that Greta doesn’t currently have ‘an intense preoccupation with a narrow subject’ or that she displays a ‘one-sided verbosity’.
Or, indeed, that her constant highly emotional apocalyptic warnings that the world’s exploding into hell all around us, are not perhaps driven with abnormally enhanced fear and pain.
She’s quite clear too that she wants fellow teenagers to share that fear and pain.
And that’s where I have a problem with Greta.
On the science, I agree with her: climate change is a very real and present threat and our world leaders must all do more to combat it.
But her end-of-the-world-is-nigh ranting rhetoric is terrifying millions of young people to an extent that eco-anxiety is massively increasing as a stress disorder.
To put it bluntly, Greta’s made almost her entire generation think they’re about to die.
And she doesn’t really have any answers for what they can do about it.
Asked by a journalist from The Atlantic this week what young people like her should actually DO to combat climate change, she replied: ‘They can do everything. There are so many ways to make a difference.’
Sure, but specifically what?
When pressed, she suggested joining an activist movement and if you’re old enough, voting.
Well yes, that much is obvious.
But Greta doesn’t have much else to offer the debate; she just wants us to ‘listen to the science’.
