Wow!
"For more than thirty years, the science has been crystal clear."
Sorry, Ms. Thunberg, but the science has not been crystal clear for thirty years. At least, not the science you're talking about. In fact, IIRC it was about thirty years ago that they were warning that a new ice age was coming -- then, almost overnight, instead of an ice age it became global warming. Then, when that didn't work either, it became "climate change."
And they're still cooking the books.
