I don’t blame Greta Thunberg for the fact that her prediction from 5 years ago turned out to be wrong. What I do blame her for is that she has not displayed enough intellectual curiosity to try to find out why her prediction was wrong.

It’s OK to be wrong about something. It’s OK to make predictions that turn out to be false.

But a good scientist will try to learn why they made the mistake. A good scientist will try to learn why their prediction was wrong.

This is a dead link to a tweet that Greta Thunberg made 5 years ago. The reason the link is dead is because she deleted it:

https://twitter.com/GretaThunberg/status/1009757391515156480

Fortunately, the Internet Archive has an archive of the tweet at this link:

Her tweet from 5 years ago says:

“A top climate scientist is warning that climate change will wipe out all of humanity unless we stop using fossil fuels over the next five years.”

This is a screenshot of how the archived version of her tweet appears on my computer screen:

Like I said, it’s OK to be wrong about something, and it’s OK to make predictions that turn out to be false.

However, by deleting her tweet, instead of trying to learn why her prediction was wrong, she is showing a complete lack of scientific curiosity.

And that is wrong.

Science is all about learning from past mistakes.
