I suggest that we track down news sites which relay the news without explanation, and often with surprise or even disbelief. For example this is a translation of a French tech news site :
Fortran is now back in 20th position, which makes it more popular than languages like Objective-C, Scratch, Transact-SQL, Rust or Kotlin!
This revival of popularity is however difficult to explain even if the pandemic has, as in the case of COBOL, often reminded administrators of the harsh reality of the technical debt and of the quantity of ancestral programs still running in a corner, sometimes forgotten by all.

Another French site says:
This surprising return can be explained by its ability to facilitate massive calculations, especially for scientific calculations.
which says nothing, as there is no reason for a surge in massive calculations from one year to the following. Although it is not false, since it is the reason we are here.
Another site finally asks:
How do you explain the return of Fortran to the top 20 most popular programming languages?
and I posted a message in their forum with some explanations. At least this site does not just express prejudice, but asks its users to express themselves.
Most of those sites just relay the TIOBE news, without inquiring further. We could post there some comments about the Fortran-lang.org community, whose frenetic activity on the web for one year can not be unrelated to that revival.
