Weather balloons

We read it very early on
As the hole in ozone bloomed
NASA in Alaska with their weather balloons
They captured all the data
And when it was not what they assumed
They said it must be calibration
The gadget out of tune.
So they put it back to benchmark
Light made dark by folk so smart
We'd just been to the moon.

And throughout the 70s
And in the 80s too
They threw out what they saw
For what they thought they knew
We sprayed aerosol and CFCs
The hole above us grew
And all the while they changed the spreadsheets
Thinking them untrue
And these were folk of science
They were not buffoons
Whole teams for decades
Deaf to weather balloons.
