By way of Watts Up With That comes something I noticed in one of the comments that I hadn't seen before but was totally appropriate . In this case it's an acronym. I have no idea if it's new or has been around a while, but I haven't come across it before.

In the case of the WUWT post I was reading, the commenter was suggesting that some numbers about the CO2 levels that will exist in the year 2100 were “POOMA” figures.

What is a POOMA figure?

Pulled Out Of My A**.

I find that to be perfectly appropriate.
