NASA atmospheric observations only confirmed the ground-based measurements of stratospheric ozone depletion over Antarctica in the southern hemisphere spring (October). In fact, the data analysts originally thought the data was erroneous -- they had to get the ground-based measurements to confirm that the satellite data wasn't wrong.
That's not how I remember it being "sold". I don't doubt that the science is valid for that particular "snapshot", but
NASA went overboard in pimping itself as envirowacko for funding - the Algorists.
