Absolutely infuriating that university press releases don't include this. They should be embarrassed.
Regarding the actual content, I am no expert, but on surface evaluation their methodology seems generally sound. Importantly, they seem to be referencing data from first hand sources. However, I am still confused. They state:
> A total of 453 measurements were made from 249 individual depth levels on the WAIS Divide Ice core (79.48°S, 112.11°W).
Does that mean '453 measurements from each of the 249 depth levels'? Or '453 measurements from random points in the 249 depth levels'? Or what? And what is the difference between an 'individual depth level' and a 'depth level'.
Such imprecision aside, climate change = warming ocean = wind direction change = catastrophic climate change. I remain worried.
