What the source says
The published abstract says that northern ice sheets keep temperature and carbon dioxide low through a glacial, that carbon dioxide falls to about 200 parts per million, and that the resulting dust darkens the ice so that the next rise in northern sunlight melts it. This record does not copy the paper.
Why it is here
It is the paper the journal article of the same title is describing.
Ralph’s interpretation
Ellis has also said, in plainer words, that carbon dioxide is only a small player and that dusty ice sheets are the main feedback. That wording is his summary, not a sentence from the abstract.
Alternative readings
The abstract says the standard Milankovitch-precession theory does not explain the long intervals between interglacials. The proposed mechanism is the authors’ hypothesis. It is not an established scientific consensus.
