This article is about conditions during the early Eocene. When I do an SkS search for Eocene, da nada shows up. Do we have a hole to plug? 

How Hot Did Earth Get in the Past? Team of Scientists Uncovers New Information

ScienceDaily (July 5, 2011) — The question seems simple enough: What happens to Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study by researchers from Syracuse and Yale universities provides a much clearer picture of Earth's temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may shed light on what to expect in the future if CO2 levels keep rising.

Does anyone know what climate sensitivity this study would indicate?

Be nice if past 'Greenhouse Earth' preiods weren't so super-dooper hot, makes it easier to reconcile with climate models for starters, and explains how some species were able to exist where their fossilized remains are found.

I can't find a copy of the full paper, but is the abstract suggesting that greater seasonal rainfall is implied by the clumped isotope analysis?

Interesting, I stumbled across WFUWT posting on this. The comments thread reminds me of those chimps from 2001:A Space Odyssey - they have no idea what it means.
