Journal ArticleDOI
Trends, Rhythms, and Aberrations in Global Climate 65 Ma to Present
TL;DR: This work focuses primarily on the periodic and anomalous components of variability over the early portion of this era, as constrained by the latest generation of deep-sea isotope records.
Journal ArticleDOI
An early Cenozoic perspective on greenhouse warming and carbon-cycle dynamics
TL;DR: Past episodes of greenhouse warming provide insight into the coupling of climate and the carbon cycle and thus may help to predict the consequences of unabated carbon emissions in the future.
Journal ArticleDOI
Target atmospheric CO2: Where should humanity aim?
James Hansen,Makiko Sato,Pushker Kharecha,David J. Beerling,Robert A. Berner,Valérie Masson-Delmotte,Mark Pagani,Maureen E. Raymo,Dana L. Royer,James C Zachos +9 more
TL;DR: In this paper, the authors show that the current CO2 level can be reduced to at most 350 ppm by phasing out coal use except where CO2 is captured and adopting agricultural and forestry practices that sequester carbon.
Journal ArticleDOI
Rapid acidification of the ocean during the Paleocene-Eocene thermal maximum.
James C Zachos,Ursula Röhl,Stephen A. Schellenberg,Appy Sluijs,David A. Hodell,Daniel Clay Kelly,Ellen Thomas,Ellen Thomas,Micah J Nicolo,Isabella Raffi,Lucas Joost Lourens,Heather K McCarren,Dick Kroon +12 more
TL;DR: Geochemical data from five new South Atlantic deep-sea sections indicate that a large mass of carbon dissolved in the ocean at the Paleocene-Eocene boundary and that permanent sequestration of this carbon occurred through silicate weathering feedback.
