Soils comprise the largest terrestrial carbon (C) pool, containing both organic and inorganic
C. Soil inorganic carbon (SIC) was frequently disregarded because (1) it is partly heritage …

Ocean acidification may have severe consequences for marine ecosystems; however,
assessing its future impact is difficult because laboratory experiments and field observations …

The geological record encodes the relationship between climate and atmospheric carbon
dioxide (CO2) over long and short timescales, as well as potential drivers of evolutionary …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

C4 photosynthesis is a series of anatomical and biochemical modifications that concentrate
CO2 around the carboxylating enzyme Rubisco, thereby increasing photosynthetic efficiency …

Paleosols (fossil soils) are preserved throughout the geologic record in depositional settings
ranging from alluvial systems to between basalt flows. Until recently, paleosols were studied …

Paleoclimate data show that climate sensitivity is~ 3 deg-C for doubled CO2, including only
fast feedback processes. Equilibrium sensitivity, including slower surface albedo feedbacks …

Background The soil represents a reservoir that contains at least twice as much carbon as
does the atmosphere, yet (apart from 'root crops') mainly just the above-ground plant …
