Global Carbon Cycle and Global Warming
"... This Report first outlines our generic Data-Based Mechanistic (DBM) modelling philos-ophy, in which models are only deemed credible if, in addition to explaining the time series data in a statistically efficient, parsimonious manner, they also provide an ac-ceptable physical interpretation of the sy ..."

-sumptions and paradigms of the scientist and model builder. The Report then goes on to consider the problem of modelling the global carbon cycle; a problem that has great relevance in the current debate about global warming. Using the DBM approach, we identify a simple stochastic differential equation model that includes

Authigenic carbonate and the history of the global carbon cycle
- Science
, 2013
"... We present a framework for interpreting the carbon isotopic composition of sedimentary rocks, which in turn requires a fundamental reinterpretation of the carbon cycle and redox budgets over Earth’s history. We propose that authigenic carbonate, produced in sediment pore fluids during early diagenes ..."

diagenesis, has played a major role in the carbon cycle in the past. This sink constitutes a minor component of the carbon isotope mass balance under the modern, high levels of atmospheric oxygen but was much larger in times of low atmospheric O2 or widespread marine anoxia. Waxing and waning of a global

development, deep ocean circulation and global carbon cycling
, 1993
"... The middle Miocene represents a major change in state in Cenozoic climatic evolution, following the climax of Neogene warmth in the late early Miocene at ~ 16 Ma. The early stage of this climatic transition from ~ 16 to 14.8 Ma was marked by major short term variations in global climates, East Antar ..."

THE ROLE OF OCEAN CARBON TRANSPORT IN THE GLOBAL CARBON CYCLE
"... The presentation is intended as an introduction to the workshop on carbon transports. It reviews the major concepts, issues and justifications underlying attempts to estimate ocean carbon transport and reviews the observational approaches to carbon transport estimation. There are several “big issues ..."
