Winter Triticale: A Long-Term Cropping Systems Experiment in a Dry Mediterranean Climate Open
Triticale (X Triticosecale Wittmack) is a cereal feed grain grown annually worldwide on 4.2 million ha. Washington is the leading state for rainfed (i.e., non-irrigated) triticale production in the USA. A 9-year dryland cropping systems pr…

The ultimate cost of carbon Open
We estimate the potential ultimate cost of fossil-fuel carbon to a long-lived human population over a one million–year time scale. We assume that this hypothetical population is technologically stationary and agriculturally based, and esti…

an interesting curiosity Open
This is an interesting, thorough characterization of the distribution of methane trapped within CaCO3 in glacial fore field deposits.The methane is released when the CaCO3 is dissolved in acid, a somewhat aggressive analog for chemical wea…

Carbon Open
This chapter elucidates the importance of carbon to the Earth system and outlines the global debate on its use and impact. The element manifests itself through a number of reservoirs: the crust and mantle (the overwhelming majority), disso…

A model of mercury cycling and isotopic fractionation in the ocean Open
Mercury speciation and isotopic fractionation processes have been incorporated into the HAMOCC offline ocean tracer advection code. The model is fast enough to allow a wide exploration of the sensitivity of the Hg cycle in the oceans, and …

This is a thorough and polished description of the extension of an existing earth system climate model to deal with the impacts of massive methane releases on climate, ocean chemistry, and the carbon cycle.I don't think it's certain that m…

Near miss: the importance of the natural atmospheric CO2 concentration to human historical evolution Open
When fossil fuel energy was discovered, the timing and intensity of the resulting climate impacts depended on what the natural CO2 concentration in the atmosphere was at that time. The natural CO2 concentration is thought to be controlled …

A stochastic, Lagrangian model of sinking biogenic aggregates in the ocean (SLAMS 1.0): model formulation, validation and sensitivity Open
We present a new mechanistic model, stochastic, Lagrangian aggregate model of sinking particles (SLAMS) for the biological pump in the ocean, which tracks the evolution of individual particles as they aggregate, disaggregate, sink, and are…

A model of the methane cycle, permafrost, and hydrology of the Siberian continental margin Open
A two-dimensional model of a sediment column, with Darcy fluid flow, biological and thermal methane production, and permafrost and methane hydrate formation, is subjected to glacial–interglacial cycles in sea level, alternately exposing th…
