The carbon cycle is a natural biogeochemical cycle in which carbon as CO2 is transferred from the atmosphere to the land and ocean, where it resides in another form before returning to the atmosphere as CO2. The principal processes involved in transfer from the atmosphere are the dissolution of...

A growing body of evidence suggests that animals can underpin the carbon cycle and therefore NCS9,10,11. In particular, animals can be determinants of carbon recovery in tropical restoration projects, given that they are essential for seed dispersal12,13. Seed arrival at degraded sites is a key...
Conceptual diagram of ice sheets in the global carbon cycle. The diagram indicates the potential direct and indirect impacts of ice sheets. (1) direct sequestration or emission of CO2/CH4 by microbial activity in ice sheets, (2) burial of terrestrial OM exported from ice sheets by rivers, (...
In 2014, the Fifth Assessment cycle of the IPCC will be completed following the release of the reports of Working Groups II (impacts, adaptation and vulnerability) and Working Groups III (mitigation of climate change), and finally the Synthesis Report, the combined synthesis product based on all...
This electrode material has a long lifetime, good power density and good cycle life. Liu et al. produced carbon aerogel based on resorcinol–formaldehyde and activated by CO2 [59]. This aerogel had a surface area of 3432 m2/g and yields a capacitance of 152 F/g. This electrode material ...

Schematic diagram of AHD model geometry and its settings: (a) fluid discharges from a pipe through an inlet of radius r0 (red point) with total flow rate Q and temperature Tin. The flow is distributed radially, where it cools by transferring heat to the rock below and above (color-gradien...
Carbonate precipitation is a major process in the global carbon cycle. It was recently proposed that authigenic carbonate (carbonate precipitated in situ at the sediment–water interface and/or within the sediment) played a major role in the carbon cycle throughout Earth’s history. The carbon iso...
