Policy support, economic incentives and the adoption of irrigation technology in China
Summary: The econometric analyses results revealed that policy supports via subsidies and extension services have played an important role inpromoting the adoption of irrigation technology. Strikingly, the present irrigation pricing policy has played significant but contradictory roles in promoting the adoption of different types of irrigation technology. Irrigation pricing showed a positive impact on household-based irrigation technology, and a negative impact on community-based irrigation technology.
The impact of oceanic heat transport on the atmospheric circulation
Summary: A general circulation model with an aquaplanet setup is used to study the impact of changes in the oceanic heat transport on the atmospheric circulation with focus on the global energy cycle and the atmospheric mean meridional circulation. The atmospheric heat transport compensates the imposed oceanic heat transport. A larger oceanic heat transport leads to a reduction of all components of the energy cycle. Both the Hadley and Ferrel cell show a decline for increasing oceanic heat transport.

Decomposing uncertainties in the future terrestrial carbon budget associated with emission scenario, climate projection, and ecosystem simulation using the ISI-MIP result
Summary: Our MS focused on uncertainties terrestrial C cycling under newly developed scenarios with CMIP 5 experiment. This study is first results to figure out the relative uncertainties of projected terrestrial C cycling in multiple projection components. Only using our new model inter-comparison project datasets enables us to evaluate various uncertainty sources in projection periods. The information about relative uncertainties are useful for climate science and the climate change impact evaluation.
