The most significant results of recent research are the findings (1) that methane emissions from rice paddies are strongly dependent on the soil temperature, and (2) that the fluxes of methane from the Chinese rice paddies are up to 10 times greater on average compared with fluxes from rice paddies in other parts of the world. In addition to the main findings there are a number of other significant results. These are: (1) the extension of a time series of concentrations of methane (and also of other gases) at Minqin. The data now span sufficiently long times to estimate trends and seasonal variations and to include Minqin in our global flask sampling network. (2) We have completed further work on bio-gas pits. (3) We have also measured methane in Beijing and found relatively low concentrations for an urban area. 8 figs.
