Macro-Engineering Lake Eyre with Imported Seawater

By conduction and thermal radiation (~11.7%) and rising air (~7%), approximately 18.7% of the Earth’s energy budget is used for direct heating of the air. Whatever the causes—perhaps, in part, an expansion of the width of the Earth’s Southern Hemisphere atmospheric Hadley cell (Johanson and Fu 2009; Liu et al. 2007a, b)—a widening of the Tropical Zone air circulation and a southward shift of the Southern Hemisphere’s tropospheric jet stream and Australia’s associated subtropical arid lands appears to be taking place (Fu et al. 2006; Evans et al. 2009). It is worth noting, too, that since the “Geocentric Datum of Australia 1994” became Australia’s newest country-wide geographical coordinate system, it has been discovered and documented subsequently that Australia, an isolated landmass, is moving to the Northeast at ~3 cm/year. The geographical shift of the continent’s supporting tectonic plate bodes a future change in Australia’s vital hydrologic cycle. Australia is the world’s driest permanently inhabited continent and it has the most variable precipitation, with periods of widespread drought (Sohn 2007).
