RE: Joe Romm has written that what is happening there is a foretaste of what is to come in other parts of the world over the next 50-100 years Joe Romm sounds like a serious wacko. Queensland has a long history of serious flooding and droughts. --------------------------------------------------------------- bom.gov.au en.wikipedia.org Causes of flooding In northern Australia, most of the big floods occur in summer or early autumn in association with tropical cyclones or intense monsoonal depressions. These systems can produce staggering quantities of rainfall - as much as 1,000 millimetres in a few days. Outside the tropics, coastal areas of eastern Australia mostly receive their flood rains from so-called "east coast lows" that develop over the Tasman Sea. In the southern states, flooding is mostly a winter-spring phenomenon, associated with unusually frequent low pressure systems and fronts. However some major events have occurred in the summer half-year as systems of tropical origin extend or move south. Some inland floods, notably those of Lake Eyre, may be initiated by rain falling many hundreds of kilometres away. Flooding and La Niña/El Niño Flooding, unlike drought, is often quite localized, and therefore not as closely tied to broad-scale controls like the El Niño-Southern Oscillation phenomenon.<span style='font-size:20px;color:blue' However the La Niña years of 1916, 1917, 1950, 1954 through 1956, and 1973 through 1975, were accompanied by some of the worst and most widespread flooding this century. It can safely be said that, over much of Australia, flooding is more likely than usual during La Niña years, and less likely in El Niño years.</span> bom.gov.au
