Normally, many bushfires ease overnight, as temperatures fall and moisture in the air rises. But these are not normal times, as Queensland’s early-season fires are showing Calum Cunningham, Postdoctoral Research Fellow, University of Tasmania David Bowman, Professor of Pyrogeography and Fire Science, University of Tasmania Grant Williamson, Research Fellow in Environmental Science, University of Tasmania Licensed as Creative Commons – attribution, no derivatives.

Storms are the greatest threat to beach erosion, not sea level rise, research reveals. This is the longest continuous beach monitoring survey in the Southern Hemisphere.
