But this year, unusually warm sea surface temperatures — the kind of temperatures that will become the new normal as the Earth warms — revved up an unusually strong weather phenomenon known as La Nina, leading to a volume of water far beyond what anyone had projected.

The dams made a difference — flood waters in downtown Brisbane, a city of 2 million, peaked below their record height of 1974. But the waters still managed to wipe out many apartments and suburbs, leading to 25 deaths across the state of Queensland and leaving thousands homeless for what could be months.

Remarkably, even though power went out, many residents managed to use battery-powered laptops, cell phones, and spotty 3G coverage to post images of the muddy brown devastation swirling about them.

Here we present a selection of images from the Flood of 2011. If you’re moved to donate to the flood appeal, do it!
