Global Climate Change: Images of Change

Each week the State of Flux features images of different locations on planet Earth, showing change over time periods ranging from centuries to days. Some of these effects are related to climate change, some are not. Some document the effects of urbanization, or the ravage of natural hazards such as fires and floods. All show our planet in a state of flux.

LATEST IMAGE: Bouncing back from Black Sunday

Victoria, Australia. Left: February 16, 2009. Right: January 5, 2011. A series of bushfires in early February 2009, during a record-breaking heat wave and extremely dry conditions, resulted in the largest loss of life from bushfires Australia has ever recorded. Some 400 individual fires were raging on February 7 alone, a day widely referred to as Black Sunday. The 2009 image shows fire scars and smoke; by 2011 regrowth can be seen. The city of Melbourne is visible in the lower left of each image. Click here to download image.
