Climate Change and the End of Australia
What is likely to vanish – or be transformed beyond recognition – are many of the things we think of when we think of Australia: the barrier reef, the koalas, the sense of the country as a land of almost limitless natural resources. Instead, Australia is likely to become hotter, drier and poorer, fractured by increasing tensions over access to water, food and energy as its major cities are engulfed by the rising seas.
To climate scientists, it's no surprise that Australia would feel the effects of climate change so strongly, in part because it has one of the world's most variable climates. "One effect of increasing greenhouse-gas levels in the atmosphere is to amplify existing climate signals," says Karoly. "Regions that are dry get drier, and regions that are wet get wetter. If you have a place like Australia that is already extreme, those extremes just get more pronounced."
