Climate Change Could Shrink Australia's Killer Waves

Totally bogus, man. Climate change could quell the biggest waves on Australia's east coast, a new study suggests.

Australia's monster swells are typically caused by storms in the Pacific known in Australia as east coast lows, which are driven by air pressure differentials. By the end of the century, climate change will change those pressure differentials such that Aussies can expect to see a third fewer killer waves, according to a study that published Mar. 9 in the journal Nature Climate Change.

Fewer big waves could also change the shape of beaches, as waves determine how much sand the ocean carries onto, and off of, the beach, Mark Hemer from CSIRO, Australia's national research organization in Hobart, told New Scientist.
