Is Australia the Face of Climate Change to Come?

Extreme weather Down Under may foreshadow events on a global scale.

In early 2012 once-in-a-century floods submerged swaths of Great Britain and Ireland, causing some $1.52 billion in damages. Then in June record-high temperatures in Russia sparked wildfires that consumed 74 million acres of pristine Siberian taiga. Months after that, Hurricane Sandy pummeled seven countries, killing hundreds and running up an estimated $75 billion in damages. Just this week, a tornado of virtually unheard of size and ferocity tore through a small city in Oklahoma, leaving 24 people dead.

Each of these one-off traumas was bad enough, wreaking havoc, but in Australia such events seem to be becoming commonplace.

The Lucky Country has experienced a major spike in extreme weather in the past few years, with a string of devastating incidents just since January.

That has people wondering if the island continent is somehow a perfect bellwether for the Earth's changing climate. So scientists are bearing down on the problem with intensity, investigating Australia's increasingly violent weather patterns and trying to figure out what they might portend for the rest of the world as our climate changes.

So Hot Even the Summer Got Angry

The rough-hewn sandstone buildings perched atop Observatory Hill have been keeping an eye on Sydney Harbor since 1858. They've pretty much seen it all—from the installation of the city's first gaslights to the construction of the now iconic Sydney Opera House and Harbor Bridge.

But at 2:55 p.m. on January 18, 2013, meteorological equipment in the observatory registered something new: a read-out marking the hottest day in the city's history: 45.8°C (114.4°F).

Much of the continent was languishing in the grip of a heat wave that would break 123 heat and flood-related records in 90 days—among them, the hottest summer on record and the hottest seven consecutive days ever recorded.

At the time these statistical dramas, and their possible significance, paled against the imperative of not self-combusting on your walk from office to car.

At the Pink Roadhouse in the outback town of Oodnadatta—whose locals are legendary for the stoicism with which they have long dealt with living in Australia's hottest town—temperatures pushed so high that gasoline vaporized before it even made it into the fuel tank.
