"As much of inland and eastern Australia sweats through its first heatwave of the summer, a new interactive website has been launched to track where the heat is coming from and to map past heatwaves across the country. Extreme heat has killed more Australians than any other natural hazard in the past 200 years. For example, more people died during the 2009 Victorian heatwave than the Black Saturday bushfires. But as scorcher.org.au explains, a heatwave is more than just one hot day.

"A brutal and potentially historic heat wave is in store for the West as parts of Nevada, Arizona and California may get dangerously hot temperatures starting Thursday and lasting through next week. In fact, by the end of the heat wave, we may see a record tied or broken for the hottest temperature ever recorded on Earth."
