Australia Burning

Wildfires scorch Australia in this image taken from the International Space Station and released January 8. To make matters worse, on January 7, the country experienced their hottest day on record, with average temperatures hitting 104.59 degrees Fahrenheit (40.33 degrees Celsius).

Forecasts call for even higher temperatures next week—so high in fact that Australia's Bureau of Meteorology had to add a new color to their temperature scale. (See more pictures of Australia's wildfires.)
