Australia is in the grips of a massive wildfire disaster, intensified by record heat and drought. The military has been called in to evacuate thousands from their homes, and thick plumes of smoke have reached as far as New Zealand, more than 1,000 miles away. While bush fires are an annual occurrence in Australia and deadlier fires have occurred there, this fire season began unusually early and is projected to last for months. Australia just had its hottest and driest year on record, and December was one of the top two hottest months in the country’s history.
