Australia's wildfire emergency has no end in sight. This is what scientists warned would happen, and now it is: runaway wildfires of unprecedented scale and destruction are raging around Australia. At least 25 people have been killed, and about 3,000 military personnel have mobilized to assist in the evacuation of about 100,000 residents across the country's South East. The toll on the ecosystem remains less clear, but a widely reported estimate puts the number of wildlife killed at 480 million (not including frogs, bats, or insects.) Today, you'll hear from Marc West, the brother of our executive producer James, who managed to evacuate with his family from one of the hardest hit regions just as the crisis mounted. You'll also hear from one of the world's most prominent scientists studying the intersection of climate change and extreme weather, Michael Mann, who happens to be in Australia witnessing this disaster unfold firsthand. Note: since recording parts of this episode, the reported death toll from the bushfire crisis has risen to at least 25. The estimated numbers of homes destroyed and acres burned have also continued to increase.
