The terror of devastating infernos. From Australia to America and Europe, "megafires" are threatening life across the world. Reducing homes and belongings to ash, they also leave a death toll. This series, an international co-production with France, will focus on "megafires." The key driver of frequent "megafires" is the increasing pace of climate change. How do we respond to this state of emergency? In the first part of the program, we will explore the mechanism of these "megafires." We will also report Japan, with its many wooden buildings, is no stranger to "megafires." The threat of an earthquake fire could strike its cities at any time. Is there any way to stop "megafires"?
