Deadly wildfires like those that burned through central Chile and killed at least 133 people this month will become more likely in the South American country as climate change makes the world hotter and drier, according to a report released on Thursday. The fires were Chile's deadliest natural disaster since a 2010 earthquake that killed about 500 people. The report from World Weather Attribution, an international group of scientists that studies the effects of climate change on extreme weather events, analyzed that spike in conditions that feed fires - temperature, wind speed and atmospheric moisture - as measured by a metric called the Hot Dry Windy Index (HDWI).
