When it comes to the connection between anthropogenic (human-caused) climate change and extreme weather, the gap gets smaller each year. There are clear links to drastic changes in hurricanes, floods, droughts, heat waves, fires, and winter extremes. What about severe weather? We don't hear much about bigger and more dangerous tornadoes... that's because the connection between a warming world and severe weather like thunderstorms and tornadoes is much wider than with the others. To dig into the details on this and find out what scientists do know relating to climate change and severe weather, I spoke with a leading expert in such research.Â
