This week’s On The Radio segment looks at a recent study that examines how climate change affects extreme weather events such as floods and droughts.

Transcript: Attributing extreme weather to climate change

Scientists are becoming increasingly confident attributing extreme weather events to human-caused climate change.

This is the Iowa Environmental Focus.

A March study led by The National Academy of Sciences concludes that scientists are more able to determine how climate change affects the intensity and likelihood of some extreme weather events like floods and droughts. Extreme event attribution, a relatively new science according to the study, has made rapid advancements in the last ten years.

After extreme weather events like the record-breaking precipitation Iowans experienced in the winter of 2015, scientists are often asked if these events can be attributed to climate change. While few if any phenomena can be explained by climate change alone, scientists are now better able to determine how much of an effect climate change may have.
