USA Today op-ed ignores evidence to claim climate change had no role in Hurricane Florence

This op-ed in USA Today makes the claim that Hurricane Florence has no appreciable contribution from human-caused climate change.
Scientists who reviewed the article found that it ignores the evidence for trends in tropical cyclone behavior, including slower movement speed and more intense rainfall. Additionally, sea level rise raised the storm surge of the landfalling tropical cyclone above the level it would have reached a century ago. The article cherry-picks data in misleading way to claim that recent storms are no different from past tropical cyclones…

National Geographic accurately covers research pointing to slower-moving hurricanes

“This is an important topic and the article explains the new research findings clearly… Highlighting how this result about slowing storms is consistent across two studies that employ very different methodologies further helps convey to the public how we try to use multiple lines of evidence to understand how our world works and how it may chance in the future.”
