Scientists blow up decades of thinking on why hurricanes are becoming more deadly

When analyzing and tracking hurricanes and storms that develop in the North Atlantic Ocean, meteorologists and scientists have long looked toward the Atlantic Multidecadal Oscillation (AMO) for justification.

Understood as a naturally occurring phenomenon, the AMO is supposed to cycle through warm and cool phases every 20-40 years, which accounts for seasonal hurricane activity.

New research posits that there is no AMO at all, however, and that changes in hurricane activity within the Atlantic are directly related to human-caused climate change.

Published in the journal Science, a team of researchers argue that the AMO is not an entity in and of itself; rather, it is a manifestation of the effects of anthropogenic greenhouse gas emissions, or fossil fuels emitted into the atmosphere from human activity.

In short, the AMO is not responsible for varying hurricane activity - humans are.
