Tropical Cyclones' Role in Carbon Cycle May Reverse with Warming
Key Questions
How do tropical cyclones currently affect ocean carbon levels?
Research indicates cyclones cause net CO2 outgassing from the ocean into the atmosphere. This process releases stored carbon during storm activity.
What change in the carbon cycle role of cyclones is projected under warming?
Under high emissions scenarios, their role may reverse by 2035, turning cyclones into net carbon sinks. This shift could accelerate ocean acidification and affect marine ecosystems.
Why does this research matter for climate policy?
It reframes hurricane impacts beyond immediate damage to include long-term effects on the carbon cycle. Findings tie directly to emissions reduction and marine health considerations.
