← ScienceWhich consequence occurs when methane hydrate dissociates rapidly?
A)Large methane release accelerates warming✓
B)Hydrate reforms under previous conditions
C)Ocean salinity decreases near deposits
D)Increased oxygen solubility buffers climate
💡 Explanation
Methane hydrate dissociation releases large amounts of methane (a potent greenhouse gas) through a positive feedback loop. The clathrate breakdown increases atmospheric methane, because this promotes further gas release through thermal runaway, rather than causing mere local salinity changes.
