What would happen if clathrate hydrates, which cover much of the ocean bottom began to melt due to a slight increase in water temperature?

The correct answer would be -  potent greenhouse gases, similar to natural gas, would be released into the atmosphere possibly causing more warming of the oceans and a runaway effect

Explanation:

Clathrate hydrates are the compound that is similar to the ice-like structure that is formed by freezing of water in presence of a huge amount of other compounds or gases like CH4 and others. In this process, these gases are trapped or stuck in the lattice of ice.

In low-temperature seafloor and clathrate hydrate are remain unchanged And if the temperature of water increases clathrate hydrates melts and releases methane gas. Microorganisms perform oxidation of these to form CO2 and release of this Carbon dioxide gas in the atmosphere. As it is known that carbon dioxide is a greenhouse gas, it will increase global warming.
