Methane hydrates are extremely difficult to study, and could either be an important energy source or a source of methane, a greenhouse gas that is 20 times more potent than CO2.

The methane—normally frozen at great pressure as gas hydrates embedded within subterranean rock—can become dislodged and transform into gaseous bubbles expanding geometrically as they explode ...

Methane hydrates occur in five geographic settings (or sectors) that must be individually evaluated to determine their susceptibility to warming climate (Figure 1). The percentages assigned to ...
