In order for the clathrate hypothesis to be applicable to PETM, the oceans must show signs of having been warmer slightly before the carbon isotope excursion, because it would take some time for the methane to become mixed into the system and δ 13 C-reduced carbon to be returned to the deep ocean sedimentary record. Up until the 2000s, the ...
Titan's atmosphere is full of methane, which according to calculations should react with ultraviolet radiation from the sun to produce liquid ethane. Over time, the moon should have built up an ethane ocean hundreds of meters (1,500 to 2,500 feet) deep instead of only a handful of polar lakes.
Frozen methane bubbles from thawing permafrost. Large deposits of frozen methane, when thawing, release gas into the environment. [3] In cases of sub-sea permafrost, the methane gas may be dissolved in the seawater before reaching the surface; however, in a number of sites around the world, these methane chimneys release the gas directly into the atmosphere, contributing to global warming.

A research team made a worrisome discovery off the Siberian coast, The Guardian reports. The scientists say they believe they are first to uncover observational evidence that frozen methane ...
They are mostly visible by a depth of 140 meters, except for the Arctic and Antarctic regions, where the shelves are deeper. The mid-ocean ridges start to appear at a depth of 2000 to 3000 meters. By 6000 meters, most of the ocean is drained except for the deep ocean trenches, the deepest of which is the Marianas Trench at a depth of 10,911 meters.
The other is that as the ocean is warmer with global warming, the water that the eye of the storm is picking up is warmer. Warmer water evaporates quicker, bringing more transfer of heat energy ...
There is evidence for increasing methane emissions since 2004 from a Siberian permafrost site into the atmosphere linked to warming. [8] Radiocarbon dating of trace methane in lake bubbles and soil organic carbon concluded that 0.2 to 2.5 Pg of permafrost carbon has been released as methane and carbon dioxide over the last 60 years.
