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 ...
Direct evidence was obtained in 1995 when data from the Hubble Space Telescope and other observations suggested the existence of liquid methane on Titan, either in disconnected pockets or on the scale of satellite-wide oceans, similar to water on Earth. [5] The Cassini mission affirmed the former hypothesis, although not immediately.
Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
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 ...
The free gas zone is a zone of freed methane in a hydrate formation, beneath the hydrate stability zone. It can influence the rate of methane output at a ridge or ridge region. A large free gas zone makes more methane available to be released into the open ocean, and, thus, can likely be more influential on climate change than a smaller one. [11]

On Dec. 5, a video shows Weil jumping in the lake to rescue his two dogs. “Sonic walked off first fell in and Yobo followed him, fell in,” Weil told the news outlet.
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.
