Methane hydrates are ice like structures forming a solid similar to ice. Significant amounts have been located under sediments on the ocean floors of the Earth. Generally, methane hydrates are more stable in fresh water than in salt water. A region allowing the formation for methane hydrates (largely dependent on depth and pressure) is called…
Measurements at Mauna Loa by the Scripps Institution of Oceanography recorded 415.50ppm carbon dioxide CO2 concentration in the atmosphere for the first time in millions of years. This includes humans who evolved with around 280ppm. Temperature follows CO2, thus as additional carbon pollution is heating the atmosphere, with about 90% of this extra energy accumulated…

Abstract The global warming potential of methane (CH4) is about 30 times stronger than that of carbon dioxide (CO2) over a century timescale. Methane emission is hypothesized…

This week, #NASAExplorers head back in time…by going underground. In the Arctic, a frozen layer of soil – permafrost – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane. Release via https://www.youtube.com/watch?v=y7ZbghndiwQ
