Anybody else concerned about global temperatures rising a degree and a half since the late 1800s? Heres an anecdote: The Siberian coal traps volcano explosion raised global temperatures 4-5 degrees, warming the ocean and releasing frozen methane from its deep sea rest. This caused an immense amount of Carbon-12 to go into our atmosphere, raising global temperatures another 4-5 degrees. This lead to what is known as The Great Dying, the massive extinction event predating the dinosaurs. Just over a month ago, the Dept. of Geosciences of Mississippi State Universitys Dr. Adam Sharke penned that his team found widespread methane leakage from the sea floor on the northern US Atlantic margin. Yup, the same frozen methane concentrates that brought about the Permian Extinction that killed 95% of all life on Earth, is leaking from the deep sea. Currently oceans contribute an estimated 2-4% of the Earths atmospheric methane budget as a bubble that transports the methane from the bottom of the ocean floor could have lower than 5% of its original methane content by the time it reaches the surface. Essentially, the more methane bubbles that rise to the surface, the higher contribution of methane the oceans give. In order to suppress this problem, global temperatures need to stabilize (and preferably fall a percent). Yes, global temperatures rising due to carbon emissions is much nicer on the life of Earth than a perpetually burning coal reserve ignited by a volcanic explosion, but Id still rather not see the earth rise 7-10˚ in my lifetime.
