Huge Ancient Methane Seeps Discovered
in the Canadian High Arctic
..........................................................................................................................................................................
Seep mounds are carbonate deposits, often hosting unique fauna, which form at sites of methane leakage into the seafloor. Over 130 were found covering over 10,000 square kilometers of the Cretaceous sea floor. They occurred over a very short time interval immediately following onset of Cretaceous global warming, suggesting that the warming destabilized gas hydrates and released a large burb of methane. Given that methane has 20 times the impact of CO2 as a greenhouse gas, such a release could have accelerated global warming at that time. This discovery supports concerns of potential destabilization of modern methane hydrates.

I've read stories that dragons are hatching under these methane pockets. This day and age nothing would surprise me as being true! 😆
