@frigate1985 It’s not CO2 it will release but methane. We are currently adding 26 billion metric tons of CO2 to the atmosphere every year. Natural systems dealt with the natural sources of CO2 release, but are not able to absorb the amount human activity is now adding, so CO2 levels in the atmosphere are rapidly increasing, causing global warming.
There are 400 billion tonnes of methane locked in frozen tundra and as much as 2,500 billion tonnes of methane frozen in methane clathrates at the bottom of the cold oceans. Global warming, if unchecked, will release all of that. Methane is 72 times more harmful as a greenhouse gas than is CO2 in its first year in the atmosphere. Over its full atmospheric cycle, it is 20 times more destructive. If we trigger such a release, we will be looking at sea level rises in the order of 350 feet and temperature increase so extreme that most advanced life on Earth will go extinct. That includes Humans!
