As you know, methane and CO2 are greenhouse gasses that increase the temperature of the ocean. This is where the most important threat is going to come from.
Scientists have been trying to figure out for years what caused the Permian Mass Extinction 251 million years ago. This was the big one. They have probably pinned it down now. When the ocean heats up it quits giving off oxygen and gives off hydrogen sulfide, "sewer gas" instead. The animals probably died of suffocation, direct results, (lungs dissolved from battery acid) and/or long term stress. This has dire implications for our future because it could happen again. People don't seem to care about the temperature going up but I think it will hit home when they find out that death from sewer gas may result.
We are in an emergency situation right now . How are we going to lower the temperature of the Arctic 9 degrees Fahrenheit and how are we going to prevent the temperature of the ocean from going up or try to lower it after it has gone up?
Does anyone know what the temperature of the ocean would have to be to start giving off hydrogen sulfide?
I don't want to wait for the atmosphere to turn green to find out.
