I've always been skeptical about this, not because I feel it isn't a threat but because I think that is closing the barn door after the cows have gone. Yes, rising temperatures will melt methane hydrates and cause global warming to be worse, but if we take care of the CO2 problem the methane problem will never materialize.
Now, a government scientist is saying the same thing. Ray Boswell, the technology manager for natural gas technologies at DOE’s National Energy Technology Laboratory said,
“CO2′s going to be your big problem. If it causes a methane problem, that’s like someone burning the rubble of your house after a hurricane already hit.”Yes, methane is being released, but it always has been. It is possible the rate of release in increasing. However, the bottom line is still the same - take care of the CO2 problem and the other problems will take care of themselves.
