But the science is settled, right?
The concern has been that as the world gets warmer, some of the clathrates [methane compounds] would escape into the atmosphere and have a dramatic amplifying effect on global warming.
The CSIRO's Dr David Etheridge says the circumstantial evidence was not good.
"There's evidence in the long-term past, millions of years ago, that this may have occurred," he said.
"It is circumstantial evidence only. What we needed to know for the future is whether the warming that we are currently seeing and which will increase in the future will destabilise these clathrates."
"I think this confirms that source of methane, that potential source of methane, is more stable than we previously thought and that gives us some upper bounds to the future releases that we might expect with a warming world."
