Yes, but at the same time, the fossil record proves that there have been episodes of higher temperature in the last few million years, which have not released gigatons of methane from the permafrost or the sea clathrates. So climate scientist do not know where we stand here, the truth is we have no clear understanding of how methane gets locked up in the first place, and what exactly is needed to unlock it.
