Large, Troubling Methane Pulse Coincides With Arctic Heatwave, Tundra Fires

10. This scepticism may be justified

They appear to be using a counter argument based on paleoclimate (i.e. such a release doesn't show up in the ice cores at these levels of ocean surface exposure).

OTOH, Wadams et al are using models to project the future.

Its possible the modelers are closer to the truth if the *rate* and temp starting point of warming make a significant difference, because the current rate is unprecedented especially from a cool, more methane-laden period like ours. A past warming event at a gradual rate allows the biosphere to head-off methane buildup, storing that carbon as other forms.
