Right, I don't disagree with the plain fact that methane concentrations are increasing, both globally, and apparently in Barrow. There is a decades-long trend of increased methane concentrations.

The question is whether there has been a massive eruption of methane that is unprecedented, and could only come from methane hydrates.

Michael Mann says the "eruption" is consistent with past outliers and we shouldn't over-interpret the data. He says there is no evidence the increase is from permafrost, and that it appears likely to be from anthropogenic (i.e., non-tipping point) sources.

I'm not making an argument against climate change science. I'm making an argument against Dr. Peter Carter exaggerating climate science.

That sounds reasonable. Thanks for the sourcing!
