Arctic methane hydrates are destabilizing as we speak.
It's mesmerising and I'm absolutely 100% certain it spells doom very shortly. I'm less afraid today than I've been for the last 18 years of studying it because there's not a damned thing anyone can do about it now, so worrying is over for me. I get to chill for a change. Best of luck to anyone who won't accept the inevitable and my heartfelt sympathies to anyone beginning to try today. 🍿🤪👍
I'd suggest trying to make the rest of your life the best of it....

A pretty picture often helps.
Hydrates that are trapped under permafrost on land in the Arctic, along with those submerged under shallow seas just offshore, could be a more imminent threat. In November 2013 a team led by Natalia Shakhova of the University of Alaska Fairbanks estimated that the East Siberian Arctic Shelf is venting 17 million metric tons of methane into the atmosphere every year—twice previous estimates. Shakhova found significant methane bubbles rising from permafrost-covered hydrate deposits in just 50 meters of seawater. During the area's frequent storms, these bubbles appear to get mixed directly with the atmosphere. Until more research is done, no one can tell whether this dynamic is occurring across the Arctic or even whether the methane is coming primarily from the hydrates or the permafrost. It is yet another “black box” in our understanding.

This is happening because that is, that is happening because this is. We're at the end of days. Finally others will know my status.
Read to the bottom. Read the whole paper.
Abstract.
Atmospheric methane's rapid growth from late 2006 is unprecedented in the observational record. Assessment of atmospheric methane data attributes a large fraction of this atmospheric growth to increased natural emissions over the tropics, which appear to be responding to changes in anthropogenic climate forcing. Isotopically lighter measurements of are consistent with the recent atmospheric methane growth being mainly driven by an increase in emissions from microbial sources, particularly wetlands. The global methane budget is currently in disequilibrium and new inputs are as yet poorly quantified. Although microbial emissions from agriculture and waste sources have increased between 2006 and 2022 by perhaps 35 Tg/yr, with wide uncertainty, approximately another 35–45 Tg/yr of the recent net growth in methane emissions may have been driven by natural biogenic processes, especially wetland feedbacks to climate change. A model comparison shows that recent changes may be comparable or greater in scale and speed than methane's growth and isotopic shift during past glacial/interglacial termination events. It remains possible that methane's current growth is within the range of Holocene variability, but it is also possible that methane's recent growth and isotopic shift may indicate a large-scale reorganization of the natural climate and biosphere is under way.
Key Points.
The rapid growth in the atmospheric methane burden that began in late 2006 is very different from methane's past observational record
Recent studies point to strongly increased emissions from wetlands, especially in the tropics
This increase is comparable in scale and speed to glacial/interglacial terminations when the global climate system suddenly reorganized.

Read the papers and understand them before debunking what the science says is already happening and being ignored by many people at the very top of the climate hierarchy kettled into their professorial positions. We all know who I'm referring to. 😏
