We could be 16 years into a methane-fueled 'termination' event significant enough to end an ice age

Methane emissions from tropical wetlands have been soaring since 2006.

    From article:

    But in late 2006, something “very, very odd” happened, he said. Methane started rising again, but there was no dramatic shift in human activity to blame — and researchers were left scratching their heads. Then, in 2013, Nisbet and his colleagues realized this rise was accelerating. By 2020, methane was increasing at the fastest rate on record, he said.

    From Wikipedia - Fracking in the United States:

    Between 2005 and 2010 the shale-gas industry in the United States grew by 45% a year. As a proportion of the country’s overall gas production, shale gas increased from 4% in 2005 to 24% in 2012.

    We’ve definitely set off methane deposits in the arctic, the ocean, the tropics, etc. But acting like there’s no way of knowing this could have happened or why is just stupid. The global shale oil boom set off by US development of new extraction technologies due to OPEC pressure, the use of which then spread around the globe is definitely a major contributing factor.

    For the majority of the early phase of the fracking boom up to now, methane was vented as they were trying to maximize oil extraction. Pipelines and methane capture equipment were not in place in many locations and have only begun to be due to the rise in LNG prices resulting from Russian supply destabilization. Further, these were known risks at the time that were ignored with a concern only for maximizing oil production and profits.

    This should surprise no one.

    Fracking boom tied to methane spike in Earth’s atmosphere
    The chemical signature of methane released from fracking is found in the atmosphere, pointing to shale gas operations as the culprit.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
