I know about the "flipped s-curve" that is methane emissions (inflection point in 2007) is it really considered a tipping point though? Do you have some good papers on that?

Here's a paper from July https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GB007875 https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GB00... 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 Overall, there is a growing research output although much is still unknown. See for example: https://www.nature.com/articles/d41586-023-00616-x https://www.nature.com/articles/d41586-023-00616-x https://www.nature.com/articles/s41558-023-01629-0#Sec1 https://www.nature.com/articles/s41558-023-01629-0#Sec1 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2018GB006009 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/201... > Rising methane could be a sign that Earth’s climate is part-way through a ‘termination-level transition’ https://theconversation.com/rising-methane-could-be-a-sign-that-earths-climate-is-part-way-through-a-termination-level-transition-211211 https://theconversation.com/rising-methane-could-be-a-sign-t... >‘Exceptional’ surge in methane emissions from wetlands worries scientists https://www.carbonbrief.org/exceptional-surge-in-methane-emissions-from-wetlands-worries-scientists/ https://www.carbonbrief.org/exceptional-surge-in-methane-emi...

  Thank you so much, I think I might have seen the first paper, will plow through the rest later, it will take me some time!
