Sustainable2050, 6 months ago to climate New reconstruction of atmospheric CO2 history: The Miocene (~16 Ma) marks the last time that CO2 concentrations were consistently higher (~480 ppm) than now; Greenland was not yet glaciated at that time, and sea level was some 50 m higher than today. https://www.science.org/doi/10.1126/science.adi5177?s=09 #ClimateChange #Paleoclimate #CO2

atthenius, 6 months ago Read this article about #methane #hydrates observed off the coast of Africa moving 40km from deep-cold waters to the continental shelf: https://scitechdaily.com/fire-ice-time-bomb-discovered-climate-changes-deep-ocean-threat/ Relevant because one of the leading theories for what caused the #PETM (jump in #CO2 and #temperatures at 55 Ma) is the #clathrate gun-- frozen methane in the abyssal ocean thawing & causing sudden warming. https://en.wikipedia.org/wiki/Clathrate_gun_hypothesis But it hinges on methane being shallow enough to being vulnerable to melt. Not time to panic, but wow.
