I don't just write about exoplanets and moons; I also write about climate change issues. Planetary science, after all, includes Earth.⠀ ⠀ Sediment cores can tells us so many things about our planet's past and give us hints at what the future may hold. Using cores taken deep beneath the Arctic, scientists analyzed the escape of thermagenic methane from pockets under the seafloor during two previous periods of warming and the consequential melting of Arctic ice. While there are a host of critters that love that increase in methane, it's not good for most life on the surface.⠀ ⠀ Read my full story: buff.ly/3u7z1ox⠀ ⠀ IMAGE: Massive lumps of carbonate litter the seafloor where large quantities of methane are leaking from the sediments and rocks below, marking the spot Dessandier and colleagues targeted to drill deep sediment cores.
