WEBDec 15, 2021 · Pitted cones are invaluable windows into the subsurface and intriguing astrobiology targets for Martian life considering that they potentially formed from diapiric upwelling of fine-grained sediments (i.e. mud volcanism), a process that on Earth is often associated with methane release.
A 485-million-year history of Earth’s surface temperature - Science
WEBPhanDA indicates that Earth’s temperature has varied between 11° and 36°C over the past 485 million years. This range is larger than previous reconstructions; however, PhanDA agrees well with independent GMST estimates from the Cenozoic, providing confidence in its larger dynamical range.
