I couldn’t access it, but there’s a Dec 2014 article at the link, just below this one, called “Mars belches methane”. So...couldn’t it be methane? And wouldn’t it be prudent to have the EPA investigate and place restrictions on Mars? Cuz we have enough global warming of our own without Mars adding to it! /sarc
“Mars belches methane.” Hope it doesn’t explode.
good catch, wb.
“These are molecular cages of water-ice in which methane gas is trapped. From time to time, these could be destabilised, perhaps by some mechanical or thermal stress, and the methane gas would be released to find its way up through cracks or fissures in the rock to enter the atmosphere,” the University of Michigan professor told BBC News.
