Many ice sheets that sit like caps over rock crevices trap natural seeps of methane; when they melt, the gas can quickly be released into the atmosphere in "burps". Geologists have long suspected that iced-over geological structures might entrap vast stores of ancient methane that seep from coal and gas deposits,...
