Zewail's team used a laser to fire a pulse of photons into a vacuum chamber filled with a heavy form of methane containing two iodine atoms. (sciencemag.org)
Scientists have also raised the possibility that global warming could release methane from very large ancient carbon reservoirs such as permafrost and gas hydrates — ice - like forms of methane in the sediments at the bottom of the ocean — that become less stable as temperatures increase.

Most farm - related emissions come in the form of methane (cattle belching) and nitrous oxide (from fertilizers and the like). (rainforest-alliance.org)
