Methane and microbes
Article Abstract:
Methane is not only a fossil fuel but also a key player in the carbon cycle and is a powerful greenhouse gas whose concentration in the atmosphere has increased continuously over the past hundred years. The microorganisms involved couple the oxidation of methane to denitrification in the absence of oxygen, which from a mechanistic viewpoint is a challenging reaction.

Release of methane from a volcanic basin as a mechanism for initial Eocene global warming
Article Abstract:
An evidence for the presence of thousands of hydrothermal vent complexes identified on seismic reflection profiles is presented. The main cause of excessive warming during the initial Eocene thermal maximum (IETM) is the explosive release of metamorphic thermogenic methane during the intrusive phase of North Atlantic Volcanic Province (NAVP).

Warming the world
Article Abstract:
Jean-Baptiste Joseph Fourier is credited with the discovery of the greenhouse effect, whereby the presence of an atmosphere acts to increase a planet's surface temperature. Fourier's framework of energy balance establishes that a planet obtains energy at a certain rate from various sources, and warms up until it loses heat at the same rate.
