WebMethane is a more potent “greenhouse gas” than carbon dioxide which has been the subject of numerous studies of its atmospheric increase in concen- tration since the Little Ice Age and potential contribution to global warming. WebA dust explosion, when a dust cloud is ignited within a confined space, generates a pressure increase that develops quickly to reach a maximum pressure, then the pressure slowly releases. The pressure profile will depend on the material generating the explosion.
