New DOE study on methane raises more questions than it answers

From: DOE/LAWRENCE BERKELEY NATIONAL LABORATORY First direct observations of methane’s increasing greenhouse effect at the Earth’s surface Scientists have directly measured the increasing greenhouse effect of methane at the Earth’s surface for the first time. A research team from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) tracked a rise in the warming…

Why did gas hydrates melt at the end of the last ice age?

GEOMAR researchers find links between sedimentation and methane seeps on the seafloor off the coast of Norway Large amounts of the greenhouse gas methane are locked up as solid gas hydrates in the continental slopes of ocean margins. Their stability depends on low temperatures and high pressure. However, other factors that influence gas hydrate stability…

So much for the ‘methane bomb’ – study finds methane hydrate dissociation…’not caused by climate change’

From the HELMHOLTZ CENTRE FOR OCEAN RESEARCH KIEL (GEOMAR) and the soon to be defunct “Arctic Methane Emergency Group” comes this good news. Methane hydrate dissociation off Spitsbergen not caused by climate change Study identifies post-glacial processes as main reason Methane hydrates, also known as flammable ice, occur in many regions of the oceans. But…

NASA-led Study Solves a Global Methane Puzzle

From NASA GODDARD: A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions from global fires. The new study resolves what looked like irreconcilable differences in explanations for the increase. Methane emissions have been rising sharply since 2006. Different research…
