From Western Wire by Michael Sandoval July 18, 2017 “Agricultural and wetland emissions” from the planet’s tropical areas, not oil and gas activities in the United States, are more than likely responsible for a post-2007 global increase in methane levels, according to the National Oceanic and Atmospheric Administration’s Climate.gov. But regulating or mitigating those methane…
Guest post by David Middleton From the “Truth is Stranger than Fiction” files: Are methane seeps in the Arctic slowing global warming? By Randall HymanMay. 8, 2017 , 3:00 PM Good news about climate change is especially rare in the Arctic. But now comes news that increases in one greenhouse gas—methane—lead to the dramatic decline…
New study suggests hydroxyl radicals may be behind unexplained recent increase in methane levels from the CALIFORNIA INSTITUTE OF TECHNOLOGY During the early 2000s, environmental scientists studying methane emissions noticed something unexpected: the global concentrations of atmospheric methane (CH4)–which had increased for decades, driven by methane emissions from fossil fuels and agriculture–inexplicably leveled off. The…
From the GEOLOGICAL SOCIETY OF AMERICA Boulder, Colo., USA: Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, Canadian High Arctic, discovered an astounding number of methane seep mounds in Cretaceous age…
From the US GEOLOGICAL SURVEY The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester. Methane hydrate, which is also referred to as…
From the “it’s that Methane and Ozone Emergency again” department, comes this breathless headline, for a kitchen sink press release that even includes the obligatory faux sinking atoll of Tuvalu. I had to laugh at the first line of the PR, that said: Even if there comes a day when the world completely stops emitting greenhouse…
Guest essay by Eric Worrall Governor Jerry “Moonbeam” Brown has just signed a law to require dairy farmers to reduce bovine methane emissions. California targets dairy cows to combat global warming GALT, Calif. – California is taking its fight against global warming to the farm. The nation’s leading agricultural state is now targeting greenhouse gases…
