Arctic Methane Seeps Slow Global Warming, Reverse Ocean Acidification and Cure Hypoxia
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…
The Arctic Methane Scare: Oversold
By PAUL C. “CHIP” KNAPPENBERGER and PATRICK J. MICHAELS Methane is all the rage. Why? Because 1) it is a powerful greenhouse gas, that molecule for molecule, is some 25…
Claim: Arctic sea ice plays a pivotal role in the Arctic methane cycle
Nature study on greenhouse gas feedback mechanisms between the atmosphere, sea ice and ocean From the ALFRED WEGENER INSTITUTE, HELMHOLTZ CENTRE FOR POLAR AND MARINE RESEARCH The ice-covered Arctic Ocean…
The 'Arctic Methane Emergency' appears canceled due to methane eating bacteria
Many readers know that we’ve covered the supposed “ticking time bomb” of methane that is supposedly going to be released somewhere, somehow, either from methane clathrates on the sea floor…
Defusing the Arctic Methane Time Bomb
Guest Post by David Middleton The Arctic methane time bomb keeps ticking… From Scientific American… Climatewire More Arctic Methane Bubbles into Atmosphere A new study suggests more than twice as…
Gavin on why the Arctic methane alarm is implausible
Guest Essay by Dr. Gavin Schmidt, NASA GISS Yesterday, I carried this story: An alarmist prediction so bad, even Gavin Schmidt thinks it is implausible Today, on Twitter, Karel Haverkorn…
Arctic methane emergency called off?
Here’s the issue, as described in Wikipedia: The Arctic region is one of the many natural sources of the greenhouse gas methane. Global warming accelerates its release, due to both…
The moon controls the release of methane in Arctic Ocean
It may not be very well known, but the Arctic Ocean leaks enormous amounts of the potent greenhouse gas methane. These leaks have been ongoing for thousands of years but…
Study: Arctic ocean ‘methane bomb’ really isn’t anything to worry about
From the UNIVERSITY OF ROCHESTER comes this study that backs up a study that we reported on just a few days ago about methane clathrates on the ocean floor. The so-called…
Huge Ancient Methane Seeps Discovered in the Canadian High Arctic
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…
Inconvenient: Studies find methane and carbon dioxide release is highest in the Arctic during the region’s cold season
From San Diego State University and the “say anything to support the cause” department, comes this press release written by a fellow who obviously does not understand what it means…
Surprise finding: Arctic Ocean methane does not reach the atmosphere
From the CAGE – CENTER FOR ARCTIC GAS HYDRATE, CLIMATE AND ENVIRONMENT and the cancel the “methane time bomb” department comes this surprising finding: 250 methane flares release the climate gas…
Abiotic methane discovered under the Arctic Ocean
From CAGE – Center for Arctic Gas Hydrate, Climate and Environment New source of methane discovered in the Arctic Ocean Methane, a highly effective greenhouse gas, is usually produced by…
Inconvenient study: Methane seepage from the Arctic seabed has been occurring for millions of years
Despite the ever present wailing from green activists that we are sitting on a “methane catastrophe”, it’s simply business as usual for Earth in the Arctic. Even Dr. Gavin Schmidt…
Methane estimates from the Arctic double, but there's no cause for alarm
From the University of Alaska, Fairbanks Study: Arctic seafloor methane releases double previous estimates The seafloor off the coast of Northern Siberia is releasing more than twice the amount of…
Remember the panic over methane seeping out of the Arctic seabed in 2009? Never mind.
Remember this BBC story? Turns out it is another one for the Climate FAIL file. All sorts of wailing came from that by climate alarmists. The New Scientist claimed there…
Might Arctic Warming Lead to Catastrophic Methane Releases?
Guest post by Indur M. Goklany In the earlier post reporting on the recent greening of the Arctic, some commentators — Crispin in Waterloo, BillD, Jimbo — have alluded to…
Monitoring Arctic Permafrost with Satellites, Supercomputers, and Deep Learning
“The ice wedges form from the freezing and melting of soil in the tundra,” said Liljedahl. “Some of them are tens of thousands of years old.”
Arctic Ocean Started Getting Warmer Decades Earlier Than We Thought – Study
“Climate simulations generally do not reproduce this kind of warming in the Arctic Ocean, meaning there’s an incomplete understanding of the mechanisms driving Atlantification,” said Tommaso. “We rely on these…
Natural feedback or human activities? A new study points to agricultural and industrial sources as the main cause to the soaring atmospheric methane
“Good news is the natural feedback is still not that strong. But without substantial mitigation actions, we will lose the opportunity to control methane as we will have no solution…
NASA at Your Table: Where Food Meets Methane
In addition to the human sources, methane is also produced in natural settings. The greatest natural source of methane is wetlands, which contribute 30% of global methane emissions. Other natural sources…
Holocene Antarctic CO2 Variability or Lack Of
Guest Post by Renee Hannon Introduction This post examines CO2 ice core measurements from Antarctica during the Holocene Epoch. The key CO2 dataset for paleoclimate studies is the EPICA Dome…
Study suggests great earthquakes as cause of Arctic warming
MOSCOW INSTITUTE OF PHYSICS AND TECHNOLOGY Research News A researcher from MIPT has proposed a new explanation for the Arctic’s rapid warming. In his recent paper in Geosciences, he suggests that…
