Game Over or Overtime?

As we reported two years ago, an international group of scientists, the Arctic Methane Emergency Group has been sailing into the Arctic waters around Norway and Russia to take samples of methane bubbling from ocean clathrates — frozen methane deposits on the sea floor. Some of their findings, very preliminary, are now making their way into the blogosphere, but like many, we await peer-review published articles or discussion in the next IPCC report — AR5 — due in 2014, before we draw hard conclusions.

The preliminary reports, if they can be believed, are frightening.

One report last February was titled, “Global Extinction within one Human Lifetime as a Result of a Spreading Atmospheric Arctic Methane Heat wave and Surface Firestorm.” Its author, Malcolm Light, predicted, “This process of methane release will accelerate exponentially, release huge quantities of methane into the atmosphere and lead to the demise of all life on earth before the middle of this century.”

Light wrote:

“The warning about extinction is stark. It is remarkable that global scientists had not anticipated a giant buildup of methane in the atmosphere when it had been so clearly predicted 10 to 20 years ago and has been shown to be critically linked to extinction events in the geological record (Kennett et al. 2003). Furthermore all the experiments should have already been done to determine which geoengineering methods were the most effective in oxidising/destroying the methane in the atmosphere in case it should ever build up to a concentration where it posed a threat to humanity. Those methods need to be applied immediately if there is any faint hope of  reducing the catastrophic heating effects of the fast building atmospheric methane concentration.”

Light’s proposed geoengineering solution is to piggyback on the Air Force’s HAARP high energy communications network to broadcast a 13.56 MHZ pulse to transform methane in the stratosphere and troposphere to nanodiamonds and hydrogen. Other geoengineering proposals include genetically engineered methanotrophic bacteria that eat methane in soil and air and iron-based catalysts that can oxidize high concentrations of methane in ocean water and raindrops.

All of this seems a bit frantic and desperate, enough to push the skeptical scientist in us to ask, “Are we really there yet?”

Some arctic sea regions as large as one kilometer in diameter are indeed “frothing” from massive gas releases from previously frozen CH4 deposits. Beginning in 2010, Igor Semiletov of the Russian Academy of Sciences said his research team discovered more than 100 plumes, and estimates there are “thousands” over a wider area, extending from Russian mainland to East Siberian Arctic Shelf. 

“Earlier we found torch-like structures, but only tens of meters in diameter. This is the first time we found continuous, powerful, impressive seeps more than 1,000 meters in diameter. It’s amazing.  We carried out checks at 115 stationary points and discovered methane of a fantastic scale—on a scale not seen before,” Semiletov said.
