Mass Extinction Time Bomb: Methane

Experts say methane emissions from the Arctic have risen by almost one-third in just five years, and that sharply rising temperatures are to blame.What very few people understand are both the short and long range consequences for the planet in regards to a sudden increase in Methane emissions.
As the Guardian points out:

This recent discovery follows a string of reports from the region in recent years that previously frozen boggy soils are melting and releasing methane in greater quantities. Such Arctic soils currently lock away billions of tons of methane, a far more potent greenhouse gas than carbon dioxide,leading some scientists to describe melting permafrost as a ticking time bomb that could overwhelm efforts to tackle climate change.

Lack of action in international climate change talks risks extreme weather events such as the typhoon that devastated the Philippines three weeks ago being repeated, as Paddy Ashdown has warned. The former Liberal Democrat leader said that the lack of energy at the UN climate talks, which wrapped up in Warsaw last weekend, left him”speechless.”Writing in the Guardian, Ashdown also said that climate change is contributing to extreme weather events, that the role of human-caused emissions in global warming is having fatal consequences and that Typhoon Haiyan is a preview of what the future holds.
Now let’s move to the United States where a late November story by Seth Borenstein (Huffington Post) reveals:

The United States is spewing 50 percent more methane- a potent heat-trapping gas- than the federal government estimates, a new comprehensive scientific study says. Much of it is coming from just three states: Texas, Oklahoma and Kansas. . . The study estimates that in 2008, the U.S. poured 49 million tons of methane into the air.That means U.S. methane emissions trapped about as much heat as all the carbon dioxide pollution coming from cars, trucks, and planes in the country in six months.

Now that I’ve confirmed the rapid Methane buildup both in the rapidly melting Arctic permafrost as well as domestically, let’s throw a historical fact into the equation to truly define the current ticking Methane mass extinction time bomb.
The Permian-Triassic (P-Tr) extinction event, informally known as the Great Dying, was an extinction event that occurred 252 million years ago, forming the boundary between the Permian and Triassic geologic periods, as well as the Paleozoic and Mesozoic eras.It was the Earth’s most severe known extinction event, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. It is the only known mass extinction of insects. Some 57% of all families and 83% of all genera became extinct. Because so much biodiversity was lost, the recovery of life on Earth took significantly longer than after any other extinction event, possibly up to 10 million years.This event has been described as the “mother of all mass extinctions.”
The Plant eating Dicynodon was one of few survivors of Permian Mass extinction 250 million years ago when 95% of all life died.
I implore you to watch the BBC Documentary video The Day the Earth Died,which brilliantly describes the search by geologists throughout the world to discover the cause of this mass extinction event millions of years ago. At first they thought it was a giant asteroid, similar to the event that wiped out the dinosaurs 65 million years ago due to the after-effects of an asteroid impact off the Yucatan Peninsula. Their search for the Permian killer took several twist and turns until the late 1900’s when they discovered the evidence of a buildup in Methane Hydrate with massive quantities of carbon 12 in Permian crust deposits. They then postulated that global warming led to a 5 degree increase in global temperature which led to a massive release of carbon 12 from the Methane Hydrate which led to a 10 degree increase in Global temperature which then literally wiped out life on Earth. It is a must see 48 minute BBC video.
So where are we now regarding Global warming?

I agree with Gaius Publius who writes in America Blog that we could see 7 degree C (12 degree F) warming, and a mass extinction, by 2100. Here’s why: No one is taking into account the consequences of rapid Methane build up and resultant carbon 12 increase. No one is considering what will happen if the Methane emissions from the Arctic permafrost continue to accelerate.

The sad realization for an apathetic world and main stream press is that we may already be beyond the point of no return- and many others agree.

We are upsetting the atmosphere upon which all life depends. In the late 80s when I began to take climate change seriously, we referred to global warming as a ‘slow motion catastrophe’ one we expected to kick in perhaps generations later. Instead, the signs of change have accelerated alarmingly. -David Suzuki

  1. Very frightening article. One more indication that working to avert a climate catastrophe and other environmental disasters must become a central organizing principle for society today.
    One generally overlooked approach is a major shift away from the production and consumption of meat and other animal products.
    It may seem naïve to argue that a mere change of diet could be a potent prescription for combating climate change, but the evidence is incontrovertible, and slowly the public is getting the message.
    Much of global warming discussions by governments, environmental groups and individuals over the past 20 years has focused on implementing changes in energy use and given little attention to the impact of our diets. This trend changed somewhat upon publication of a landmark 2006 report by the United Nations Food and Agricultural Organization (FAO), estimating that livestock production globally is responsible for more greenhouse gas emissions (GHGs, in CO2 equivalents) than is emitted from all of the world’s cars, planes, ships, and all other means of transportation combined. The FAO report, Livestock’s Long Shadow, also projected that the world’s current annual consumption of about 60 billion land-based animals will double by mid-century if current human population growth and dietary trends continue. The resulting increase in GHGs would largely negate reduced GHG emissions from conservation and improved efficiencies in transportation, electricity, and other sectors, making it extremely difficult, if not impossible, to reach the GHG reductions that climate experts believe essential to avoid a climate disaster. While that doubling may not occur, it is troubling that in the face of livestock’s strong role in warming the planet, many countries are encouraging the expanded consumption of animal products. 

    More recently, an in-depth analysis, “Livestock and Climate Change,” by World Bank Group environmental specialists Robert Goodland and Jeff Anhang, was published in the November/December 2009 issue of World Watch magazine. The authors argue that there are sources of GHGs from the livestock sector that were overlooked, underrepresented or placed in the wrong sectors in the FAO report, and concluded that the livestock sector is responsible for at least 51 percent of all human-induced GHGs.
    Goodland and Anhang call for the replacement of livestock products with plant-based alternatives, based on the rationale that this would result in quick reductions in atmospheric GHGs, while also reversing on-going world food and water crises. 

    Leading climate specialists have focused increasingly on the role of food in global warming, pointing out that there is no more powerful environmental action that any individual can take than adopting a plant-based diet. Bottom line: it is essential that the consumption of meat and other animal products be reduced to help shift our imperiled planet onto a sustainable path.
