  Methane Blow-Holes Sign of Runaway Climate Change?  


Donna Lisenby | August 2, 2014 8:51 am

Scientists think this mysterious crater may be a giant methane blow-hole that signals the beginning of runaway climate change.

They are calling the point when frozen arctic methane in Canada, Alaska and Russia starts erupting into the atmosphere dragon burps.

Dragon’s mouth … a crater recently discovered in the Yamal Peninsula, in Yamalo-Nenets Autonomous Okrug, Russia. Russian scientists said that they believe the 60-meter wide crater could be the result of changing temperatures in the region.

Check out this story * that contains graphs showing such elevated methane levels that they labeled them WTF.

Rising trend … the “dragon’s breath” methane spikes have been recorded eight times in the past 22 years.
If you have ever wondered whether you might see the end of the world as we know it in your life time, you probably should NOT read this story nor study the graphs or look at the pictures of methane blow holes aka dragon burps.
I think Dr. Jason Box (see "Is the climate dragon awakening?" below), who has highlighted the appearance of dangerous spikes in methane above Siberia, sums it up best, “If we don’t get atmospheric carbon down and cool the Arctic, the climate physics and recent observations tell me we will probably trigger the release of these vast carbon stores, dooming our kids’ to a hothouse Earth.”

* Are Siberia’s methane blow-holes the first warning sign of unstoppable climate change?

WHAT do three enormous craters in the Siberian wastelands have to do with a terrified American climate scientist? Methane. And that’s something to scare us all.

The end of the world could be starting right now — in a frozen Siberian wasteland known as Yamal. It translates as “The End of the Land”.

The first mysterious crater was spotted by oil workers earlier this month. It was an 80m wide cavern that reached deep into the earth.

Since then, the Siberian Times reports goatherds have found a further two enormous vents in the ground.

Russian researchers have returned from their investigation of the first find and taken water and soil samples to help resolve how the hole was formed.

Some say aliens. Some say they’re “hellmouths” — gateways to the undead.

But scientists already have a pretty good idea.
Explosive vents of vast quantities of methane gas.

Now a new, ominous, name could be attached to them: Dragon’s mouths.

Here’s where a blog posted by American professor in glaciology Dr Jason Box   
at the weekend comes in: “The dragon breath hypothesis has me losing sleep.”**


** Is the climate dragon awakening?

Using a vast and credible set of climate measurements and physics, James Hansen’s Storms of My Grandchildren makes the case that humans overloading the atmosphere with carbon would eventually trigger the release of vast additional carbon stores locked in shallow sea gas hydrates and from Arctic tundra.

In my professional opinion as a climatologist with more than 70 externally reviewed scientific publications, after 12 years of university education focused on atmospheric and oceanic science, and followed by 10 years of university lecturing on micro and mesoscale meteorology theory and instrumentation, Hansen’s warnings should be met with an aggressive atmospheric decarbonization program.

We have been too long on a trajectory pointed at an unmanageable climate calamity; runaway climate heating.
 If we don’t get atmospheric carbon down and cool the Arctic, the climate physics and recent observations tell me we will probably trigger the release of these vast carbon stores, dooming our kids’ to a hothouse Earth. [ That’s a tough statement to read when your worry budget is already full as most of ours is.

Another SNIPPET (full story at link I just gave you):

My understanding was that the methane bubbles can’t or don’t make it to the surface, instead are converted to much less potent carbon dioxide before reaching the surface. Then, here’s what we hear from 4 days ago   :ofrom a Swedish team now surveying the Laptev sea with a very high-end icebreaker, named for the main Norse god.

The Swedish team states “At several places, the methane “bubbles“ even rose to the ocean surface. That’s damn scary.    Atmospheric methane release is a much bigger problem than atmospheric carbon dioxide release, since methane is ~20 times more powerful greenhouse gas. If as it seems, sea ice reduction is destabilizing the shallow Arctic Ocean continental shelf waters. Without the reflective cover, the ocean is taking on a lot more solar heating during the 24 h summer days, making it harder for the sea ice to reform, in a self compounding feedback process. Places like the Laptev and East Siberian seas, are shallow, and the water column can more easily be mixed by wind action than when sea ice cover was there. This new heating and mixing can be what unlocks the shallow sea gas hydrates, allowing the methane up to the surface.

The methane bubbles they filmed boiling up toward, even to the surface of the Arctic Ocean.
