The Arctic Methane Monster's Rapid Rise


Researcher Jennifer Hynes recently gave a frightening presentation about the situation in the Arctic and the odds that things will rapidly spiral out of control soon, escalating into runaway global warming a few decades from now. 




Above, a slide from the presentation, warning about the danger of earthquakes causing methane hydrate destabilization (from: Smoke Blankets North America). As the map below shows, 77 M4+ earthquakes did hit locations around Greenland in the year 2014 up until August 4.


Below is Jennifer's presentation, also on youtube at youtube.com/watch?v=a9PshoYtoxo



The image below shows sea surface temperature anomalies in the Arctic at August 7, 2014.


Warm water is carried into the Arctic Ocean by the Gulf Stream, as illustrated by the image below.

The image shows how the Gulf Stream brings warm water to the edge of the sea ice. Waters close to Svalbard reached temperatures as high as 15.6°C (60.1°F) on August 8, 2014 (green circle). Note that what the image shows are sea surface temperatures only. At greater depths (say 300 m), warm water is pushed through the Greenland Sea by the Gulf Stream. Since the passage west of Svalbard is rather shallow, a lot of this warm water comes to the surface there. The high sea surface temperatures west of Svalbard thus indicate that the Gulf Stream is carrying very warm water (warmer than 15°C) at greater depths and is pushing this underneath the sea ice north of Svalbard.

As said, the situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog at climateplan.blogspot.com and as illustrated by the image below.

AMEG presentation, London June 16, 2012

On June 16, 2012, the Arctic Methane Emergency Group (AMEG) gave a presentation on the situation in the Arctic at the Campaign against Climate Change (CaCC) conference (see video below).

Below an web-copy of the AMEG flyer distributed at the conference:

           


EVERYTHING depends on you helping the Arctic

the Arctic is warming ever faster (1)
the sea ice volume is plummeting (2)
which prefaces a collapse in sea ice extent (3)
Arctic warming already disrupting climate,
  causing unpredictable weather for farmers
 (4)
already escalating emissions of methane (5)
  from vast store in Arctic seabed (6)
and, as methane is a potent greenhouse gas (7)
  risks runaway global warming. (8)

  Demand action to pull back from the brink
Demand that governments assess the threat
from Arctic methane release, and
Demand swift action to COOL THE ARCTIC.
