State Of Extreme Emergency

by Malcolm Light

PRESIDENT OBAMA MUST DECLARE A STATE OF EXTREME NATIONAL EMERGENCY AND CEASE ORCHESTRATING A WAR WITH RUSSIA. HE MUST RECALL HIS ENTIRE ARMY AND NAVY PERSONNEL TO THE UNITED STATES TO BEGIN A MASSIVE CONVERSION OF THE US ENERGY SYSTEM TO SOLAR AND WIND POWER. THIS CONVERSION MUST RESULT IN ALL 600 COAL POWER STATIONS AND NUCLEAR STATIONS BEING COMPLETELY SHUT DOWN IN THE NEXT 5 TO 10 YEARS. ALL SURFACE TRANSPORT BOTH PRIVATE AND PUBLIC MUST BE ENTIRELY ELECTRIFIED AND AIR TRANSPORT CONVERTED TO METHANE OR HYDROGEN FUEL. IF THIS IS NOT DONE, HUMANITY WILL BE FACING TOTAL EXTINCTION IN AN ARCTIC METHANE FIRESTORM BETWEEN 2040 AND 2050.


The US and Canada must cut their global emissions of carbon dioxide by 90% in the next 10 to 15 years, otherwise they will be become an instrument of mass destruction of the Earth and its entire human population. Recovery of the United States economy from the financial crisis has been very unsoundly based by the present Administration on an extremely hazardous "all of the above" energy policy that has allowed continent wide gas fracking, coal and oil sand oil mining and the return of widespread drilling to the Gulf. Coast. This large amount of fossil fuel has to be transported and sold which has caused extensive spills, explosions and confrontations with US citizens over fracking and the Keystone XL pipeline. Gas fracking is in the process of destroying the entire aquifer systems of the United States and causing widespread earthquakes. The oil spills are doing the same to the surface river run off.

We are now facing a devastating final show down with Mother Nature, which is being massively accelerated by the filthy extraction of fossil fuels by US and Canada by gas fracking, coal and tar sand mining and continent wide bitumen transport. The United States and other developed nations made a fatal mistake by refusing to sign the original Kyoto protocols. The United States and Canada must now cease all their fossil fuel extraction and go entirely onto renewable energy in the next 10 to 15 years otherwise they will be guilty of planetary ecocide - genocide by the 2050's.

The volume transport of the Gulf Stream has increased by three times since the 1940's due to the rising atmospheric pressure difference set up between the polluted, greenhouse gas rich air above North America and the marine Atlantic Air. The increasingly heated Gulf Stream with its associated high winds and energy rich weather systems then flows NE to Europe where it recently pummeled Great Britain with catastrophic storms. Other branches of the Gulf Stream then enter the Arctic and disassociate the subsea Arctic methane hydrate seals on subsea and deep high - pressure mantle methane reservoirs below the Eurasian Basin- Laptev Sea transition. This is releasing increasing amounts of methane into the atmosphere producing anomalous temperatures, greater than 20°C above average. Over very short time periods of a few days to a few months the atmospheric methane has a global warming potential from 1000 to 100 times that of carbon dioxide.


There are such massive reserves of methane in the subsea Arctic methane hydrates, that if only a few percent of them are disassociated, they will lead to a jump in the average temperature of the Earth's atmosphere by 10°C and produce a "Permian" style major extinction event which will kill us all. The whole northern hemisphere is now covered by a thickening atmospheric methane global warming veil that is spreading southwards at about 1 km a day and it already totally envelopes the United States. A giant hole in the equatorial ozone layer has also been discovered in the west Pacific which acts like an elevator transferring methane from lower altitudes to the stratosphere where it already forms a dense equatorial global warming stratospheric band that is spreading into the Polar regions.


During the last winter, the high Arctic winter temperatures and pressures have displaced the normal freezing Arctic Air south into Canada and the United States producing never before seen, freezing winter storms and massive power failures. When the Arctic ice cap finally melts towards the end of next year, the Arctic sea will be aggressively heated by the sun and the Gulf Stream. The cold Arctic air will then be confined to the Greenland Ice cap and the hot globally warmed Arctic air with its methane will flow south to the United States to further heat up the Gulf Stream, setting up an anticlockwise circulation around Greenland. Under these circumstances Great Britain and Europe must expect even more catastrophic storm systems, hurricane force winds and massive flooding after the end of next year due to a further acceleration in the energy transport of the Gulf Stream. If this process continues unchecked the mean temperature of the atmosphere will rise a further 8° centigrade and we will be facing global deglaciation, a more than 200 feet rise in sea level rise and a major terminal extinction event by the 2050's.

Ring Of Ice



Prominence of earthquakes in North America and around Greenland has prompted a team of researchers led by Arctic-news blog editor Sam Carana to coin the phrase “Ring Of Ice” to describe what they see happening in the Arctic.

“Melting of ice in north Canada and on Greenland is causing pressure changes, resulting in seismic activity”, explains Sam Carana.

Heavy seismic activity is ocurring along the faultlines that constitute the border of the North American Plate, similar to the the heavy activity along the Ring Of Fire around the Pacific Ocean.

Seismic activity roughly follows the borders of the North American Plate, which includes Greenland. However, where the major fault bends away to the west following the Aleutian Islands, seismic activity continues north through Alaska along a line that extends over the North Pole toward Svalbard.

This northward path through Alaska is illustrated by the earthquakes on the image below.


“Earthquakes are prominent along the entire border of the North American Plate”, Sam Carana adds, “but they increasingly appear to be taking this shortcut through Alaska and the underlying cause of this is melting of ice in north Canada and on Greenland”.

“This Ring Of Ice spells danger, just like the name Ring Of Fire indicates danger”, Sam Carana concludes. “The name Ring Of Fire warns about possible volcanoes, earthquakes, landslides and tsunamis. The Ring Of Ice seems even more dangerous, since seismic activity could destabilize methane hydrates contained in sediments under the Arctic Ocean, and could trigger huge methane eruptions. The fault line running from Greenland to Siberia is the most dangerous area on Earth in that respect”.

Warming waters threaten to trigger methane eruptions from Arctic Ocean seafloor

average surface temperatures, where black dots
are yearly averages. Two flat periods (hiatus)
are separated by rapid warming from 1976-1999.
(Middle) Observations of heat content, compared
to the average, in the north Atlantic Ocean.
(Bottom) Salinity of the seawater in the same
part of the Atlantic. Higher salinity is seen
to coincide with more ocean heat storage.
A new study looks at how, in the 21st century, surface warming slowed as more heat moved deeper into the oceans, specifically the North Atlantic.

Sun-warmed salty water travels north along ocean currents in the Atlantic. When this saltier water reaches the North Atlantic, its greater density causes it to sink. From about 1999, this current began to speed up and draw heat deeper into the ocean.

These huge amounts of heat moving deeper into the Atlantic Ocean are very worrying.

The image below shows that sea surface temperatures have reached extremely high levels on the Northern Hemisphere, where sea surface temperature anomalies as high as 1.78 degrees Celsius were recorded on August 19, 2014.

As discussed in an earlier post, water carried by the Gulf Stream below the surface can be even warmer than surface waters. As the post discusses, high sea surface temperatures west of Svalbard indicate that the Gulf Stream can carry very warm water (warmer than 16°C) at greater depths and is pushing this underneath the sea ice north of Svalbard. Similarly, warm water from greater depth comes to the surface where the Gulf Stream pushes it against the west coast of Novaya Zemlya.


Very warm water is now invading the Arctic Ocean through the Bering Strait from the Pacific Ocean, while very warm water is also traveling on the back of the Gulf Stream from the North Atlantic into the Arctic Ocean.


The danger is that this warm water will destabilize hydrates contained in sediments under the Arctic Ocean and trigger huge methane eruptions.

Rising methane levels over the past few years are ominous in this respect. The image below shows very high mean global methane levels on August 28, 2014, while methane readings as high as 2561 ppb were recorded on that day.

In conclusion, the situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog.

No new laws needed for President Obama to act

For anyone attending the September 23, 2014, Climate Summit in New York, it is important to bring the message that, while Congress may seek to deny the physical and legal realities, President Obama can and should act on climate change.


As you know, Sam Carana advocates comprehensive and effective action as discussed at the Climate Plan blog. You can share the message on facebook by clicking on the image below.
