Transition Update: Climate, Sea Level, and Weather

Carbon dioxide levels in the atmosphere reached 400 parts per million for the first time in 3 million years:

     Climate Milestone: Earth’s CO2 Level Passes 400 ppm

But something even more important might be emerging. For years, there have been some who predicted that when the Arctic sea ice melted, that the tremendous quantities of methane stored in the Arctic sea floor above Russia and North America would begin to be released into the atmosphere. The process would become an escalating feedback loop where the retracting ice reflected less sunshine back into space, the open water absorbed more sunlight, heating the water, forcing the ice to retract further, etc. Then the increasingly warming water would warm the sea floor, releasing the methane frozen there.

The methane release is considered to be important in the extreme because, as a greenhouse gas, methane is said to be twenty times more influential than carbon dioxide; and the amount of methane stored in the Arctic is said to have more heat-producing capacity than all of the other fossil fuels combined. Whether that quantity claim is perfectly accurate or not, it is agreed that there’s a lot of methane there.

The release of the methane would then accelerate the feedback loop by rapidly warming the atmosphere so that ultimately people would be calculating sea level rise in meters per decade rather than centimeters.

Now a multi-nation task force claims that there has been a dramatic increase in methane emissions in the Arctic. They say the process has recently escalated beyond their expectations. They believe a runaway feedback loop has likely begun and that the arctic could see an ice-free Summer by 2015 rather than the more generally-accepted predictions that this would not happen till sometime between 2030 and 2050.

Here’s an image showing, from left to right, the average minimum sea ice from 1979-2000; the previous record minimum set in 2007; and the new record set in 2012, from this link:


This gives an indication of the trend, though that trend also includes a persistent and significant thinning of the ice as well, which is not pictured.

Over the last year, those who monitor Arctic methane using aircraft flyovers say that large plumes of methane, some as wide as a kilometer, can be detected above both open Arctic sea water and cracks in the sea ice. This is a new development. Previously, only small plumes could be detected, and typically only near the Siberian coast where methane was escaping from melting permafrost on land. Strong methane emissions from the ocean floor can be seen in the 19 minute video Arctic Methane: Why The Sea Ice Matters. The video does an excellent job of explaining a lot of this and notes that, like many other places on the planet (see What is the Transition? Part 1), the Arctic is seeing an increase in seismic activity that could contribute to additional methane releases.

These folks are also studying how changes in the Arctic are causing or contributing to global weather extremes. While I was writing the What is the Transition series, one of the largest storms ever seen developed in the Atlantic, stretching from Canada to Portugal, Greenland to the Caribbean:

     Incredible North Atlantic storm spans Atlantic Ocean, coast to coast


Because there was no human body count, the mainstream media ignored it, so few heard about this late-March megastorm. It did contribute to unusually wintry weather in the UK, killing many animals there.

Saturn also had a mega-storm, so some of the energies we are encountering are likely related to our Solar System, not just our planet:

Back on Earth, the flooding from storms just keeps on coming:

     Update: ‘Tsunami of rain’ hits Buenos Aires – Death toll rises to 54 as millions left without power and water – Event was ‘deluge without historical precedent’

     Texas floods as up to seven inches of rain falls after storms hit much of the South

     Flash floods kill 16 in Saudi Arabia after heaviest rainfall in 25 years

     Evacuations ordered as flooding hits eastern France

     Nearly a foot of rain falls in Jackson County, Mississippi

     Death toll from north Afghanistan flash flooding rises to 20

     Record flooding threatens Midwest, Mississippi river

And John Stevanovic continues to produce monthly video summaries of weather extremes, earth changes, meteors, and so forth. I do not agree with his “end of the world” belief—as stated previously, I think we are in a major transition that will ultimately result in better times for humanity—but John’s videos do show compelling evidence of the accelerating turbulence that is contributing to the change we are experiencing:

And if you are reading this in mid-May, 2013, you might wish to check in daily with Sunspot AR1748 has already thrown off four X-class solar flares. Luckily, the CMEs (coronal mass ejections) from those flares have not been sent directly toward Earth, but the rotation of the Sun is bringing AR1748 into more direct alignment with the Earth in the coming days. Images of the four X-class flares are here.
