As Arctic Ocean warms, megatonnes of methane bubble up

As the mother of two young boys, I began to think it a bit crazy that I attended to every bump and scrape on my children's little bodies and budding egos, but largely ignored the threat likely to put sizeable areas of the world, including parts of the coastal city where we live, underwater within their lifetime.

Dear fellow Earth citizens,

Here again are a couple of news stories I really hope will convince those that care about life on Earth that taking real and tangible action is urgently needed!

And that clearly starts with our on eco-footprint, a more sustainable lifestyle and support of Fair Trade and other social and economic justice issues - no matter, what the self-serving BS of the "everything is just so wonderful" (bingo - no need to take action!) and "sending out love and kindness is enough" (voilĂ  - no behavioral and lifestyle changes required!) faction may claim...

It also means to at least starting to think about what to do when (read: before) things get real dicey. And clearly, that can only mean teaming up with others because only a concerted effort on the part of many will make sure that some of us will be able to live instead of just surviving towards the end of this century!

1) As Arctic Ocean warms, megatonnes of methane bubble up - It's been predicted for years, and now it's happening. Deep in the Arctic Ocean, water warmed by climate change is forcing the release of methane from beneath the sea floor. Over 250 plumes of gas have been discovered bubbling up from the sea floor to the west of the Svalbard archipelago, which lies north of Norway. The bubbles are mostly methane, which is a greenhouse gas much more powerful than carbon dioxide.

None of the plumes the team saw reached the surface, so the methane was not escaping into the atmosphere and thus contributing to climate change – not in that area, at least. Bigger bubbles of methane make it all the way to the top, but smaller ones dissolve. Just because it fails to reach the surface doesn't mean the methane is harmless, though, as some of it gets converted to carbon dioxide. The CO2 then dissolves in seawater and makes the oceans more acidic.

If methane began escaping at similar rates throughout the Arctic, it would dramatically increase methane levels in the atmosphere.

Note: And all that methane released into the atmosphere puts us ever closer to irreversible tipping points....

Phytoplankton Threatened by Climate Change - Populations of Antarctic phytoplankton have dropped significantly due to global warming, threatening the entire chain of ocean life, according to a study conducted by researchers from Rutgers University and published in the journal Science.

Phytoplankton are microscopic plants that form the bottom of the oceanic food chain; they are fed upon by krill, which are eaten by whales and small fish. Small fish are then eaten by larger animals all the way up the chain to Adelie penguins and other macro fauna.

Illegal logging - Illegal logging is depleting global forests at an alarming rate, in a smuggling operation that is “better than drug smuggling”. Trafficking some rain forest woods through cities such as Singapore can be just as profitable as trafficking cocaine or heroin without the severe penalties.

This is a multi-billion dollar black market industry that is taking place under the noses of government officials in more than 70 countries around the world, and has so far, been responsible for the destruction of more than 32 million acres of forest. That’s roughly the equivalent area of the state of New York.

Forests absorb some 20% of the earth’s carbon dioxide output, and when they are no longer there, decaying vegetation releases carbon dioxide directly into the atmosphere. In recent years, deforestation has been responsible for a greater amount of carbon dioxide emissions than all forms of transportation combined.

GMO Scandal: The Long Term Effects of Genetically Modified Food on Humans - An editorial in the respected American scientific monthly magazine, Scientific American, August 2009 reveals the shocking and alarming reality behind the proliferation of GMO products throughout the food chain of the planet since 1994. There are no independent scientific studies published in any reputed scientific journal in the world for one simple reason. It is impossible to independently verify that GMO crops such as Monsanto Roundup Ready Soybeans or MON8110 GMO maize perform as the company claims, or that, as the company also claims, that they have no harmful side effects because the GMO companies forbid such tests!

As a precondition to buy seeds, either to plant for crops or to use in research study, Monsanto and the gene giant companies must first sign an End User Agreement with the company. For the past decade, the period when the greatest proliferation of GMO seeds in agriculture has taken place, Monsanto, Pioneer (DuPont) and Syngenta require anyone buying their GMO seeds to sign an agreement that explicitly forbids that the seeds be used for any independent research. Scientists are prohibited from testing a seed to explore under what conditions it flourishes or even fails. They cannot compare any characteristics of the GMO seed with any other GMO or non-GMO seeds from another company. Most alarming, they are prohibited from examining whether the genetically modified crops lead to unintended side-effects either in the environment or in animals or humans.

The only research which is permitted to be published in reputable scientific peer-reviewed journals are studies which have been pre-approved by Monsanto and the other industry GMO firms.

5) Book review:
Waste The True Cost of What the Global Food Industry Throws Away - The world has a 'food problem' - rapidly rising prices, shortages, 100 million people starving, environmental depredation - or it thinks it does. This book shows that farmers, manufacturers, supermarkets and consumers in North America and Europe discard between 30 and 50 per cent of their fresh produce - enough to feed the starving in the world six times over. Additionally, while affluent nations throw away food through neglect, up to 40 per cent of some crops in the developing world are wasted because farmers lack the basic infrastructure to process and store them before they rot.
