As West Antarctica melts, the urgency for climate change adaptation rises; but the decline of democracy gets in the way

My sister, Delwyn, sent me the article below about the increasing rate of loss of Antarctic ice.  Its scary.  Just about every major city stands to be inundated within 50 to 100 years and countries like bangladesh are threatened with oblivion.  Cities like London, Miami, New York, Brisbane and Jakarta face catastrophe.  And, it appears the collapse of Antarctic ice has passed the tipping point, meaning that sea level rise in the magnitude of meters is inevitable.  There is nothing we can do.  But that does not mean there is nothing we can do to at least slow the rate of sea level rise and mitigate the social and environmental damage.

You might wonder why there has been little in the way of actual change?  After all, we are continuing to burn fossil fuels more than ever and there is no sign of letup in the next 50 years.  Why, despite all the evidence that burning fossil fuel is the number one culprit leading to global warming?  Why is it that the climate change denialists, like the tobacco industry, have managed to hold so much sway over decision makers in the face of overwhelming scientific evidence?  

The reason: because we, the people of the World, have little or no influence over what our Governments actually end up doing.  Wealth, power and influence is concentrated in the hands of about 1% of the population - they have the say.  Don't believe me?  Well the science is there proving that we are run by oligarchies - not democracies.  I have linked an article below from Princeton University on the subject.  Even countries like New Zealand, which are supposedly more democratic than most, have recently been rocked by revelations of wealthy individuals receiving favoured attention by Ministers of the Crown.  New Zealand is now more like an oligarchy than a democracy.

Its time to hit the Governments' Reset Buttons to restore democracy to one citizen - one vote, while banishing the buying of  political influence while severely clipping the wings of snooping agencies such as the NSA which have clearly exceeded their role of securing our safety and freedom.  Do these and we might just see some real action on the things that really do matter to the majority of people.

Please read the two articles below and you are welcome to add your comments to this blog, thanks.


As West Antarctica melts, the urgency for climate change adaptation rises

As if the recent reports from the Intergovernmental Panel on Climate Change (IPCC) and the National Climate Assessment (NCA) weren’t enough of a reminder of the ways in which human actions are changing our planet, new research published in the current edition of Geophysical Research Letters (GRL) presents evidence that part of the West Antarctic Ice Sheet has passed a tipping point. The glaciers in the Amundsen Sea sector of West Antarctica are melting at an unprecedented rate, they’ll be gone within the next few centuries, and there’s nothing we can do to stop their disappearance. These glaciers contain enough ice to raise the global see level by 4 feet (1.2 meters), and even if it takes two centuries, that’s still one foot of sea level rise every 50 years. These are the sorts of findings that take your breath away, or at least they did ours.

Princeton Concludes What Kind of Government America Really Has, and It's Not a Democracy

A new scientific study from Princeton researcher Martin Gilens and Northwestern researcher Benjamin I. Page has finally put some science behind the recently popular argument that the United States isn't a democracy any more. And they've found that in fact, America is basically an oligarchy.
An oligarchy is a system where power is effectively wielded by a small number of individuals defined by their status called oligarchs. Members of the oligarchy are the rich, the well connected and the politically powerful, as well as particularly well placed individuals in institutions like banking and finance or the military.
For their study, Gilens and Page compiled data from roughly 1,800 different policy initiatives in the years between 1981 and 2002. They then compared those policy changes with the expressed opinion of the United State public. Comparing the preferences of the average American at the 50th percentile of income to what those Americans at the 90th percentile preferred, as well as the opinions of major lobbying or business groups, the researchers found out that the government followed the directives set forth by the latter two much more often.
It's beyond alarming. As Gilens and Page write, "the preferences of the average American appear to have only a minuscule, near-zero, statistically non-significant impact upon public policy." In other words, their statistics say your opinion literally does not matter.
That might explain why mandatory background checks on gun sales supported by 83% to 91%of Americans aren't in place, or why Congress has taken no action on greenhouse gas emissions even when such legislation is by the vast majority of citizens.

Interview with Delwyn Moller, NASA Glacier and Ice Surface Topography research scientist

Delwyn, flanked by Lorraine and Gordon (2009)
My Gosh!  The things people from Putaruru get up to....

Help!  Is there someone out there who can post a plain English summary of this article for the rest of us, thanks.

5/2/2013 - EIELSON AIR FORCE BASE, Alaska -- A team of researchers from the NASA Airborne Science Program recently visited Eielson to assemble topography of glaciers and ice sheets in Alaska April 25 to 27, 2013.

Due to some of the research taking place in the Beaufort Sea, Eielson's location provided NASA with necessary personnel and equipment to achieve mission objectives.

"This NASA mission is just another example of how Eielson's unique location, capacity and support infrastructure can be leveraged to support and enable a myriad of [Department of Defense] and federal organization's missions," said Robert Cologie, 354th Operations Support Squadron current operations flight commander. "The NASA support distinctly captures the cornerstone essence of Team Eielson's prepare, enable and deploy skillset."

NASA's team developed a radar system capable of generating wide-swath, precise digital elevation models of glaciers and ice sheets. Aptly named GLISTIN-A, Glacier and Ice Surface Topography Interferometer-Airborne, this sensor collects glacier measurements and sea ice observations.

"Specifically, the GLISTIN-A sensor ... contributes high accuracy, high resolution swath measurements in targeted regions that are topographically and dynamically complex," said Delwyn Moller, NASA Jet Propulsion Laboratory. "The sea ice acquisitions are a test of the sensor's capabilities and potential to measure freeboard and are the first measurements of this kind."

To obtain images from the sensor, GLISTIN-A is attached to a NASA C-20A aircraft. The aircraft, obtained from the Air Force in 2003, has been structurally modified and instrumented by NASA's Dryden Flight Research Center to serve as a multirole, cooperative research platform.

The mission to Alaska focused primarily on tidal glaciers, which have a more direct contribution to sea level rise, in order to potentially seed larger-scale observations in other campaigns for climate change science, Moller said.

"Sea ice is just one factor in studying climate change, but it is a major indicator of a warming climate," she explained. "GLISTIN-A has a potential to map and monitor the distribution and mass of the sea ice in a way not currently available through alternate space-borne or airborne sensors."

With the success of the mission to Alaska and the support received from the Iceman Team, members of the C-20A crew are excited to return to the Interior in the future.

"We spend a lot of time at Air Force bases and international airports across the globe, receiving the necessary ground support that is needed to make our missions a success," said John McGrath, C-20A project manager. "The help we have received from everyone here at Eielson is by far the best we have ever experienced and has made our lives very easy and our mission a success, and we are looking forward to coming back up here again."

Latest News About Global Warming

George Bush denies it, US Government scientists are not allowed to use the term "global warming" when referring to glacial recession and extreme weather events like Hurrican Katrina. Australian PM, John Howard still claims that the jury is still out on the influence of man on global warming. Meanwhile, his country burns and its cities begin to run out of water. Can we afford to be so selfish and complacent in the face of what is overwhleming evidence of the hand of Man in accelerated warming of the planet? I think not.

Keep informed and up to date with developments that might see the end of civilisation as we know it. Better still, act locally as well as globally by reducing your environmental footprint.
