Nobel Peace Prize Awarded for Work to Raise Awareness About Global Climate Change


Sentido.tv :: Climate change is no longer controversial; it has been accepted as scientific fact by a global consensus of researchers and policy makers, including the Bush White House, which resisted acknowledging human activities were a vital contributing factor, until recently. Now the Nobel committee selecting the Peace Prize laureate has raised the issue of warming posing a major international security crisis.

At a September conference he hosted on 'Energy Security and Climate Change', Pres. Bush acknowledged the validity of the IPCC's research, stating "A report issued earlier this year by the U.N. Intergovernmental Panel on Climate Change concluded both that global temperatures are rising and that this is caused largely by human activities. When we burn fossil fuels we release greenhouse gases into the atmosphere, and the concentration of greenhouse gases has increased substantially."

And now, the political class in the US liberal-conservative hot-bed must grapple with the fact that climate change will be, when its most serious repercussions are felt, an international security issue, pushing millions of refugees across borders in search of basic sustenance, like water and food. And policy-makers in the US must come to terms with their very real role in shaping the global capacity to confront these adverse consequences.

The Sudan is cited as a first-case. It's long civil war, in which the Khartoum-based regime fought against rebellions in the east, south and west of the country, had a lot to do with food and water scarcity, and the need to control natural resources like oil in order to have the wealth to import sufficient amounts of those vital commodities or to build needed irrigation. Khartoum would not allow local control in any part of the country. Further desertification, the "advance of the Sahara", threatens to return Sudan to multi-party civil war.

More global cases involve countries like China, India and Pakistan, three nuclear powers, which could find themselves engaged in a brutal life and death struggle to provide water to their immense populations, as snow-melt from the Himalayan Plateau becomes scarce. The world cannot afford to allow such a war, or its causes, to burst forth.

The IPCC, which shares the award with Mr. Gore, the world's most visible climate campaigner, has issued several reports this year alone putting top-line consensus climate science into the public domain and forcing governments to keep dealing with the issue publicly and diplomatically.

Clinton Global Initiative Brings Together 1,300, Including 52 Current or Former Heads of State


Former US pres. Bill Clinton's Global Initiative (CGI) holds a major international stakeholders' and donors' conference each year in conjunction with the UN's General Assembly, in New York City. This year's convention brings together 1,300 delegates from 72 countries. 52 active or former heads of state are participating, in only the 3rd year of this no-nonsense charity initiative.

'Members' contribute $15,000 in order to participate and must 'commit' to contributing or carrying out work of some concrete kind. They must come to the event with a plan already laid out and a clear agenda for enacting the plan. Political leaders, NGOs, business people, from around the world attend, with the aim of finding creative solutions to the world's most serious or deep-rooted problems. They must produce financial backing to bring their planned project to life before the following year's convention.

In order to ensure that the process is not just talk or debate, CGI requires as a condition of membership that those who do not follow through on their commitments be barred from attending the following year. Between the first and second conventions, 17 participants were not allowed back. Between the second and third (this year's), only five failed to return. The idea is to ensure that the event is not misused as a way to 'network' with powerful people, that its initiatives be a form of concrete progress and an example to other charitable endeavors.

The first two years of CGI raised over $10 billion for causes around the world, funding more than 600 'commitments' worldwide. The concept behind the initiative is to ensure that people with the conceptual and technical expertise have direct contact with the most influential backers to enact the kind of change needed specifically in certain areas.

As is prominently announced on the CGI website in a quote from Mr. Clinton, the idea is "to turn good intentions into real action and results". By building the requirement to follow through into the process of attending, proposal and planning, CGI has become an innovative example of effective global leadership, where interests come together and shared benefits can be both illustrated and made reality.

Geothermal Energy Creates Hope for Global Energy Solution


Sentido.tv :: Steam-driven process using deep underground vents to super-heat water could be 'nearly inexhaustible' resource...

The race to tap large quantities of underground, geothermal energy is heating up. In a recent bid to solve their country's demand for clean energy, the Swiss are digging deep, and the Earth is responding. A scientist at MIT, in the US, says 40% of US geothermal sources could power the entire country's energy needs in excess of 56,000 times.

At a cost of $51 million so far, the Swiss experiment in delving under the earth's crust has proven successful. The plan is to circulate water deep into the ground using shafts a bit larger than those used in drilling for oil, except pumping water and gaining access to high levels of heat, enough to harness the capacity to run a steam turbine and power an estimated 10,000 homes and offices.

The type of geothermal hot rock technology is called 'enhanced geothermal systems,' and drills into very hot granite at 400 degrees F. Even though the holes dug for these systems are deep, it only scratches the earth's surface and remains well away from the inner regions. 99% of the earth's interior is even hotter, at about 1000 degrees, where the technology is not designed to go, and where human science cannot yet reach without justfiable concerns about undesirable magma or gas leaks.

The science seems straighforward enough, but there may be a catch. In early December, the country registered a magnitude 3.4 tremor in response to Geothermal Basel's project to gain access to this untapped energy source. Coursing water through bored holes in the earth several miles deep has destabilized subsurface layers of crust causing shifts. The resulting tremors throughout the Basel region alarmed authorities enough to temporarily halt activity.

Clean and in ample supply, geothermal energy has the potential to power the current global population and much more without degrading the environment. The drawbacks include cost of drilling and stiff price competition from current fossil fuel extraction. Scientists say that certain hot rock source supplies, that cost about $7 to $8 million to drill, provide energy for only a limited amount of time, requiring a new source to be found after maybe just a decade.
