Accelerating Greenland Melting “Shocks” Scientists

Posted by in categories: biological, sustainability

The New York Times is reporting today that the continued acceleration of the rate at which the Greenland ice sheets are melting has scientists scrambling for answers. In particular, a combination of changes has the glaciologists particularly concerned. They say the accumulation of meltwater on the surface of the ice in the form of ponds and streams absorbs as much as four times more heat than the lighter-colored ice, thereby accelerating the surface’s rate of melting.

Additionally, this meltwater eventually finds its way to bedrock, where it appears to slightly lubricate the surface between ice and rock, facilitating more rapid ice shifting towards the ocean. A third factor in the trifecta is the breakup of substantial semi-submerged clots of ice that typically block narrow fjords. As these blockages break up, the flow of the frozen glacial rivers accelerates.

While there is still a tremendous amount about this cycle that remains undiscovered, what is clear is that the best estimates to date have fallen far short in terms of the speed at which these rare environments are changing. Although questions remain about how much of these changes are cyclical and how much is due precisely to man-originated global warming, we must gain a more complete understanding of these events so that we can take whatever steps we must to ameliorate any damage we’ve caused before the situation becomes so critical that massive changes come about as a result of our negligent handling of our environment.

Oil Surpasses $100 Per Barrel

Posted by in categories: geopolitics, sustainability

In an upward spurt that has been long predicted by the more realistic analysts, oil has finally broken through the triple digit threshold. While some experts maintain that this number is little more than a psychological barrier and has little real-world importance it is an inescapable fact that oil prices themselves have actually increased approximately 73% in the past year.

This price increase alone should be a call to action sufficient to bring us to a state of alert yet it appears that the general population remains relatively complacent in the face of this looming crisis. It should be noted by those of us more aware of the ramifications of peak oil and the impending oil supply shock that such a drastic reduction in oil availability represents one of the clearest and most present threats to the stability of a global peace and the longevity of mankind.

As with all threats of a global nature, the Lifeboat Foundation will continue to monitor news related to oil reserves, prices, supply and of course replacement technologies and continue to provide information, perspective and solutions.

The Enlightenment Strikes Back

Posted by in categories: complex systems, futurism, geopolitics, lifeboat, nanotechnology, open access, sustainability

In a recent conversation on our discussion list, Ben Goertzel, a rising star in artificial intelligence theory, expressed skepticism that we could keep a “modern large-scale capitalist representative democracy cum welfare state cum corporate oligopoly” going for much longer.

Indeed, our complex civilization currently does seem to be under a lot of stress.

Lifeboat Foundation Scientific Advisory Board member and best-selling author David Brin’s reply was quite interesting.

Aerospaceplanes and space solar power

Posted by in categories: habitats, space


Supplying a substantial percentage of America’s future electrical power supply from space using SBSP (space-based solar power) systems can only be expressed as a giant leap forward in space operations. Each of the hundreds of solar power satellites needed would require 10,000–20,000 tons of components transported to orbit, assembled in orbit, and then moved to geostationary orbit for operations. The scale of logistics operations required is substantially greater than what we have previously undertaken. Periodically, industrial operations experience revolutions in technology and operations. Deep sea oil exploration is an example. Within a couple decades, entirely new industrial operations can start and grow to significant levels of production. The same will happen with space industrialization when—not if—the right product or service is undertaken. SBSP may be the breakthrough product for leading the industrialization of space. This was our assumption in conducting the study. As the cost of oil approaches $100 a barrel, combined with the possibility of the world reaching peak oil production in the near future, this may turn out to be a valid assumption.

Helphookup.com internet empowered volunteers against disasters

Posted by in categories: defense, existential risks, futurism, lifeboat, open access, open source, sustainability

The inspiration of Help Hookup is actually a comic book called Global Frequency by Warren Ellis. My brother, Alvin Wang, took the idea to startup weekend and they launched the idea this past weekend for hooking up volunteers. It is similar to the concepts of David Brin’s “empowered citizens” and Glenn Reynolds “an army of Davids”. The concepts are compatible with the ideas and causes of the Lifeboat foundation.

Global Frequency was a network of 1,001 people that handled the jobs that the governments did not have the will to handle. I thought that it was a great idea and it would be more powerful with 1,000,001 people or 100,000,001 people. We would have to leave out the killing that was in the comic.

Typhoons, earthquakes, and improperly funded education could all be handled. If there is a disaster, doctors could volunteer. Airlines could provide tickets. Corporations could provide supples. Trucking companies could provide transportation. Etc. State a need, meet the need. No overhead. No waste.

The main site is here it is a way for volunteers to hookup

The helphookup blog is tracking the progress.

Social Software Society for Safety

Posted by in category: futurism

Social Software Society for Safety.

Is there any scarcity? Perhaps friendship, because it requires time, shared history, and attention, is the ultimate scarcity—but must it always be the case?

A thoroughgoing naturalist, I stipulate that the value of all objects supervenes on their natural properties—rational evaluation of them is constrained by the facts. If I choose one car instead if its identical copy, simply because one has been stamped with a “brand,” this is the very definition of irrationality—if the 2 objects are exactly the same—you must be indifferent or violate the axioms of decision theory/identity theory. If I used a Replicator Ray to duplicate the Hope Diamond—which would you choose—the original—based on its history (was stolen, traveled around the world, etc) or the duplicate—they are identical!!

What happens to the value of the original? It is worth ½ because now there are 2? I make a 3rd copy so now it is worth 1/3? Nonsense—value has nothing to do with scarcity—a piece of feces may be totally unique in shape, just like a snowflake—but it has no value. Intrinsic value of objects depends on their properties. Instrumental value depends on what they can be used for (converted to intrinsic value).

Yellowstone Caldera Rising

Posted by in category: existential risks

The Yellowstone caldera has moved upwards nine inches over the last three years, a record rate since geologists first began taking measurements in the 1920s. This is the result of a Los Angeles-sized blob of magma that recently rose up into the chamber only six miles below the surface. The Yellowstone caldera is an ancient supervolcano. Last time it erupted, 642,000 years ago, it ejected 1,000 cubic kilometers of magma into the air. If this happened in today’s world, it would kill millions and cover most of the United States in a layer of ash at least a centimeter thick. The lighter ash would rise up into the atmosphere, initiating a volcanic winter and ruining crops worldwide.

Calderas rise and fall worldwide all the time without erupting. But the activity in Yellowstone is still concerning. Like a reckless teenager in a sports car, it seems as if our civilization laughs off the possibility of its own demise like a complete joke. Yet the right sort of event, and we could be knocked flat. Instead of waiting for a disaster to happen, we should prepare in advance to minimize its probability.

I would like to see scientists do a study on the feasibility of using nuclear weapons to initiate a supervolcano eruption. If it looks feasible, then park security in Yellowstone should be increased.

Rioting at the Foresight Unconference

AP, Nov. 3 — The Foresight Unconference announced today that scientists have discovered that there in no world below 1 nanometer. “It’s just space,” said noted scientist Eric Drexler. “We don’t know what to do!” Participants left dazed. Many decided to go back to philosophy, one attendee said.

“Like I said, It’s full of stars!” said novelist Arthur C. Clarke, reached in Sri Lanka. “There’s no there, there.”
