The 4th degree

Artw — Sun, 10 Aug 2008 17:38:04 -0800

80 percent of Americans say global warming is real and poses a threat to humanity. Which is good because if the global temperature raises by 4 degrees we're all dead. However only 44 percent would be willing to face any financial hardship in the name of a solution.

There Could Be Blood

Andy Grove on Our Electric Future - "Energy independence [viz.] is the wrong goal. Here is a plan Americans can stick to." Perhaps some infrastructure spending^1,2 is in order? [etc., &c., cf.] also see :P - "Tesla Motors Is Delivering Cars" - "Superconducting Power Grid Launches In New York" - "New heights reached in polymer based solar cell efficiency"

[S]pray a sheet of glass with a mixture of dyes combined with a substance called tris(8-hydroxyquinoline) aluminium. In combination, the dyes and the glass act as the waveguide, preventing light from escaping. Meanwhile, the interaction between the different dye molecules and those of the tris(8-hydroxyquinoline) aluminium allows a quantum-mechanical phenomenon, called Förster energy transfer, to come into play. This eliminates the reabsorption loss by ensuring that light is re-emitted at a frequency which the dye molecules cannot then reabsorb. On top of this—literally—Dr Currie and Dr Mapel have come up with another trick: placing a second sandwich of dye and glass over the first. The upper layer of dye intercepts high-energy light, such as ultraviolet. The lower one captures longer wavelengths that have passed unperturbed through the upper, and also any lower-energy light that has been re-emitted within the top layer and somehow escaped. The upshot is a device that, even as a prototype, converts ten times more of the incident light into electricity than a conventional solar cell. [and btw]

US Eastern Seaboard the spillway for a "slow wave" of melting Greenland glaciar water

stbalbach — Tue, 08 Jul 2008 10:28:38 -0800

Melting Greenland glacier water forms a "slow wave" that stays in the Atlantic for at least 50 years before reaching the Pacific, according to a new study. The water piles up in the Atlantic. "It is often assumed that sea levels will rise instantaneously, but that is unlikely, given what we know about ocean dynamics." Fifty years after the meltwater is released from Greenland, sea-level rise could be 30 times greater around Greenland and down the eastern side of North America, including the Gulf of Mexico, than in the Pacific Ocean. Sea-level rises in Europe are around six times that of the Pacific, but only a fifth as great as on the opposite shore of the Atlantic.

Lester Brown's Plan B 3.0

In Lester R. Brown's new book Plan B 3.0: Mobilizing to Save Civilization (2008, full-text)) - an update to Plan B 2.0: Rescuing a Planet Under Stress and a Civilization in Trouble (2006, full-text) - he calls for a war-time mobilization (ch.13) to save global civilization (already showing Early Signs of Decline (ch.6)) from Deteriorating Oil and Food Security (ch.2), Rising Temperatures and Rising Seas (ch.3), Emerging Water Shortages (ch.4), and Natural Systems Under Stress (ch.5)

World's Biggest and Most Expensive Ship

Project Genesis - "It's destined to be the world's largest cruise ship—when launched next year, Royal Caribbean's US$1.24 billion Project Genesis will be 1,180 feet long, and carry 5400 passengers (6,400 at a pinch). It's the most expensive ship in history, and it's longer, wider and taller than the largest ocean liner ever built, (Cunard's QE II), 43 per cent larger in size than the world's largest cruise ship, (Freedom of the Seas [previously]) and remarkably, bigger than any military ship ever built, aircraft carriers included. In a world where choice of amenities count, Project Genesis has yet another trump card—in the the center of the ship is a lush, tropical park which opens to the sky." cf. The Lilypad

Abrupt climate change

stbalbach — Fri, 20 Jun 2008 08:03:51 -0800

Abrupt climate change is popularly thought of in the movies. But new Greenland ice core findings show two huge Northern Hemisphere temperature spikes occured prior to the close of the last ice age some 11,500 years ago, with a 22-degree-Fahrenheit spike in just 50 years. These followed a massive "reorganization" of atmospheric circulation taking just one or two years. "We know such events are in Earth's future, but we don't know when .. we are speeding blindly down a narrow road, hoping there are no curves ahead." GBN (Global Business Network) released a scenario report in 2004 for the Department of Defense: "An Abrupt Climate Change Scenario and Its Implications for United States National Security."

New Kiribati

New Kiribati "...will future climate change refugees become a new caste of service sector workers inhabiting a sort of Floating Hotel & Duty Free Mall ... ?" Small island states are on the front line.

A number we can live with

Today marks the official 8-language launch of 350.org and the start of global action against climate change. But what does this 350 number even mean? As author Bill McKibben and a c h o r u s of scientific voices suggest, it means everything to the planet. If we want an earth at all, we'll need an Earth at 350.

End of the World? ABC wants your ideas

stbalbach — Fri, 13 Jun 2008 08:14:46 -0800

Earth2100.tv is a project by ABC (video preview) to solicit ideas from the public and experts about the dangers facing world in the next 100 years. "The world’s brightest minds agree that the “perfect storm” of population growth, resource depletion and climate change could converge with catastrophic results. We need you to bring this story to life."

Inconvenient Truths: Get Ready to Rethink What It Means to Be Green

Inconvenient Truths: Get Ready to Rethink What It Means to Be Green. Last month, Wired published what it called "10 green heresies" which makes the case for urban living, intensive forest management and, er, air conditioning, among other things.
