How the World was Wired

Posted by David on February 5th, 2008

If you’ve heard about the recent submarine cable outages, you might enjoy reading this fascinating 1996 article by science fiction genius Neal Stephenson on the first world-spanning fiber-optic network.  It includes some background on the brilliant and daring 19th century inventors and entrepreneurs who created the first world-spanning communications networks.  I’ve been reading it for the last nine hours, but I’m still not done because of all the historical and future (for 1996) places, technologies, and events it describes.

Brutal cold snap in Greenland

Posted by David on January 22nd, 2008

…a brutal cold snap is raging across the semi-autonomous nation of Greenland.On Disko Bay in western Greenland, where a number of prominent world leaders have visited in recent years to get a first-hand impression of climate change, temperatures have dropped so drastically that the water has frozen over for the first time in a decade.

Temperatures plunged to -25°C earlier this month, clogging the bay with ice and making shipping impossible for small crafts, according to Anthon Frederiksen, the mayor of the town of Ilulissat, where Disko Bay is located.

My point, as usual, is not to debate the facts of climate change, but to demonstrate the potential for a positive impact of a warmer climate for life on earth. A mayor in Greenland of all places, should be the first to welcome a warmer climate. Over 10 percent of the world’s land surface is permanently covered with ice, and much more is essentially lifeless due to seasonal ice. Imagine the possibilities if Greenland, an area slightly three times the size of Texas, and 81% ice-capped, was to actually become green.

How many lives is a billionth of a degree worth?

According to GM, the new federal fuel requirements will costs four to ten thousand dollars per car, mostly to use more expensive weight savings materials. Some environmentalists might dispute the numbers or cheer anything that makes cars more expensive to own, in the hope that fewer people are able to afford driving. However, that will not be the only impact.

If the amount the average person is willing to pay for a car does not change, people will respond to higher prices in two ways: they will keep their existing cars longer and buy cheaper cars. Keeping existing cars will delay the introduction of more efficient and luxurious cars in the future. Switching to cheaper, more efficient cars will increase efficiency at the cost of both luxury and safety. More families will be forced to squeeze into Honda Civics rather than Toyota Camry’s. Money that would have been spent on safety improvements will be diverted to increasing efficient. Smaller cars are not inherently unsafe, but they are inherently less safe, and thus the cost of the new fuel efficiency standards can be measured in both dollars and human lives. The cost in human lives of traffic accidents is well known – about 42 thousand lives each year in the U.S. How many people will the warming from the unspent gasoline kill? Actually, the oil not burned in cars will even not be “saved.” More efficient cars will simply make that oil available for other uses, which may or may not be more efficient.

Just how many lives is a billionth of a degree of global warming worth? Can we look forward to a new “no blood for freezing winters” campaign?

Global Warming Protest

Posted by David on January 18th, 2008

This is what a global warming protest looks like:

While ironic, this image does not prove anything. Except perhaps, that a weather few degrees below average can have a much more dramatic impact on human life than a few degrees above average.

Statism doesn’t sound as great when it comes to other fields, does it?

Mayor Thomas M. Menino embarked on a highly public campaign yesterday to block CVS Corp. and other retailers from opening medical clinics inside their stores… “Limited service medical clinics run by merchants in for-profit corporations will seriously compromise quality of care and hygiene. Allowing retailers to make money off of sick people is wrong.”

At least when it comes to biology.
