Singapore's Straits

Via Passport, a Foreign Policy blog, a Google Earth map showing the pile-up of cargo ships bobbing idly outside of Singapore.



It's a sign of the global economic times:
The world's busiest port for container traffic, Singapore saw its year-over-year volume drop by 19.6 percent in January 2009, followed by a 19.8 percent drop in February. As of mid-March 2009, 11.3 percent of the world's shipping capacity, sat idle, a record.
It's obviously a bad time to be a tiny city-state with few natural resources that's pretty much entirely dependent on trade for economic well-being:
The IMF projects that Singapore's economy will shrink significantly in 2009. Globally, bulk shipping rates have dropped more than 80 percent in the past year on weak demand, and orders for new shipping vessels are cratering. In Busan, South Korea, the fifth-largest port in the world, empty shipping containers are piling up faster than officials can manage.

Environmentalists vs. Environmentalists

The Natural Resources Defense Council has worked with Google to create a Google Earth mapping tool which shows environmentally sensitive areas of the American West.



The NRDC, like a lot of environmental groups, is especially concerned about the potential damage to wildlife and ecosystems of developing the region's prodigious energy potential. The irony is that much of this energy is in the form of wind and solar power - the very resources which need to be developed if we have any chance of doing anything about global warming. Obama has made some pretty bold moves to invest in those renewable energy resources in the west: a big chunk of the recent stimulus was devoted to building up the infrastructure that is sorely needed if that energy is to be brought to market.

The problem is that that infrastructure - the wind towers and solar panels, and all the high-voltage electrical lines that will connect them to the national grid - can cause problems for wildlife. From a New York Times article on the NRDC map:
The wind industry publishes photos of cows grazing placidly around towers, and argues it is compatible with nature. But Brian A. Rutledge, executive director of the Audubon Society of Wyoming, said wildlife and domesticated species were different. “We have species of birds, for example, that won’t nest within 200 yards of a road, period,’’ he said. Some prairie birds will not venture anywhere near a vertical object like a tower or a power-line pylon, he said, probably because they are genetically imprinted to avoid natural vertical features, like trees, where predators perch. The lesser prairie chicken, he said, will not cross under a power line, even between widely spaced towers. “It becomes like a river down the middle of their population base,’’ he said.
One such species is the sage grouse, the range of which sits right in the middle of an area where a lot of new transmission lines are likely to be needed.

As the Times puts it, the map amounts to the "battle lines being drawn" by the NRDC and like-minded organizations - a declaration of where they intend to fight development. It depicts areas that are prohibited, such as natural parks and wilderness areas, where devlopment is already prohibited; restricted areas, where rules on the books limit development, often because of threatened species; and "areas that should be avoided" - where, in other words, development may be permitted, but the NRDC is prepared to fight it.

I'm sympathetic to the NRDC, and we should all hope that development takes place in the most ecologically sensitive way possible, yadda yadda. But this framing, from the Times article, really seems to miss the forest for the trees (or the world for the forest):
And while the battle lines are quite literally available with a few mouse clicks, the intent is not entirely hostile, with the national groups recognizing that the issue is environmental balance, pitting prairie species like the greater sage-grouse against animals like the polar bear, which lives on ice that is melting because of global warming, some of it probably caused by coal-fired power plants that wind and sun could partly replace.
What a trivialization of what global warming is all about! Polar bears pulling a dodo is the least of our worries when it comes to global warming. It's not the sage-grouse vs. the polar bear; it's the sage grouse versus massive ecological calamity and the possible meltdown of entire ecosystems, not to mention famine and the mass dislocation of human populations. I'm all for sage or any other kind of grouses; but if legal wrangling over their protected status holds up the development of one of the few promising options we have for getting off of fossil fuels, then I will be mighty annoyed.

But because I am a fair man, I will let the sage-grouse have the last word. Here is a detail of their range from the Google Earth map.

Google Earth Map of CO2 Emissions in the US

This is a bummer:
A NASA satellite to track carbon dioxide in the Earth’s atmosphere failed to reach its orbit during launching Tuesday morning, scuttling the $278 million mission.

“It’s a huge disappointment to the entire team that’s worked very hard over years and years and really did their best to see it through,” said Charles P. Dovale, the launch manager. “The reason not everyone is able to do this is it’s hard. And even when you do the best you can, you can still fail. It’s a tough business.”
On the bright side, NASA and some Purdue scientists, working on something called the Vulcan Project, just launched a new Google Earth map that lets you see the amount of CO2 being emitted in the United States every hour. (The Purdue folks are the ones who put together this impressive map animation.) Here is a demonstration flyover:



It shows information about emissions at the state and county levels, and even gives information on specific source points, such as airports. It also breaks down emissions by sector, showing relative contributions from air traffic, electricity production, industry, commercial, transportation, and residential sources. It really does a good job of helping the viewer visualize carbon emissions - a sort of nebulous and abstract thing to try to think about - and that may prove to make it a very valuable tool in public efforts to decrease those emissions. You can download the Google Earth map at this site (though it ran a bit slow for me). And by the way, kudos to the Purdue folks for picking a badass name for their research project. You gotta know how to market this stuff, people!

Google Earth Adds Two-Thirds of Earth's Surface

According to the New York Times, Google Earth is adding oceans.


(That there is off the coast of Hawaii.)

It'll be interesting to see what kind of detail it has. Will you be able to see coral reefs? Sunken ships? Crabs hamming it up for the satellites?

Also this sounds cool:

Another feature, Historical Imagery, provides the ability to scroll back through decades of satellite images and watch the spread of suburbia or erosion of coasts.

You get the feeling that we're approaching a time when Google Earth provides real-time updates and multi-perspectival images of every point on Earth from point-blank range, a Google Aleph that will panoptically fulfill Larry Page and Sergei Brin's own personal god-dream.

Google Earth Blog has much more.
