Scientists last week published a paper claiming that the Fukushima nuclear reactor meltdown caused 14,000 U.S. deaths.

Junk science: Scientists last week published a paper claiming that the Fukushima nuclear reactor meltdown caused 14,000 U.S. deaths. You can download the paper here [pdf].

I expect the mainstream television press to push this story in the coming days. The story however is crap. I’ve read the paper, and all it shows is a small statistical increase in deaths in the fourteen weeks after the earthquake/meltdown, compared to the previous year. The scientists provided no context with other years, nor did they factor in changes in total population or a host of innumerable other variables that would influence these numbers. Worse, they presented no direct evidence linking the fallout from the meltdown with the deaths.

In other words, this is agenda-driven science, designed mainly to attack nuclear energy. We should not give it much credence.

One more point: the lead author of the paper is the executive director of Radiation and Public Health Project, an organization whose only purpose appears to be to prove that low level radiation has a negative effect on human health. From a science perspective, this is not a good way to do science. The only way the scientists in this organization can justify their fund-raising and research is to find evidence to prove their theory.

The Fukushima nuclear reactor has reached the state of cold shutdown

10:06 am

Good news: The Fukushima nuclear reactor has reached the state of cold shutdown.

This means that the reactor core has cooled enough that there is no need to recirculate the water to keep the fuel cool. However, because the reactor continues to leak that water recirculation is still necessary, and will be for years.

As is typical of many modern journalists, the article above is also an unstated editorial both hostile to nuclear energy as well as private enterprise, best shown by the article’s concluding paragraph:

Meanwhile, the Japanese public and many of its politicians remained deeply mistrustful of the situation at Fukushima. In this week’s issue of Nature, two members of the Japanese parliament call for nationalization of the Fukushima Plant, to allow scientists and engineers to investigate exactly what happened inside the reactors, and to reassure the public that the decommissioning will be done with their interests at heart. Regardless of whether you agree with the authors, nationalization seems almost inevitable. The lengthy decommissioning process that will follow this cold shutdown, and the enormous cost involved, make it a job for a government, not a corporation. [emphasis mine]

First, he has no idea what the Japanese public thinks of this situation. Second, there is no evidence that the government could do this job better than the company that runs the reactor. Both conclusions are mere opinion, inserted inappropriately in a news article without any supporting proofs.

Akatsuki’s engine too damaged to put the probe into Venus orbit in 2015

9:23 am

The engine of Japan’s troubled Venus probe, Akatsuki, has been found too damaged to put the probe into Venus orbit.

JAXA conducted a test ignition of the probe’s main engine on Wednesday to prepare for another attempt to send it into orbit in 2015. But the thrust produced was only one-eighth the amount anticipated, the space agency said. The damage the engine suffered last December when JAXA ignited it in the initial attempt to send the probe into orbit around Venus appears to be more serious than thought, JAXA said.

Private Japanese weather company to launch satellite to track Arctic Ice

9:14 am

A private Japanese weather company plans to launch a satellite to track Arctic ice for use by shipping.

The satellite will transmit images and information about sea ice in the Arctic Ocean. Weathernews will combine the information with available data on sea currents, weather and wave height to provide consumers with a finished product enabling safe navigation along the northern route.

Though I know most people are skeptical of this idea, I think that all weather information should be gathered and sold by private companies, as Weathernews is doing above. For example, the Weather Channel makes its money providing weather information to the public. If they didn’t get the satellite data free from NOAA weather satellites, they would have every reason to launch their own satellites.

Atmosphere Above Japan Heated Rapidly Before M9 Earthquake

2:43 pm

New satellite data shows that the atmosphere above Japan heated rapidly in the days before the March earthquake.

The [researchers] say that before the M9 earthquake, the total electron content of the ionosphere increased dramatically over the epicentre, reaching a maximum three days before the quake struck. At the same time, satellite observations showed a big increase in infrared emissions from above the epicentre, which peaked in the hours before the quake. In other words, the atmosphere was heating up.

New York Metropolitan Opera stars, fearing radiation, skip Japan tour

9:43 am

Cowards: Two New York Metropolitan Opera stars, fearing radiation, have backed out of a Japanese tour in the cities of Tokyo and Nagoya. This, despite the documented lack of radiation:

Tokyo briefly registered nominally higher radiation levels in its air and water, but they have subsided to pre-tsunami levels. There was never any scientific concern of a radiation impact on Nagoya, which is much farther away.

Meanwhile, the efforts to stabilize the reactors in Fukushima are proceeding.

Japan’s tsunami waves top historic heights

12:46 pm

Japan’s tsunami in March produced the largest waves in history.

Some waves grew to more than 100 feet high, breaking historic records, as they squeezed between fingers of land surrounding port towns.

To me, however, this is the biggest takeaway:

Although terrible, the preliminary estimate also finds a better-than 92% survival rate for people living in coastal towns hit by the waves, Bourgeois says. “In that sense, given the magnitude of the unexpectedly large earthquake, things could have been even worse,” she says.

The real disaster in Japan

12:10 pm

Getting control of the nuclear power plant in Fukushima is going to be a challenging job, no doubt. Nonetheless, it remains a minor and comparatively trivial problem for Japan after the earthquake and tsunami destroyed the country’s northeastern coast, and it saddens me that so much of the American press and public seems unable to absorb this simple fact.

This footage of the tsunami hitting a small coastal town in Japan gives us a clear and unvarnished look of the real disaster there. Near the end you can see people fleeing for their lives, and throughout the video the voices of the watchers can only express horrified gasps at what they are seeing.
