Water and ice at the bottom of the Antarctic Ice Sheet
The uncertainty of science: Unexpectedly large amounts of flowing water and refrozen ice found at the bottom of the Antarctic icecap. Key quote:
It’s too early to know whether this new finding means that global warming will melt ice sheets slower or faster than scientists have predicted. But the work does suggest that current models of ice sheet dynamics are missing a huge factor, said glaciologist Donald Blankenship of the University of Texas, Austin. “The take-home message of this work is that [the bottom of ice sheets] can no longer be ignored” in the models, he says.
More press release journalism,
this time about sunspots
Did you hear the news? Scientists have solved the mystery of the missing sunspots!
You didn’t? Well, here’s some headlines and stories that surely prove it:
- From Space.com: Mysterious Case of Missing Sunspots Solved.
- From Reuters: Scientists solve mystery of disappearing sunspots.
- From the Deccan Herald: NASA, India sponsored research explains missing sunspots.
- From Wired: Study Blames Plasma Flow for Spotless Sun.
- From NASA: Researchers Crack the Mystery of the Missing Sunspots.
- From Montana State University: MSU team solves mystery of missing sunspots, helps predict space weather.
- From Harvard-Smithsonian Center for Astrophysics: Solar Mystery Solved.
The trouble is that every one of these headlines is 100 percent wrong. The research, based on computer models, only found that when the plasma flow from the equator to the poles beneath the Sun’s surface slows down, the number of sunspots declines.

Traffic and more roads
Puncturing the myth that more roads mean more congestion Key quote:
Read enough of these studies and you get a sense that much of the induced-demand hubbub is really a sub rosa extension of the war on the suburbs: Stop highway expansion and you can make life miserable enough for the minivan-driving masses that they’ll move out of their gauche “urban-fringe developments” and back to high-density metropolitan cores, where they belong.
In reading the full essay, I was struck by how much the scientific campaign against road construction reminded me of climategate.

Northern Lights
An evening pause: When the Sun gets active, such as the solar flare of February 15, 2011, the sky in the high latitudes gives us the world’s best light show.
The caves of Copernicus
and the Ocean of Storms
The discovery of new caves on the Moon keep coming. Today I have two new stories. The first is a discovery by professional scientists of a giant lava tube cave in the Oceanus Procellarum or Ocean of Storms. The second is the detection of a plethora of caves and sinks on the floor of the crater Copernicus, found by a NASA engineer who likes to explore the gobs of data being accumulated by Lunar Reconnaissance Orbiter and made available to all on the web.
The image below of the Moon’s near side, taken by India’s Cartosat-2A satellite and taken from the science paper, shows the location of lava tube in Oceanus Procellarum (indicated by the red dot) and the crater Copernicus.
First the professional discovery. Yesterday, the Times of India reported the discovery of lava tube more than a mile long on the Moon. I did not post a link to the article because I didn’t think the news story provided enough information to make it worth passing along. Today however, fellow caver Mark Minton emailed me the link where the actual research paper could be downloaded [pdf]. This I find definitely worth describing.

Two High-priority Climate Missions Dropped from NASA’s Budget Plans
Two high-priority climate missions dropped from NASA’s budget by the White House. And what’s most amazing: No one’s squealing!
“Removal of these missions was not what we desired and not what the administration desired, but it was a clear recognition and acknowledgement of the budget issues we face as a nation,” [said Steve Volz, associate director for flight programs at NASA’s Earth Science Division]. “It’s cleaner to be allowed to delete the scope that goes along with the dollars than to have to figure out how to do more with less.”
Detector Array Deterioration Poses New Problem for JWST
More problems for the James Webb Space Telescope: The detector arrays for several instruments are deteriorating, even as they sit on the shelf. And remember, the 2014 launch date is probably going to be delayed until 2016. Key quote:
“As you get further and further out with [the launch date], it really raises questions about how far down the [integration and test] process you go for the instruments … and how long you have to store all that before you actually launch,” [Webb program director Rick Howard] told the NASA Advisory Council’s astrophysics subcommittee during a Feb. 16 public meeting here. “And that just makes everybody even more nervous about this problem than anything else.”
Another climategate whitewash
The inspector general of the Department of Commerce has just issued a review of NOAA’s response to the climategate emails and has essentially given the agency a clean bill of health. You can download the full report here [pdf].
It’s. just. another. whitewash. Let me quote just one part of the report’s summary, referring to a Freedom of Information Act (FOIA) request to NOAA in June 2007 in which the agency responded by saying they had no such documents:

Researchers have uncovered the oldest cremated human remains ever discovered in northern North America at a site in central Alaska
Scientists have uncovered the oldest cremated human remains ever discovered in northern North America at a dig site in central Alaska. Key quote:
Archaeologists discovered the remains last spring in a fire pit in an abandoned living area from 13,200 years ago and dated the child’s death to about 11,500 years ago.
The squealing of a former Bush science administrator
The cries and squeals are now coming from all sides: A former undersecretary for Science in the Energy Department during the Bush administration, Raymond L. Orbach, has joined the chorus of scientists whining about the House’s proposed cuts. [His full editorial, available here as a pdf, can only be downloaded if you subscribe to Science.]
Like all the other squealers, he admits that “the budget deficit is serious.” Nonetheless, the idea of cutting his pet science programs remains unacceptable.
It is when I read stuff like this that feel the situation is most hopeless. Is there no one willing to accept the reality that if we don’t start gaining some control over the federal budget the country will go bankrupt and we will not be able to afford anything?
Instead, all I hear are cries of “Cut! Cut! But don’t cut my program!”
