Murder for the sake of climate idealogy

5:13 pm

Bumped. Scroll down to see the update.

This video has been making the rounds on the web. Though I warn you that is somewhat graphic, it is essential that you watch it.

When I first saw this about a week ago, I didn’t quite know what to make of it. It was so vile and offensive I could not believe that it was legitimate. It obviously wants to pay some homage to Monty Python, but even Monty Python never went this far. How could anyone possibly think that killing small children in the name of environmentalism was in any way funny? And how could anyone ever believe that this video would persuade anyone to go along with the 1010 environmental campaign? If anything, the video does an excellent job of discrediting this organization and everyone involved with it.

Thus, despite what some bloggers were saying, I held back commenting, just to make sure the video was real and not a terrible prank meant to sabotage.

There is now no reason to hold back. Late last week, the 1010 organization itself issued an apology, admitting that this video was their handiwork. Before I continue, I think it is worthwhile for you to also read their apology, in all its venal glory. In many ways, it condemns them and their allies far more than the video did:

WISE telescope moves into final phase of mission

2:18 pm

Having run out hydrogen coolant for its infrared cameras and with only a few more months of usable life, the Wide-Field Infrared Survey Explorer (WISE) has shifted its work from deep space astronomy to completing its last sweep of the solar system in a search for asteroids and comets.

Update: At a press conference going on right now at the 42nd meeting of the AAS Division for Planetary Sciences, WISE scientists note that the mission extension will continue for one month. If that month is successful, the mission will continue until the end of January 2011 in order to complete its solar system sweep. After this the spacecraft will be put in hibernation, available for future work.

Summary of solar system results so far:

  • 33,576 asteroids discovered of which 120 were Near Earth Asteroids.
  • 19 new comets.

Liquid on Titan

3:32 pm

The Cassini image below, released today at the 42nd meeting of the AAS Division for Planetary Sciences, shows light reflecting off a lake on Titan’s northern hemisphere. According to the scientists who took the image, this is the first definitive confirmation of the presence of liquid in those lakes.

The wind-blown dunes of Mars

1:45 pm

The HiRise Camera on Mars Reconnaissance Orbiter has released some wonderful new pictures, showing what are called barchan dunes on Mars.

Barchans are crescent-shaped, with the horns of the crescents pointing downwind. One barchan is visible in the upper part of the image, with the Southeast (lower right) horns longer than the other. This trend, along with the position of the steep face of the dune on the South side, indicates that the predominant winds which formed the dunes came from the North.

There are a lot more great images on the websites above.

Antarctic increase in sea ice since 1970 cannot be explained by ozone hole

5:37 pm

In another paper published today in the Geophysical Research Letters of the American Geophysical Union, researchers have found, according to their computer model, that the increase in sea ice since 1970 in Antarctica cannot be explained by the ozone hole. (Note that the sea ice has been shrinking in the northern hemisphere while it has been growing in the south.) Key quote from paper:

It is presently unclear why the observed Southern Hemisphere sea ice extent trends are so different from those in the Northern Hemisphere. Previous studies have suggested that the cause might be related to atmospheric circulation changes induced by the stratospheric ozone hole. The results in this study are not consistent with this view and highlight the need for continued investigations of Antarctic sea ice extent trends.

Modern climate models can’t predict sudden climate change

5:03 pm

A paper published today in Geophysical Research Letters of the American Geophysical Union says that the general circulation climate models used by scientists today to predict things like global warming cannot predict past examples of similar sudden climate change. Key quote from abstract:

These [sudden] shifts are thus noise induced with very limited predictability, and early detection of them in the future might be wishful thinking.

Listen to the sound of Babylonia

11:55 pm

A researcher at the University of Cambridge is posting audio recordings on the web of Babylonian poetry, myths, and other texts, so that everyone can hear what the ancient languages sounded like. Key quote:

“In many cases [the works] are the equivalent of Old English tales like Beowulf,” Dr. Worthington added. “Through them, we meet gods, giants, monsters and all sorts of other weird and wonderful creatures. As stories they are amazing fun.”
