The Japanese spacecraft, Akatsuki, is set to enter orbit around Venus tomorrow.
They ain’t gonna like this in Cancun: For the past 15 years, global warming has stopped.
What could possibly go wrong? The environmental global warming activists at the Cancun climate summit appear increasingly eager to encourage governments to tinker with the atmosphere to prevent climate change. The most frightening quote:
Funding may not be far off.
In September, the U.S. Government Accountability Office recommended in a 70-page report that the White House “establish a clear strategy for geoengineering research” within its science office. A month later, a report from U.S. Rep. Bart Gordon, a Democrat from Georgia who chairs the House Science and Technology Committee, urged the government to consider climate-engineering research “as soon as possible in order to ensure scientific preparedness for future climate events.”
The U.S. panel had collaborated in its study with a British House of Commons committee. “We may need geoengineering as a `Plan B,'” the British report said, if nations fail to forge agreement on a binding treaty to rein in greenhouse gases.
Perhaps most significantly, the U.N.-sponsored Intergovernmental Panel on Climate Change, IPCC, the global authority on climate science, agreed in October to take on geoengineering in its next assessment report. Its hundreds of scientists will begin with a session next spring.
In a paper published today in Geophysical Research Letters of the American Geophysical Union, scientists note that the rise of giant volcanic caldara under Yellowstone National Park has slowed significantly since 2006 and since 2008 has actually subsided somewhat. Key quote from the paper:
Here we propose that as the caldera source continues inflating, the accumulated strain energy in the deformed crust could promote earthquakes with mechanisms such as hydrofracturing,, migration of magmatic fluids, and brittle fracturing of rocks. These events can subsequently depressurize the magmatic systems or release the accumulated strain energy, slowing the uplift or even influencing a change in motion to subsidence. In January 2010 the Yellowstone caldera experienced another large earthquake swarm at its northwestern boundary close to the location of the 1985 swarm. . . . In the following five months the caldera experienced the first overall subsidence since the inception of its uplift in 2004. This scenario is similar to that in 1985 where a reverse of caldera uplift to subsidence was temporally correlated with the largest observed Yellowstone earthquake swarm.
Global warming activists today released a report claiming there will be “a million climate change deaths each year” by 2030.
Wanna bet? This article from AFP is typical of what I call press release journalism. The unnamed author shows no skepticism, and simply regurgitates what these activists told him without question. I for one would love to see this so-called report, as I suspect it has more scientific holes than a hunk of swiss cheese.
Update: I just did a quick scan of this so-called “peer-reviewed” report, and it is a piece of junk. (You can see the report’s press release here. The report can be downloaded here [pdf]) Its data is compiled from UN political workshops, not scientific research. Moreover, it uses the 2007 IPCC report as its fundamental source, even quoting some of that report’s now discredited research, such as its claim that the glaciers in the Himalayas will be gone in mere decades.

I know it’s weather and not climate, but Europe is experiencing its second cold winter in a row, despite predictions by many in the global warming community that such things would never happen again. My point here is that their claims in the late 1990s that hot streaks and big storms were proof of global warming were patently dishonest, and it is worthwhile to remind ourselves of this fact.
Astronomers are proposing that an early-warning system be built to warn us a week in advance should an asteroid be heading our way.
And damn, do I want to rappel into them!
This week’s release of images from the HiRISE camera on Mars Reconnaissance Orbiter included these spectacular photos of two deep pits, approximately 180 and 310 meters in diameter and located aligned with a series of depressions that suggest additional passages at their base.
The first image shows the pits in the context of the surrounding terrain. From the caption:
These pits are aligned with what appears to be larger, degraded depressions. The wispy deposit may consist of dark material that has been either blown out of the pits or from some other source and scattered about by the local winds.
The next two images are heavily processed close-ups of each pit in order to bring out the detail within. From the caption:
The eastern most and smaller of the two pits contains boulders and sediment along its walls and brighter aeolian dune sediments on its floor. The larger, western most pit contains sediment and boulders with faint dune-like patterns visible on the deepest part of the floor. Both pits have steep eastern walls and more gently sloped western walls that transition gradually into the pit floor. Steep resistant ledges containing boulders that overhang and obscure the pit floors form the eastern walls.
A commenter to one of my other posts, ZZMike, asked this question today: ” What is NASA’s Secret Astrobiology Announcement?” and quoted this from another website, “Science fans across the Internet are eagerly awaiting an announcement from NASA’s astrobiology team. All NASA will say about the press conference is that it will “discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life.”
Unfortunately, Mike, this great discovery is not the big news that everyone is hoping for, such as the discovery of life on Mars. Instead, it is about the discovery that a certain microbe can eat and digest arsenic, using it as one of the six vital basic components of life (carbon, hydrogen, nitrogen, oxygen, sulfur, phosphorus) in place of phosphorus. This is very significant since it tells us that alien life could very well be far more alien than previously imagined.
What makes this story interesting, however, is not the discovery itself (which is important). Instead, because NASA was so vague in its press announcement it allowed a large number of irresponsible reporters and bloggers to go nuts trying to guess what the story was about. When these rumors began to get out of control, the magazine Science finally sent out a notice to journalists noting the specific paper and discovery so that they at least would know in advance what the conference was about.
As Mike above as well as several other people noted to me in emails, I had written nothing about this story on behindtheblack. This was intentional. Without knowing what the conference was about, I wasn’t going to speculate about it. Once I knew, I still remained silent because the story was under embargo by Science and I respect these embargos. Now that the embargo has been lifted, I can speak.
What I want to speak about is the danger of speculation, especially among journalists. This is a serious problem today. Too often journalists speculate off the cuff, without knowing a goddamn thing about the subject, And all too often, they are downright wrong, and help contribute to misinforming the public. The result: the field of journalism has a terrible reputation with the public. No one trusts what journalists tell us. Worse, this lack of trust is helping fuel the ignorance and anger that seems to be rising in society, as no one knows what to believe about some of the most important issues of our time.
Journalists need to stop doing this. Rather than fantasize what they don’t know, journalists need to focus on what they do know. If they do that, they will significantly help repair the sagging reputation of their field.

There are more stars in heaven and earth than have been dreamt of by scientists, three times more it turns out. And they are all dwarves!
Apropos of the desire of IPCC chief Rajendra Pachauri to re-engineer the climate to battle global warming, including spraying “sulphate particles high in the atmosphere to scatter the sun’s rays back into space,” planetary scientists have pinpointed the source of Venus’s sulphuric acid clouds, and from this believe that the IPCC scheme might backfire badly, doing more harm than good.
Cassini pinpoints the hot spots in the cracks on Enceladus.
What could go wrong? Railroad engineer and head of the IPCC Rajendra Pachauri announced at the Cancun climate summit today that he has decided that the threat of global warming is so great that the IPCC is going to recommend in its next report (AR5) that actions be taken to re-engineer the climate. Key quote:
“The AR5 has been expanded and will in future focus on subjects like clouds and aerosols, geo-engineering and sustainability issues,” [Pachauri] said.
Later this year IPCC “expert groups” will meet in Peru to discuss geo-engineering. Options include putting mirrors in space to reflect sunlight or covering Greenland in a massive blanket so it does not melt. Sprinkling iron filings in the ocean “fertilises” algae so that it sucks up CO2 and “seeding clouds” means that less sunlight can get in. Other options include artificial “trees” that suck carbon dioxide out of the air, painting roofs white to reflect sunlight and man-made volcanoes that spray sulphate particles high in the atmosphere to scatter the sun’s rays back into space.

The image below from Mars Reconnaissance Orbiter shows gullies remarkably similar to gullies formed on Earth by flowing water, thus providing striking evidence that at some time in the past liquid water did flow on the Martian surface, something that is not possible now. Key quote from the caption:
The gullies shown in the subimage (approximately 710 x 1100 yards) have well developed alcoves, deeply incised channels, and large depositional fans, and are similar to terrestrial landscapes sculpted by surficial water.
The gullies shown in the subimage experienced several periods of activity, as evidenced by older channels cut by younger ones or by their deposits. The current and recent Martian temperatures and atmospheric conditions would not allow for water to be stable at the surface for extended periods of time: it is so cold that the water would freeze, and then it would sublime quickly, because the air is very thin and dry. These gullies could have formed under a different climate, or maybe by repeated bursts of transient fluids. Current leading hypotheses explaining the origin of gullies includes erosion from seepage or eruption of water from a subsurface aquifer, melting of ground ice, or dust-blanketed surface snow.
The hurricane season is about to end, and though it appears that the predictions for this season were just about right, no hurricanes touched down in North America for the second year in a row. Key quote:
“There was only a 2% or 3% chance of getting this many hurricanes and not having one hit the U.S.”

Link fixed. Sorry!
Saturn moon has a thin oxygen and carbon dioxide atmosphere. Key quote:
“The major implication of this finding at Rhea is that oxygen atmospheres at icy moons, until now only detected at Europa and Ganymede, may in fact be commonplace around those irradiated icy moons throughout the universe with sufficient mass to hold an atmosphere,” said study leader Ben Teolis of the Southwest Research Institute in San Antonio, Texas.
Better stop using that SUV! Global warming will not only destroy the Earth, a food scientist now claims that it will also destroy your Thanksgiving dinner!
Pasty, dry turkey meat along with expensive fruits, vegetables and potatoes could be on the horizon if more variable extremes in regional weather patterns continue as a likely result of climate change, indicates author Neville Gregory.
