Firestorm over arsenic microbe continues to grow
Firestorm over arsenic microbe continues to grow. Now the leader author of the paper responds to the criticisms from other scientists that have been popping up on the web.
Japan’s Venus probe fails to enter orbit
Sad news: It appears that Japan’s Venus probe failed to enter orbit, and might have flown past Venus.
Update: It is confirmed that the spacecraft flew past Venus. There is a chance Japan could try again, when Akatsuka returns to Venus — in about seven years.
The Crab Nebula burps!
The November sunspot graph – still low and below expectations
NOAA’s Space Weather Prediction Center today published its monthly update of the Sun’s developing sunspot cycle (see below). The graph shows the slow rise in sunspots (blue/black lines) in comparison with the consensis prediction made by the solar science community in May 2009 (red line).
As I noted last month, the rise in sunspots as we ramp up to the next solar maximum has definitely slowed, which indicates clearly that we are heading towards the weakest solar maximum in more than two centuries. And as I have noted repeatedly on this website as well as on the John Batchelor Show, that means very cold weather!
Climate models used by IPCC fail to predict past climate patterns
A recent paper published in Hydrological Sciences Journal states that climate models used by IPCC cannot even predict known past climate patterns. Key quote:
It is claimed that GCMs [General Climate Models] provide credible quantitative estimates of future climate change, particularly at continental scales and above. Examining the local performance of the models at 55 points, we found that local projections do not correlate well with observed measurements. Furthermore, we found that the correlation at a large spatial scale, i.e. the contiguous USA, is worse than at the local scale. However, we think that the most important question is not whether GCMs can produce credible estimates of future climate, but whether climate is at all predictable in deterministic terms.
Orbital status of Akatsuki at Venus uncertain
The status of the Japanese probe Akatsuki in its attempt to go into orbit around Venus remains uncertain. The engines fired as scheduled, but radio signal was not regained at the scheduled time. Engineers are analyzing the spacecraft’s position now to see if it was successfully inserted into orbit.
NASA’s arsenic biology discovery slammed
The uncertainty of science! A microbiologist is slamming last week’s NASA discovery that claimed a microbe had incorporated arsenic instead of phosphorus as part of its DNA. Key quote:
In an interview Monday, Redfield said the methods used by the researchers were so crude that any arsenic they detected was likely from contamination. There is no indication that the researchers purified the DNA to remove arsenic that might have been sticking to the outside of the DNA or the gel the DNA was embedded in, she added. Normally, purifying the DNA is a standard step, Redfield said: “It’s a kit, it costs $2, it takes 10 minutes.” She also questioned why the researchers analyzed the DNA while it was still in the gel, making the results more difficult to interpret: “No molecular biologist would ever do that.”
What We Can Learn from 120 Years of Climate Catastrophe Reporting
What can we learn from 120 years of climate catastrophe reporting? We are all gonna die! Or to put it more clearly:
1: The mainstream media outlets are going to publish whatever sells. If someone publishes a story about the world getting colder and people buy it, you can be sure there will be many more stories touting the same headline.
2: There is a long lag between what nature is doing and what the media will report. The lag seems to be anywhere from 10 to 15 years after the climate changes. There is an inertia problem with the mainstream media even when the evidence is clear.
3: When all the stories are about warming or cooling, you can be sure they are all wrong.
When government agencies or United Nations Climate Change conferences warn you that the climate is changing you can be sure that is true — the climate is always changing. Determining the direction is the hard part. Based on the past reporting of these changes, be it from global cooling or warming, the trend will have reversed many years earlier than reported.
Incidentally there has been no global warming for a decade. Get a good grip on your long johns. Maybe a trip to Cancun is not such a bad idea after all, but I’ll wait until the delegates have gone home.
Al Gore’s climate group shrinking
What does this tell us? Al Gore’s climate group has significantly scaled back its field operations.
‘Akatsuki’ probe set to try and enter Venus’s orbit
The Japanese spacecraft, Akatsuki, is set to enter orbit around Venus tomorrow.
For the past 15 years, global warming has stopped
They ain’t gonna like this in Cancun: For the past 15 years, global warming has stopped.

Tinkering with the atmosphere to prevent climate change gains ground in Cancun
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.
Yellowstone caldara rise has slowed
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.
‘A million climate change deaths each year’
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.
New Biggest Volcano in the Solar System?
Snowbound England
Images of a snowbound England.
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.
Build a warning system for asteroids
Astronomers are proposing that an early-warning system be built to warn us a week in advance should an asteroid be heading our way.
