Sunspots 197


Things I have recently spotted that may be of interest to someone else:



Science:
Hummer drivers are much more likely to get a ticket, says Wired.

Music:
Slate on temperature and stringed instruments (such as the ones Itzhak Perlman and Yo-Yo Ma played, but which weren't actually broadcasted at President Obama's inauguration).

An article in Christianity Today, by a man who has been in such bands quite a bit, proclaiming that church worship bands are (among other things) usually too loud.

Computing:
Dilbert on on-line identity ethics.

OpenOffice 3.0.1, a free alternative to Microsoft Office, is now available.

Christianity:
He Lives writes on the "great mystery of liberal Christianity." By liberal Christianity, he means a so-called Christianity that rejects the miracles of the New Testament, including the virgin birth and the resurrection. So what is that mystery? The mystery is why anyone would want to crucify Jesus, if He was just a mostly mild-mannered teacher.

I don't find it a mystery that people can come to the conclusion that Jesus was just a mild-mannered teacher, though I disagree.

The mystery to me is why such people would want the title "Christian." Surely there is a better way to describe their spirituality!

Thanks, Henry Neufeld. As usual, well put.

Keeping in mind that windmills are hazardous to birds, be wary of the unintended consequences of believing and contributing to the all-knowing environmental lobby groups.
Climate and economy are being linked. Climate is a multiple loop, multiple input, complex system. The facts and the hypotheses do not support CO2 as a serious 'pollutant'. In fact it is plant fertilizer and seriously important to all life on the planet. It is the red herring used by the left to unwind our economy. That makes the science relevant.
Water vapour (0.4% overall by volume in air, but 1 – 4 % near the surface) is the most effective green house gas followed by methane (0.0001745%). The third ranking greenhouse gas is CO2 (0.0383%), and it does not correlate well with global warming or cooling either; in fact, CO2 in the atmosphere trails warming which is clear natural evidence for its well-studied inverse solubility in water: CO2 dissolves in cold water and bubbles out of warm water. The equilibrium in seawater is very high; making seawater a great 'sink'; CO2 is 34 times more soluble in water than air is soluble in water.
CO2 has been rising and Earth has been warming. But the correlation trails. Correlation is not causation to be sure. The causation is being studied, however, and while the radiation from the sun varies only in the fourth decimal place, the magnetism is awesome.
“Using a box of air in a Copenhagen lab, physicists traced the growth of clusters of molecules of the kind that build cloud condensation nuclei. These are specks of sulphuric acid on which cloud droplets form. High-energy particles driven through the laboratory ceiling by exploded stars far away in the Galaxy - the cosmic rays - liberate electrons in the air, which help the molecular clusters to form much faster than climate scientists have modeled in the atmosphere. That may explain the link between cosmic rays, cloudiness and climate change.”
As I understand it, the hypothesis of the Danish National Space Center goes as follows:
Quiet sun → reduced magnetic and thermal flux = reduced solar wind → geomagnetic shield drops → galactic cosmic ray flux → more low-level clouds and more snow → more albedo effect (more heat reflected) → colder climate
Active sun → enhanced magnetic and thermal flux = solar wind → geomagnetic shield response → less low-level clouds → less albedo (less heat reflected) → warmer climate
That is how the bulk of climate change might work, coupled with (modulated by) sunspot peak frequency there are cycles of global warming and cooling like waves in the ocean. When the waves are closely spaced, the planets warm; when the waves are spaced farther apart, the planets cool.
The ultimate cause of the solar magnetic cycle may be cyclicity in the Sun-Jupiter centre of gravity. We await more on that.
Although the post 60s warming period appears to be over, it has allowed the principal green house gas, water vapour, to kick in with more humidity, clouds, rain and snow depending on where you live to provide the negative feedback that scientists use to explain the existence of complex life on Earth for 550 million years. Ancient sedimentary rocks and paleontological evidence indicate the planet has had abundant liquid water over the entire span. The planet heats and cools naturally and our gasses are the thermostat.

Thank you, sort of, Anonymous, whoever you may be.

I was going to delete your comment as being irrelevant to the post, but I guess that the comment may have something to do with the title (which I have used every week for nearly four years) so I'll leave it.
