The sun found to vary in unexpected ways

11:06 am

Recent monitoring of the Sun’s brightness as it went from maximum to minimum in its solar cycle has found that, surprisingly, the changes in brightness across different wavelengths do not necessarily vary in lockstep. Key quote:

SIM suggests that ultraviolet irradiance fell far more than expected between 2004 and 2007 — by ten times as much as the total irradiance did — while irradiance in certain visible and infrared wavelengths surprisingly increased, even as solar activity wound down overall. The steep decrease in the ultraviolet, coupled with the increase in the visible and infrared, does even out to about the same total irradiance change as measured by the TIM during that period, according to the SIM measurements.

The stratosphere absorbs most of the shorter wavelengths of ultraviolet light, but some of the longest ultraviolet rays (UV-A), as well as much of the visible and infrared portions of the spectrum, directly heat Earth’s lower atmosphere and can have a significant impact on the climate.

pilot exposes airport security flaws, gets threatened by TSA

10:09 am

A pilot videotapes what he thinks are serious airport security flaws and immediately gets threatened by the TSA for doing it. Key quote:

Three days after the pilot posted his airport security tour on YouTube, four federal air marshals and two sheriff’s deputies arrived at the pilot’s house, which he also recorded. They were there to confiscate his federally-issued handgun. A letter later arrived saying, “An FFDO [Federal Flight Deck Officer] must not engage in… conduct that impairs the efficiency of TSA… or causes the loss of public confidence in TSA…”

The pilot’s attorney believes the feds sent six people to the pilot’s house to send a message. “And the message was you’ve angered us by telling the truth and by showing America that there are major security problems despite the fact that we’ve spent billions of dollars allegedly to improve airline safety,” says Don Werno, the airline pilot’s attorney.

How Obamacare is Hastening the bankruptcy of state governments

3:50 pm

Repeal the damn bill! How Obamacare is hastening the bankruptcy of state governments. Key quote:

If state Medicaid spending increases by 41 percent as projected by [the Centers for Medicare and Medicaid Services], then by next year Medicaid could end up consuming nearly 30 percent of the average state budget. Medicaid would greatly exceed all other state priorities, including education, which tops state budgets at about 22 percent. In fact, state spending on education would experience certain cuts next year. [emphasis mine]
