Sunspot Activity Continues To Drop
slreboy writes "The sunspot cycle is behaving a little like the stock market. Just when you think it has hit bottom, it goes even lower. The year 2008 was a bear. There were no sunspots observed on 266 of the year's 366 days (73 percent). To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days. Prompted by these numbers, some observers suggested that the solar cycle had hit bottom in 2008. Maybe not. Sunspot counts for 2009 have dropped even lower. As of March 31st, there were no sunspots on 78 of the year's 90 days (87 percent)..."
The sun rotates. In the course of a month, we see it from all sides.
I would like to point out that this law states:
"If A and B are each in thermal equilibrium with C, A is also in thermal equilibrium with B."

Not only is the summary ripped from the linked article without quoting it, but the article is plagiarized in whole from ScienceDaily! I knew I'd seen it before this article, and this explains why. The blogger even hotlinked the image from science daily, wasting their bandwidth.
The linked article in the summary should be adjusted to the original ScienceDaily article and the entire summary should be quoted from it rather than attributed to slreboy.
I had but a simple dream, to destroy all humans.
I realize that HAM radio is a bit of an anachronism in the eyes of most slashdot readers, but it's still the most viable medium for emergency communications. Unfortunately, with sunspot activity being so low, HF communications become very limited. Whole bands of RF spectrum are almost unusable, because the E-layer of the ionosphere can no longer bounce higher frequencies of radio waves. 40m wavelength and lower tend to still be usable, 20m is come-and-go, and 17m and higher become sporadic or completely unusable.
I'm 31, I've been a HAM for 6 years. My cell phone often doesn't get coverage where I roam, and my power and internet and landline phone have been knocked out by storms and provider mistakes. Radio works when all else fails... ...but sometimes it works better than others!
I think his point was that you should not compare a year's worth of data to 3 months' worth. They could simply take the last 365 days and compare it to the 365 before that and it would make a lot more sense.
The problem, of course, is all the -other- people already using calendar years with their data like it means something.

The article about Jupiter mentions nothing about a planet-wide increase in temperature. The Mars article mentions an increase in dust storm reducing albedo and therefore increasing light absorption. Still a far cry from the ggp's claim that 5 planets are all experiencing the same increase in temperature.
Those who can, do. Those who can't, sue.
ROFL, and how, pray tell, do those articles qualify as "30 years" of temperature data that "correlate with the rising temperature trends on Earth in that period." Oh, wait, they don't.
Hell, the Jupiter article isn't about planetary warming at all. And as for Mars, "Martian climate is primarily driven by dust and albedo and there is little empirical evidence that Mars is showing long term warming." (source).
See how I provided a citation for my quote? And how the article linked contains references for its claims? Neat, eh?
