What's Wrong with the Sun? Supposedly nothing 11 Jul 08 - The sun is behaving normally, says NASA solar physicist David Hathaway. "There have been some reports lately that Solar Minimum is lasting longer than it should. That's not true. The ongoing lull in sunspot number is well within historic norms for the solar cycle."
This report is newsworthy because of a growing buzz in lay and academic circles that something is wrong with the sun. A careful look at the data, however, suggests otherwise.
"The sun is now near the low point of its 11-year
activity cycle," says Hathaway. "We call this 'Solar Minimum.' It is the
period of quiet that separates one Solar Max from another." Hathaway has studied international sunspot counts stretching all the way back to 1749 and he offers these statistics: "The average period of a solar cycle is 131 months with a standard deviation of 14 months. Decaying solar cycle 23 (the one we are experiencing now) has so far lasted 142 months--well within the first standard deviation and thus not at all abnormal. The last available 13-month smoothed sunspot number was 5.70. This is bigger than 12 of the last 23 solar minimum values."
"The current minimum is not abnormally low or long," says Hathaway, nor is the quiet of 2008 the second coming of the Maunder Minimum. "We have already observed a few sunspots from the next solar cycle," he says. "This suggests the solar cycle is progressing normally."
Hathaway anticipates more spotless days, maybe even hundreds, followed by a return to Solar Max conditions in the years around 2012.
Is Hathaway correct? I don’t know. What I do know is that I’m very concerned.
If we should see “hundreds” more spotless days as Hathaway says, what will that do to the weather in the northern hemisphere this coming winter?

1 Jul 08 - In a news conference held in Orlando, Florida today, Mr. John L. Casey, Director of the Space and Science Research Center, issued a landmark declaration on climate change. “In an opinion echoed by many scientists around the world, the Space and Science Research Center (SSRC), today declares that the world’s climate warming of the past decades has now come to an end. A new climate era has already started that is bringing predominantly colder global temperatures for many years into the future. In some years this new climate will create dangerously cold weather with significant ill-effects world wide. Global warming is over – a new cold climate has begun.” On the subject of cold climate effects on agriculture, Casey was not optimistic. “I can see,” he added, “just like the last time this 206 year cycle brought cold, that there will be substantial damage to the world’s agricultural systems. This time however we will have eight billion mouths to feed during the worst years around 2031 compared to previously when we had only one billion. Yet even then, many died from the combined effects of bitter cold and lack of food.” In his concluding remarks, Casey called on all leaders to immediately move from the past global warming planning to prepare for the already started change to a cold climate.
