Some scientists think the “warming trend” which (despite the fact that we’re having our usual early-June heatwaves) has stalled out over the past few years was helped along by sunspots. And lately, there aren’t any.
The scientists said periods of inactivity are normal for the sun, but this period has gone on longer than usual.
“It continues to be dead,” said Saku Tsuneta with the National Astronomical Observatory of Japan, program manager for the Hinode solar mission. “That’s a small concern, a very small concern.”
Not sure what there is to be “concerned” about. It’s not like we can do anything about it. Either old Sol will spot and flare or he won’t.
Dana Longcope, a solar physicist at MSU, said the sun usually operates on an 11-year cycle with maximum activity occurring in the middle of the cycle. Minimum activity generally occurs as the cycles change. Solar activity refers to phenomena like sunspots, solar flares and solar eruptions. Together, they create the weather than can disrupt satellites in space and technology on earth.
The last cycle reached its peak in 2001 and is believed to be just ending now, Longcope said. The next cycle is just beginning and is expected to reach its peak sometime around 2012. Today’s sun, however, is as inactive as it was two years ago, and scientists aren’t sure why.
“It’s a dead face,” Tsuneta said of the sun’s appearance.
Tsuneta said solar physicists aren’t like weather forecasters; They can’t predict the future. They do have the ability to observe, however, and they have observed a longer-than-normal period of solar inactivity. In the past, they observed that the sun once went 50 years without producing sunspots. That period, from approximately 1650 to 1700, occurred during the middle of a little ice age on Earth that lasted from as early as the mid-15th century to as late as the mid-19th century.
The founder of The Weather Channel pipes up:
I suspect you haven’t heard it because the mass media did not report it, but I am not alone on the no man-made warming side of this issue. On May 20th, a list of the names of over thirty-one thousand scientists who refute global warming was released. Thirty-one thousand of which 9,000 are Ph.ds. Think about that. Thirty-one thousand. That dwarfs the supposed 2,500 scientists on the UN panel. In the past year, five hundred of scientists have issued public statements challenging global warming. A few more join the chorus every week. There are about 100 defectors from the UN IPCC.
