Of course, the left will ignore the hard science and embrace the “blame US industry” and “blame Bush” for not signing up for the flawed Kyoto Accord.

Unusually high solar “X-flare” activity may explain the unusually intense 2005 hurricane season. The numbers and intensity of the flares since the last solar maximum have relentlessly bombarded the Earth with high-energy particles and magnetic flux. The effect of these flares includes a high number of hurricanes, and lightning in the eyewalls of the most intense storms.

First, the cause:

NASA – Solar Minimum Explodes

[On September 7, 2005] a huge sunspot rounded the sun’s eastern limb. As soon as it appeared, it exploded, producing one of the brightest x-ray solar flares of the Space Age. In the days that followed, the growing spot exploded eight more times. Each powerful “X-flare” caused a shortwave radio blackout on Earth and pumped new energy into a radiation storm around our planet. The blasts hurled magnetic clouds toward Earth, and when they hit, on Sept 10th and 11th, ruby-red auroras were seen as far south as Arizona. (Photo: the skies above Payson AZ on Sept. 11, 2005.

“That’s a lot of activity,” says solar physicist David Hathaway of the National Space Science and Technology Center in Huntsville, Alabama.

Compare 2005 to the most recent Solar Max: “In the year 2000,” he recalls, “there were 3 severe geomagnetic storms and 17 X-flares.” 2005 registers about the same in both categories. Solar minimum is looking strangely like Solar Max.

One unusual effect:

NASA – Electric Hurricanes

January 9, 2006: The boom of thunder and crackle of lightning generally mean one thing: a storm is coming. Curiously, though, the biggest storms of all, hurricanes, are notoriously lacking in lightning. Hurricanes blow, they rain, they flood, but seldom do they crackle.

Surprise: During the record-setting hurricane season of 2005 three of the most powerful storms–Rita, Katrina, and Emily–did have lightning, lots of it. And researchers would like to know why.

Lightning has been seen in hurricanes before. During a field campaign in 1998 called CAMEX-3, scientists detected lightning in the eye of hurricane Georges as it plowed over the Caribbean island of Hispaniola. The lightning probably was due to air forced upward — called “orographic forcing” — when the hurricane hit the mountains.

“Hurricanes are most likely to produce lightning when they’re making landfall,” says Blakeslee. But there were no mountains beneath the “electric hurricanes” of 2005—only flat water.
