Maybe. But Al Gore explained this morning that scientists say that global warming has or will result in a ten fold increase in lightning strikes.

I have long noticed the absence of lightening rods on homes here in Hawaii. They would seem cheap and practical on homes with metal roofs.
LIghtening rods (invented by Ben Franklin) are common on the mainland mid-west and east. For some reason, I guess lack of lightening, the pacific states don't require them. After 1,500 lightening started fires in California that might change. That must have been one helluva storm.
Assume the best and ask questions.

We don't have a lightening rod so to speak, however we do have this antenna that was erected nearly 25 years ago to receive radio signals.
I was told the other day that this antenna now serves as a "lightening rod" when I asked why we still have it and don't really need it.[^] It is much higher then the lightening rods I have seen in the mainland. Editx2: My tutulady was shocked through a phone line here in Hawaii because of lightening... no kidding! Ah geez lighten up [  ] [ ]------- Rally For the Plan

I'm not normally a spelling nazi, but after reading this topic I feel like I have to reach out and beg for the massacre to stop!
LIGHTNING That is the only proper spelling of this electrical phenomenon. LIGHTENING is what you do to your hair when you streak it, what happens to the sky when the sun rises, the process of taking all the crap out of your suitcase that you don't really need, having a garage sale, or even how you feel when you take a large crap or give birth to a child. Thank you Carey, AlaskaSteven, Glen, and any one else who is old fashioned. Not to pick on Cindy, only mentioning this because there are a lot more replies about lightening than lightning! [:0] OK, back to the flashing, I thought i was going to LOOSE it ... I mean LOSE it. [ ]

Neither Hawaii nor Alaska is pictured in the mortality map displayed via the link below, but the image of the continental US and text describe the relative hazard by region -including from lightning. Unless perhaps one is a golfer it looks like the odds are fairly low for mortality from lightning strike, especially compared to health-related issues and traffic accidents. According to this study 2,260 people were killed by lightning in the USA between 1970 and 2004 (an average of approximately 66 people per year, nationwide). 'Death map' shows where nature kills most - Americans more likely to be killed by heat, drought than an earthquake by Jeanna Bryner http://www.msnbc.msn.com/id/28268989/?GT1=43001 "Cutter and Borden found that of the natural hazards, some were more deadly than others over the years, including: * Heat/drought (ranked highest among hazards): caused 19.6 percent of total deaths due to natural hazards * Severe summer weather: 18.8 percent * Winter weather: 18.1 percent * Flooding: 14 percent * Tornadoes: 11.6 percent * Lightning : 11.3 percent * Geophysical events (such as earthquakes), wildfires and hurricanes: less than 5 percent * Coastal (storm surge, rip currents and coastal erosion): 2.3 percent "It is the chronic hazards like severe summer weather and severe winter weather and heat that are contributing the majority of the hazard fatalities, not fatalities associated with things like earthquakes or hurricanes," Cutter told LiveScience. She added that people and officials tend to be more prepared for big hurricanes and tornadoes, which could partly explain the lower mortality from these storms compared with everyday occurrences. Overall, during the study period, nearly 20,000 people died due to natural hazards. For comparison, here are the top five causes of U.S. deaths in 2005, according to the Centers for Disease Control and Prevention: * Heart disease: 652,091 deaths * Cancer: 559,312 * Stroke (cerebrovascular diseases): 143,579 * Chronic lower respiratory diseases: 130,933 * Accidents (unintentional injuries): 117,809 " ------------------------------------------------------------- FAIR USE NOTICE: This post may contain copyrighted material.

Fascinating. Awesome photo, too. Lightning helps predict hurricane fury 'Eyewall replacement' phenomenon one of many ways hurricanes intensify.
