Miami Installs Free Public Sunscreen Dispensers In Fight Against Cancer
HughPickens.com writes: If you walk along South Beach in Miami right now, you will notice something strange, even by Florida standards: Dotting the sandscapes are sky-blue boxes that supply free sunscreen. In a novel experiment this year, the City of Miami Beach has put 50 free sunscreen dispensers in public spaces, and those dispensers are full of radiation-mitigating goo, free to any and all passersby. BBC reports that one in five people living in Florida will eventually suffer from skin cancer but the new campaign hopes that increasing people's awareness will lead to a change in behavior. "[The sunscreen dispensers'] visibility — even without additional messaging — could be a good cue to action," says Dr Richard De Visser, a psychologist who has researched health campaigns.
The sunscreen is the type that is effective at preventing cancer and premature skin aging: Broad-spectrum, water resistant, and SPF 30. You can buy a product that is labeled as higher than SPF 30, but it's almost always a waste, and potentially harmful. Above SPF 30, the difference is essentially meaningless. SPF 15 filters out about 93 percent of UV-B rays, SPF 30 filters out 97 percent, SPF 50 filters out 98 percent, and SPF 100 might get you to 99. The problem, though, is the psychology of the larger number. "We put on the "more powerful" sunscreens and then suddenly think we're Batman or some other superhero who can stay out in the sun indefinitely." says James Hamblin. "But no sunscreen is meant to facilitate prolonged exposure of bare skin to direct sunlight." Dr. Jose Lutzky, head of the melanoma program out Mount Sinai, says Florida is second behind California in incidence of melanoma but the trend is going in the wrong direction. "Unfortunately, our numbers are growing. That is really something we do not want to be first in."

Well, that and people with paler complexions are at a greater risk of sunburn and skin cancer (which is why they have to wear higher SPF).
Northern Europe isn't quite as sunny as much of North America. Put simply, white people aren't really evolved for the Florida climate.

Sorry, if it looks like a quack and sounds like a quack, he probably is a quack.
No, but it ignores a 20 year study that shows sunscreen gives no statistical reduction in skin cancer rates.
