> You keep attaching a lot of Pubmed links, but frankly, in this case at least, they aren't all that compelling and don't even begin to approach a scientific consensus.

Which of these statements do you find controversial?

1) Skin cancer rates are rising dramatically

2) Until very recently (in the last ten years) the vast majority of sunblock was transparent to UVA but opaque to UVB

3) Blocking UVB prevents the skins normal darkening and thickening response as well as sunburn

4) UVA penetrates the skin deeper than UVB and causes damage to the DNA in the cells there

5) Damage to the DNA of skin cells is associated with skin cancer

6) Without sunburn to warn people their skin is damaged they are more likely to leave their skin exposed to the sun.
