Wait a minute, you claimed that the trend was normal.
Please supply cites to support your claim.

If it is caused by CFC's, then it makes no difference
whether or not it is still getting 6.8% worse per decade.
We need to put it back the way it was.

It is measured by NASA's satellite, and it radiates
down on earth from above.  Everything under hole and
and in the sun gets additional UV radiation.

Risk factors associated with melanoma skin cancer are
a history of severe sunburn.  Risk factors for squamous
and basal cell carcinomas include chronic exposure to
the sun.

Why is skin cancer an important public health problem? 

Skin cancer is the most common and most rapidly increasing form
of cancer in the United States. An estimated one million new
cases of skin cancers occur each year. The most serious form of
skin cancer, melanoma, will account for about 38,300 new cases in
1996, and will claim 7,300 lives. Skin cancer, if detected early,
has an excellent chance of cure. According to a recent survey by
the American Academy of Dermatology, most Americans do not know
what melanoma skin cancer is, and are not aware of the risk
factors associated with the disease. 

Risk factors associated with melanoma skin cancer are a history
of severe sunburn, particularly when it occurs early in life;
light skin color; a family history of melanoma; a personal
history of melanoma; and the presence of moles and freckles. Risk
factors for squamous and basal cell carcinomas include chronic
exposure to the sun, family history of skin cancer, personal
history of skin cancer, and light color skin. 

What recommendations do health professionals provide to reduce
the occurrence of skin cancer? 

The occurrence of skin cancers and death associated with skin
cancer can be reduced by changing behaviors associated with sun
exposure. Educational programs for both adults and children are
important; parents and caregivers may be particularly receptive
to educational messages that aim to protect children from
excessive sun exposure. No scientific evidence currently exists
to support mass screening for skin cancer. Although skin
self-examination is not scientifically proven as effective, it is
prudent for persons at high risk. Any individual with a
suspicious or changing mole or other growing or unusual skin
lesion should be examined by a physician. 

What are the important educational messages regarding sun exposure? 

Health messages should suggest wearing a broad brimmed hat and
protective clothing when outdoors; seeking shade; staying indoors
when the sun is most intense - whenever possible, usually between
the hours of 10 am and 4 pm; and wearing a broad-spectrum sun
screen of SPF 15 or greater. 

What role is the Centers for Disease Control and Prevention (CDC)
playing in skin cancer prevention activities? 

Since 1994, CDC has developed partnerships and conducted
activities supporting the growth of CDC's National Skin Cancer
Prevention Education Program. The Program's aim is to increase
public awareness about skin cancer and to help the nation achieve
skin cancer prevention objectives established by Healthy People
2000. Elements of this program include developing and
disseminating of educational messages that target children and
their parents or other caregivers; developing school education
curricula guidelines; evaluating the utility and value of the
Ultraviolet (UV) Index; and developing educational messages for
the health care provider. 

CDC will join with the American Academy of Dermatology to issue a
national call to action to enhance skin cancer prevention
awareness during May National Melanoma/Skin Cancer Detection and
Prevention Month and to strengthen efforts to prevent skin
cancer.
