First, I believe the UV radiation is present on my skin on hot cloudless days even though the rays are absorbed by the atmosphere. I recognise by far most of the sun%26#039;s natural rays are filtered out, but to me reducing the attenuated radiation still makes a difference.
Secondly, I believe a thin chemical barrier has a significant effect on electromagnetic radiation. I use around 10 ml of 15% active solution, around 1.5 g for my 100 Kg body or 15 ppm. When applied it gives a layer so thin I cannot see it - something like 100th part of a millimeter. Compared to the atmosphere the rays first pass through it is truly negligible - yet I believe this tiny layer works in blocking what kilometers of air let pass.

Finally, I believe I am protecting myself against skin cancer. Studies linking the two are based on scientific studies and statistics and no-one can definitely link a single case to UV exposure. Yet I use sun screen because I do not want to risk my health.I know skeptics see the world differently - do you use sunscreen?

I ask the question because skeptics seem to think a few more ppm of CO2 in the atmosphere could not possibly block heat escaping as electromagnetic radiation - yet accept an invisible layer of sunscreen completely blocks other radiation. They also do not question the validity of the link between the natural rays of the sun and the emergence of skin cancer - although the scientific link between the two is probably no stronger than the link between greenhouse gases and global warming. Most think I am sensible in taking the precaution - even though sunscreens are really quite expensive.

I use it because it works. It is quite amazing that such a thin layer can block so much UV - but that%26#039;s obviously what it%26#039;s doing.
This does seem like an odd question though. Why wouldn%26#039;t skeptics of AGW use sunscreen? The evidence that sunscreen works is readily available. 0% 0 Votes -
Of course, sunscreen products have been around for well over 40 years. What%26#039;s changed - nothing! Will we continue to use suncreen products - of course. We got it right along time ago. Nothing has changed except the language.

Using sun screen is cheap. Reducing co2 emissions by 70-80% (or even 50%) that the greenies want us to do, is not.

Of course I do, because I know, from personal experience, that without sunscreen, I may burn.

UV is %26quot;present on your skin%26quot; even on cloudy days.

Are you trying to make a point here? Sunscreen was made specifically to block UV, nothing else. Most of the atmosphere does not react with UV rays.

-I accept that sunscreen blocks UV radiation from personal experience.
-Heat and infrared radiation are not the same thing. People really need to understand this.

I do not know who this is. I have never met, seen, heard of, or spoke to a skeptic or %26quot;denialist%26quot; who think this way. 20% 1 Vote
