Meanwhile, keep watching for shortage reports, because we should start seeing some sneak in this week, if our doom-o-meter is calibrated correctly.

It seems that every day on the weather network they are warning you about "high" or "very high" levels of UV intensity, and to make sure you use sunblock and wear hats etc. Has it ever been a "low rating", and if people did all the damage, how long is it before the UV ratings are off the chart? And if its a fast crash, where do you get the lotions? Looks like it will be all day in the shade, lol.

Check out the material on this site, in particular this page:

http://www.theozonehole.com/europeanozone.htm


Upper atmospheric conditions in The Northern Hemisphere are becoming similar to those of the Antarctic. The result of this could be the formation of an "Arctic Ozone Hole" or more correctly termed "low ozone event".

The alarming difference is that there are millions of people that live in the area that will be exposed to this deadly radiation. These conditions could expose large numbers of people and animals to more ultraviolet radiation, which can cause skin cancer and disrupt reproduction of some animals and destroy plant life.

The ozone layer, high up in the atmosphere, shields Earth from much of the sun's harmful ultraviolet rays. A gradual thinning due to emissions of damaging man-made chemicals has increased the occurrence of skin cancer and other illnesses related to over-exposure to ultraviolet rays, scientists say.

The continual decline in ozone levels due to chemical depletion and the increase in frequency of mini ozone holes over Europe is resulting in an increase in harmful biologically active UV radiation

One little known fact is the testing of nuclear devices totally eliminates any ozone for a 500 mile radius within ground zeroe for Months to years, and it slowly returns over several years, this was one reason they stopped above ground testing.

The surface area of a sphere is 4piRsquared if I remember right. (Tell me if it is wrong, its been 30 years since college.)

given 8000 radius then we 800 million square miles of ozone.

and one nuke eliminates 750 thousand square miles of ozone for 5 years. pi R squared is area

how many nukes explosion will leave us naked?

As if we are living in space?

answer 4000 nukes will totally remove 100% of all the ozone all around the earth.

It is estimated when the full exchange (Limited exchange is not possible)
happens they will use about 30,000 nukes...

that is 8 times as many nues as needed to toally denude the earth of all ozone.

So what the radiation doesn't kill in a few months in animal life, the ozoneless shielded earth will wipe out all plant life exposed to direct sunshine in a few weeks when the couds clear.

Have a nice day.

I don't think I'll be fussing about what factor sunscreen to use if that happens ...
