Climate change is contributing to depletion of ozone layer?

http://www.msc.ec.gc.ca/topics/uv/summer_forecast_2006_e.html

UV levels are expected to be about 4% higher than pre-1980 levels this summer, due to the ongoing thinning of the ozone layer, according to Environment Canada scientists.

The ozone layer, in the upper atmosphere, continues to show some depletion over Canada. During the past winter, the ozone layer thinned, on average, by about 5%, worsening to 7% below normal in early spring. This depletion is expected to continue throughout the summer, at slightly reduced levels. These values are compared to the normal thickness of the ozone layer, before 1980, when ozone depletion was first recorded.

Exposure to UV rays from the sun increases the risk of sunburn, skin cancers and cataracts and could weaken the immune system. The increased UV levels expected this summer would add to these risks.

Environment Canada scientists created the UV index in 1992, and it is now used around the world to safeguard people from overexposure to the sun.

Despite a significant decline in the use of ozone-depleting chemicals, ozone loss continues and is particularly severe annually over the Antarctic and in some years over the Arctic. Scientists are concerned that climate change may now be contributing to the depletion of the ozone layer.

The UV index is included in Environment Canada's daily weather forecast whenever values are expected to be greater than 3. Use the UV Index forecast as a guide and take precautions when exposed to the sun.

My girls' babysitter won't put sunblock on her sons because she believes that sunblock is more likely to cause cancer than the sun. :(

It always strikes me as amusing that people totally disregard what educated scientists say in favour of their own ideas.

Oh, and I trust you insisted she put sunblock on your daughter.

how sad.

I wear sunblock every single stupid day, because my skin is so fair. My girls don't go out without SPF 30 or more if we are going to play outside.

I told them that we were protecting our skin from UV rays, and that grandma is so wrinkled because she didn't LOL

which leads them to say "my sunblock makes me pretty, and melanoma free" I don't know for sure that the 2 year old understands what melanoma is, but she knows she doesn't want it. LOL

Maybe we won't have to worry about global warming if we continue to deplete the ozone layer?

We just can't get a break, can we?

I don't mean to sound like an evil climate-change skeptic, but what's the evidence for any link here? Usage of various man-made chemicals have also increased, and it seems more likely we're just using something that we haven't realised damages the ozone layer (just like we did with CFCs long ago).

It always strikes me as amusing that people totally disregard what educated scientists say in favour of their own ideas. Well...she IS very religious...

Oh, and I trust you insisted she put sunblock on your daughter.
Absolutely, and she has no problem doing so. Thankfully.

Who knows what the link is? I am just passing on information from Environment Canada:

I am relatively sure that they wouldn't post this material if there was something inhierantly wrong with the info.

We can get a break IF we all do the right thing. What is the right thing? The million dollar question.

We do send an awful lot of pollutants up into the air. :(

Well...she IS very religious...
Well I'd be even more worried if God told her that sunblock causes cancer. As much because God would probably have something better to say as anything.

Absolutely, and she has no problem doing so. Thankfully.
Ah goody. Sunburn is never good. Nor is skin cancer.

I don't really bother with sunscreen unless I’m sunbathing and I never have any problems in fact reminds me of being on holiday with my ex (:( ) she covered herself in sun cream yet still got burns and there’s me with no protection perfectly fine laughing my sweet ass off

*Franberry applies sunblock*

Count yourself lucky. I get sunburned far too often. When I was on holidays in Spain I managed to get sunburned behind my knees. That made wearing shorts very annoying.

This will tell you some things:

I'm pretty sure all the information is from NASA.

There's a possibility i've posted about this before, but i think it deserves a *bump*
