Ice Caps Melting and the 250 ppm.

I heard this information (perhaps disinformation) on a local radio station not too long ago.

Apparently, the ozone hole over the arctic is now at 250 ppm (parts per million.) Parts per million of what I am not sure; I assume this to mean ppm of cfc's or some other ozone depleting material.

Apparently, this increases by about 3 or 4 ppm per year, but the rate of increase is also rising.

It is speculated that when the level reachs 500 ppm, the arctic ice cap will melt.

Can anyone here validate this information?

Anyone?

Someone here must have some info.

hi there! I can remember seeing an episode on MSN video called Antarctica Melting from National Geographic. If you go here: video.msn.com... do a search on the word - ozone ...you will find the video.

Also found: www.socialismtoday.org...

Hope this is of some helps...God Bless

A few items in the news of late in regards to the ice sheets (I have read) predominately have been in regards to Greenland that include estimated stats. Surprisingly, this is finally getting some decent mainstream coverage.

Greenland ice sheet melting speedily, making seas rise faster

Thank you for the replies and links.

I am still looking for more information regarding the 250ppm number that I heard. I may have to contact the radio station.

Well from what your describing I assume its talking about the CO2 concentration at the pole. If it did reach 500 it will get rather warm here on earth. Though we humans are putting a lot of stuff in the atmosphere but life on earth has increased along with our industrial revolution the living things on earth make way more CO2 then humans. Though the data collected from vostoc and other ice cores do not match up showing that they are not reliable sources. The real truth is that we do not have the data or the power to look one day in to the future concerning our weather let alone 100 years.

Good, maybe it'll eventually stop snowing. Could you imagine 60 years from now, ads on tv...."come and spend 2 relaxing weeks in tropical paradise...come experience ALASKA!"

awesome!

Though we humans are putting a lot of stuff in the atmosphere but life on earth has increased along with our industrial revolution the living things on earth make way more CO2 then humans.


Suppose before 1,500 AD, the Earth’s natural carbon cycle is given a value of level 5. Suppose human activity is now adding a value of level 3 to the carbon cycle. It seems reasonable to assume that whatever was happening at level 5, is going to be accelerated over time and increased in intensity or quantity when running at level 8.

Given we cannot halt much of our activity, even a reduction of our contribution from level 3 to level 2 might prove worthwhile.


Though the data collected from vostoc and other ice cores do not match up showing that they are not reliable sources.


Reading ice cores is much more difficult than counting tree rings, I admit. OTOH, I’m not sure it is necessary that 2 or 3 cores should have to ‘match up’ before the information that is contained in each core is assimilated into a general theory of what happened.

Some parts of the polar ice caps are melting, other parts aren't, and still other parts continue to grow. I doubt that there is some magic number of ozone concentration at which the caps will have a dramatic melt increase. The ozone really protects us from radiation, not heat.
