As we all know the weather in both, northern and southern hemispheres, has been changing for the last 10 years. Very cold winters, storms, floods and draughts are creating havoc all around us. After what it was a very cold winter here in the UK, we now have had the hottest April on record and it has not rained (as it should for this time of year) at all. In fairness it felt more like June than April. Most people in the UK see this as a good thing cause, after all everyone prefers sunshine to weeks of grey skies and rain.


I have followed the Ozone layer depletion since it was first publicly announced back in the 80's and after the initial alarm/panic, doom and gloom, wear sunscreen media frenzy everything went quiet. Yes, we all know there is a hole in the Antarctic but what hardly anyone knows is that we have now got another hole in the Arctic. This new hole was already forecasted back in 2000 but at that time they predicted the hole to form by 2020.

Well, here you have an article confirming how the Hole is affecting the weather patterns in the southern hemisphere.
http://www.bbc.co.uk/news/science-environment-13161265


By logic the hole in the Arctic must also be affecting the weather patterns in the northern hemisphere. We know also that the Jet Stream has been 'out of place' for 3-4 years now and you can see how irregular and how far south it reaches currently in here (use the archive animation to see it better):

My two cents as to how the Ozone layer (or lack of it) affects the Jet Stream and consequently the weather patterns? well, think of the Earth as layer upon layer of mater with different densities. Heaviest at the core and working the way up to the Stratosphere to the much less denser mater layers. By removing this layer (or part of it), more cold from space is allowed in, which cools the higher atmosphere further (to a record level in the Arctic this year). As cold air sinks, it makes its way southward (northward if you live in the southern hemisphere ;)) creating pockets of cold air (you can see this easily in any met map or even on the Jet stream link above). These pockets are now reaching further than never before and as they push their way down they push the Jet stream along with them. Equally so, warm air raises and the vacuum left by the cold air moving south it’s filled in by a pocket of warm air travelling north. The combination of both have given the Jet Stream a very extreme wave like pattern reaching, like I’ve said, further towards the equator as never before. Florida saw record cold temperatures this Winter just gone.
In conclusion, altough the signs are very obvious not a lot is being done in terms of awareness by the powers to be. Back in the 80’s it was Ozone this Ozone that till the sales of UV protectors sky rocketed... today even though it is worse than has ever been, no one seems to care.


So what do you guys and girls think?

Maybe no one actually cares unless of course HAARP, aliens and other conspiracy theories are involved... Looking at other Ozone topics I can see that there's little interest in it... clue given by the lack of replies from other members.

could be many factors, the near 1000 nuclear explosions we have set off, el nino, core warming, solar warming, hole in the ozone layer, holes from objects leaving earth (satellites, spacecraft)

HAARP!!!!! lol (but only slightly)

good research though, at least you went out and searched for yourself.

personally I think most of it has to do with our Suns interaction with our atmosphere, but we haven't had the capabilities to monitor the sun for this long and we haven't yet found correlations to activity on the sun to what happens here on earth. that and the frictional tides of the moon with activity of the sun.

I thought it was a proven fact that CFC's and other substances caused the hole...

yes, but many other factors can attribute to the depletion, like solar flares, they eat up the molecular structure of oxygen and put radiation into our skies in place of it...

basically eating the sky with each hit it takes,

but like most things, heat also rises as cold air sinks, and we have alot of heat emitting from our core and planet, and we also have renewable oxygen resources (trees and plants) that help to alleviate some of the negative effects of our state.

also you start off with reasons why the hole is there, then trail off into effects of global warming, which is what I addressed and addressed the reasons as to why we have holes, and why they are expanding in relation to our weather patterns and events happening on and outside of our planet...

hope that clears some things up about my statement.

I understand what you're saying but I'm not talking about the effects of global warming or going into the whether man made or not debate :wink: . More about the effect that the depletion of the Ozone is having on the Jet Streams (http://en.wikipedia.org/wiki/Jet_stream) and consequently to the weather patterns. Jet Streams have great influence on the weather as the move Atmospheric rivers (http://en.wikipedia.org/wiki/Atmospheric_river) across the globe (hence they are used for weather forecasting help). It is fact that the unusually cold winters we've had have been 'blamed' on to the Jet Stream:

http://www.irishexaminer.com/ireland/natural-shift-in-jet-stream-to-blame-for-cold-snap-140229.html although I wouldn't call it a natural shift.

http://www.dailymail.co.uk/sciencetech/article-1340436/Why-cold-warm-Greenland-Diverted-jet-stream-letting-icy-blast-Arctic.html

What caused the hole in the first place is not important as there are 2 holes already and scientists do not expect them to recover until 2050 2060. I think that is a loooong way away for a prediction. The Arctic hole was not expected till 2020 and in 2006 the claim that the hole would never match the Antarctic one and that would recover by 2030 2040 was made http://news.bbc.co.uk/1/hi/sci/tech/5276994.stm. In fact the Artic hole has broken records this year, so go figure. Of course it could be a case of it has to get worse before it gets better but with China and India (the largest to be economies) still churning out the main culprit (CFC's) into the air http://indiatoday.intoday.in/site/story/India+largest+source+of+smuggled+CFCs/1/7525.html so I doubt it will get any better any time soon... :lol:

Indeed. It's funny how some people are in denial about it. Switzerland has banned aerosols.
Greed has doomd us all.

I agree with you thruthseeker. We live within a veeeeery thin, fragile layer of air and people's denial and greed will not make the problem go away. I'm no fan of Al Gore but his analogy of the frog in boiling water springs to mind....

I think the premise of the OP is pretty reasonable, but I wouldn't go so far as to say any of these things are "proven", as the systems involved are too large and interdependent to model with predictive accuracy.

Worth considering, thanks for the post.

I come from Bournemouth, UK and i can confirm it rained last night.....and the night before....and the sky today is looking very grey
Let me take the waves out of the ocean
Let me take the stars down from the sky
Let me take the faith from your foundation
Let me take the wrong to make it right
Let me take away the dark like I’ve been here all night
Ending before I begin
