MIT research shows the hole in the Ozone Layer might be healing

I swear i remember hearing about the hole in the ozone layer shrinking years ago

You probably did. This is just another piece of evidence of the ozone hole shrinking, one of the best yet. It's worth noting the ozone layer fluctuates a lot through the seasons, and has random variations from year to year as well, so it's more like a pile of evidence gradually building up than suddenly flipping from no to yes.

Can you elaborate and post a source about NASA "fucking up"? I'd be curious to see what you're talking about.

In the late 70 to mid 80s, satellites were measuring the ozone concentration over Antarctica, but failed to notice the growing ozone hole because the software was programmed to ignore readings considered unrealistically low outliers - even after those readings became the norm.

Hah, they probably were programming the software with a primitive form of self diagnosis. Guess they never expected us to fuck the Ozone as much as we did.

Here's a source btw.

I have heard this before, maybe not from the same source, but I have defiantly heard this like two years ago or something.

 

EDIT: confirmed by someone else

Engine emissions cause global warming, not thinning of Ozone. Trust me, we have a huge reason to stop using fossil fuels as quickly as possible. Repairing the ozone layer will not do us any good if we are all drowned by melted ice.

Below is a proposed depiction of IF the worlds entire ice caps were to melt and this was done with an error margin of 5%-8% greater to show worst case scenario. The ice melting and the drowning the world myth can be disproved with a glass of water and an ice cube. [wrong analogy]

Anyone else here believe in the Gaia Theory? I feel for something like this it could be relevant. I know the hole is fixing because of reduced CFC's in the atmosphere but wouldn't it be interesting to learn that organisms are destroying them? It could be an example of Gaia Theory.

Considering the population of the world that lives within 75 miles of major waterways (the ones most likely to dramatically expand) that picture doesn't quite tell the whole story. Depending on the way the land slopes it could be literally no one affected, or all of Florida being swallowed up. New York already has flooding issues without any changes.

 

Yeah, its not going to be Waterworld, but it sure is going to fuck everything up.

Ill add the source. But yeah it doesn't show the whole story.

Ok but that still doesnt account for the actual impact on human life: http://www.un.org/esa/sustdev/natlinfo/indicators/methodology_sheets/oceans_seas_coasts/pop_coastal_areas.pdf

 

40% of the world lives along water lines that would be impacted. Whoever wrote your source didnt bother thinking about his final comment at all. " It is sad that some youngsters think that burning of hydrocarbons could cause the ice caps to melt and drown cities; it is criminal when teachers don't correct this nonsense." Considering its generally acknowledged to be the case that hydrocarbons do contribute to global climate change (other than a very vocal minor percentage) and his own data proves that if the ice caps do melt it would literally drown STATES not cities...

 

Granted, its dated from 2005, and a lot of data has come out since then about our impact on the climate, and how much of a problem it might be. Im not sure id use that guy's info as a reliable source of data. The paper i referenced was written only a few years later i believe (couldnt find the exact date, but check the references they are all 05-07) but implies a hugely different conclusion.

google something about biggest software bugs in history of IT,

long story short, NASA had their systems configured to not report any measurements that were way out of spec and for a couple of years nobody knew there was an Ozone hole forming, because their system filtered it out because  the amounts of radiation measured were deemed to be impossible meaning either the sensors are faulty or it's a noisy measurement

and then some British university guy accidentially stumbled upon it

Engine emissions cause global warming is inaccurate statement in my opinion. What about other facts? Such as cow shit and farts? That's right... Agriculture... #cowspiracy

Very interesting documentary boys and gals and here are some facts: http://www.cowspiracy.com/facts/

That documentary is on Netflix. I'd suggest to watch it, it was very interesting, for me.

The difference there is that agriculture is a necessity and part of the natural climate. Car emissions are not...

Well, that is up for some debate on the agriculture front. It might be considered a necessity but it is 100% human influenced. There are a lot of studies out there that are investigating if its even possible for us to reduce our emissions and natural resource usage while being able to maintain the same production of food and it hasn't produced much results. Its also a big argument of a lot of people going vegan, the whole deal about how much water, grain and land is needed to create a pound of beef in comparison to other foods.

 

That being said, it is much easier to curb car/transport emissions on a global scale with less of an impact to life, so that's where a large majority of awareness is focused.

And all the meanwhile the Polar icecaps have actually grown, as has Antarctica.  Some glaciers have sunk and some new ones formed.  I'm still getting that Corvette Z06.  *_*

ummm... Ozone's protecting us from radiation and shit... we got a hole in it because of these:

 

It's going to heal quicker than normal due to power grids and transformers inefficiencies funny enough, since arching electricity is what creates ozone on earth, but normally only lightning would cause it.

Its not really worth me getting into this debate much, but going vegan is hardly viable as its generally not very healthy at all. We are omnivorous...

Its not a case of being easier. Because it sure as hell is a a lot harder to get people to give up their cars for lower emission cars. Its simply because vehicles are the leading cause. Agriculture is again natural. Yes a lot of it is human influenced but that doesn't put it any where near on the same scale and transportation which is completely human influenced and totally unnecessary these day.

Looking at agriculture is not going to solve our problems and going vegan is just going to cause a lot more issues.

No what he is saying is actually correct when talking about Antarctica, the north pole however is a different story.

Yup. And here in south Africa we're experiencing a massive drought with record low rain.

This time two years ago same we're overflowing. Now they're at 30%, during the rainy season.

TL:DR the oil and coal industry needs to die, before we do.

If you put an ice cube into a glass of water, then the water level will not change as it melts. But that's analogous to sea ice melting. The analogy to land ice (ice caps) melting is holding the cube above the glass and watching the melt water drip into the glass. Then the water level will rise.

[RuffRuffmcgruff]

Let's hope we don't blow our selves up in the next 10 years. We should be gravy, if not for all the other external threats out there.

[Murasaki]

That's cool. But Earth's global temp is still rising. We still got a long way to go to stop all the factors causing it, and hopefully in time

there are other things that make ozone apart from Electric sparcs

naturally in the upper layer of athmosphere it's the ionizing radiation from the sun,

down here in the lower athmosphere ozone is unstable and it never reaches the upper layers to join the big Ozone layer and protect us...

Yes, sorry I used the wrong analogy, I will remove it. When I typed it up I was thinking of the sea ice ... my bad  [brain fart]

This is obviously not a thread to talk about global warming. But I wanted to tell you that natural doesn't mean it's not causing a problem, it can be 110% natural, but if it causes the problem then I rather go with not natural. Unfortunately, Agriculture "the natural as you describe" is leading cause for global warming not vehicles, (in English accent) mate.

What I'm more interested about is what happened to chlorine ? cause from looking at the reactions that happen it looks like chlorine gets reused every time.
