more spin and BS.
In other words: "someone is saying something I don't agree with! ZOMG, ZOMG, ZOMG!"
I linked you to data that shows that the ozone layer is not getting any smaller after years of negligible CFC emissions. you claimed that we had managed to start "slowly repairing damage to the ozone layer"
No you didn't - you linked us to a poorly written article on the leading climate change denialism site, by someone who isn't a climate scientist, which suggests that the mean area of the ozone hole was at its fourth largest recorded size ever recorded, despite the fact that use of CFCs has been reduced to nothing.
In response to this copy-pasted article, I explained why the article is inaccurate and what the flaws are: it isolates one metric, and pretends that it's the only relevant one and then focuses on a single measurement of that metric to somehow suggest that our efforts have failed. It then extrapolates, from that, about global warming.
Listen, if you consider that article serious and accurate, then good for you.
link us to the data that shows this
We have started to slowly repair damage to the ozone layer, and the data bears this out. Hell, the chart in the article you linked to bears this out: as the consumption of ozone-depleting substances fell, the slope of the line depicting the size of the ozone hole area changes dramatically. Applying a smoothing filter to smear out yearly variations makes this observation even more clear.
Also, according to
NASA: "Records in depth and size haven’t occurred during the same years (the largest ozone hole occurred in 2006), but the long-term trend in both characteristics is consistent:
from 1980 through the early 1990s, the hole rapidly grew in size and depth. Since the mid-1990s, area and depth have roughly stabilized (see the Ozone Hole Watch website for annual averages). Year-to-year variations in area and depth are caused by variations in stratospheric temperature and circulation. Colder conditions result in a larger area and lower ozone values in the center of the hole." (emphasis added)
i believe they only found the hole in 1979....who's to say how long the hole was there before that? who's to say how it had changed in size pre 1979?
Well, that's a great argument: you can't prove the ozone hole wasn't there forever or that its size is affected by CFCs and not by ninjas, therefore ninjas!
I simply look at the data and the best theories we have available to us. Science is simple: formulate a theory, then use it to make predictions and see how well those predictions hold up; if they do, great... repeat. If they don't, then either adjust the theory to account for the discepancy or come up with a new theory; start again.
after reducing CFCs to near zero for some years the hole is not showing any sign of getting smaller in fact it is now at it's 4th biggest size since we first it 1979....
See above snippet from NASA.
with that in mind who is to say CFC emissions actually played any significant role in the hole in the 1st place....pretty straight forward logic really...
You're right... despite the evidence and the well-understood chemistry and the experiments which confirm the harmful effects of CFCs on ozone, it's not CFCs. It's ninjas instead.
you think it is down to humility that no one is claiming any credit for the great work done in reducing CFC emissions and fixing the ozone layer?
Well, ninjas work in the shadows...
