BBC News - Ozone hole has dried Australia, scientists find
The Antarctic ozone hole is about one-third to blame for Australia’s recent series of droughts, scientists say.
Writing in the journal Science, they conclude that the hole has shifted wind and rainfall patterns right across the Southern Hemisphere, even the tropics.
Their climate models suggest the effect has been notably strong over Australia.
Australia is currently experiencing 0% drought, and John Cook blames the recent decline in sea level on excess rain in Australia.
Scientists apparently had large ozone holes in their brains from 1920-1960.

global warming effects sea level, the scientific cause of a drought

There is also the rising trend in carbon dioxide, and that is acting in the same direction as the ozone hole”

The rising trend in CO2 levels correlates with population rise, even though nearly all population rises happen in under-developed countries. (1billion people rise, 20ppm rise in CO2)
Maybe ozone holes correlate with population.

Followed by some blather about weather in the UK -
These high-altitude winds are key to determining weather patterns, in both hemispheres. Much of the cold weather felt in the UK over the last couple of winters, for example, was caused by blocking of the Northern Hemisphere stream.

“The Columbia team found that overall, the ozone hole has resulted in rainfall moving south along with the winds.
But there are regional differences, particularly concerning Australia.
“In terms of the average for that zone, [the ozone hole drives] about a 10% change – but for Australia, it’s about 35%,” Dr Kang told BBC News.”

So it’s a scientific fact that a hole in the ozone causes rain? There is of cause a peer reviewed scientific paper that shows this, isn’t there? Or is this just correlation proving causation?

“Their modelling indicated that global warming due to greenhouse gas emissions was also a factor – although natural climate cycles are also thought to be important, as Australia suffered severe droughts in the era before ozone depletion and before the warming seen in the late 20th Century.
“This study does illustrate the important point that different mechanisms of global change are contributing to the climate impacts we’re seeing around the world,” observed Professor Myles Allen of Oxford University, a leading UK climate modeller.
“It’s very important to unpack them all rather than assuming that any impact we see is down simply to greenhouse gas-mediated warming.”"

So the study shows that by opportunistically throwing in unvalidated data into a computer model can cause impacts to modelers the world over. And of cause the last line does say they wouldn’t jump to any conclusions even though they had.
You believe that and I got a computer model to sell you!
Wait. John Cook actually admits sea levels have been declining? BUT BUT BUT…HIS SITE SAYS THEY’RE RISING! D8
Also, I love how they blame CO2 for everything. Jeez, who knew a gas could get so much attention.
I guess these well trained, expert scientists do not consider the same factors that control the size and existence of the Ozone Hole may also result in the weather patterns in the Southern Hemisphere. I always enjoy it when an over educated fool thinks the dog barking makes the car go by or the coyote howling makes the Moon full.
