A few years ago there was a big hullaballoo about ozone holes and how terrible they were and how they had to be prevented. Now that the thinning ozone is not so thin anymore look at what they are telling us.
The gradual repair of the ozone hole above Antarctica could warm the frigid continent by weakening the cold winds that protect it from tropical heat, says a new study.
Research published Thursday in the journal Science says the vortex of winds that ring Antarctica is at risk as the damaged ozone layer is restored.
“Although the rest of the climate is warming up . . . there’s been a cooling over the Antarctic plateau and a speeding up of the winds around the edge of the Antarctic,” said University of Toronto professor Ted Shepherd, who co-authored the paper with scientists from the United States, Switzerland and Japan.

It may be a surprise to many to hear that the Antarctic has been cooling as the press has been warning us about warming there. Now there is this new ozone “threat” if it is a threat. They admit they don’t know.
AND we note this interesting statement.
The Intergovernmental Panel on Climate Change’s most recent assessment didn’t include ozone recovery in its climate modelling.
Shouldn’t we know a little more before we shape our whole economy [and our municipal planning strategy] around these climate models? Do we really know how sound these models are? Some of the data , such as tree ring data, used to create them are already coming into question.
Dana Longcope, a solar physicist at MSU, said the sun usually operates on an 11-year cycle with maximum activity occurring in the middle of the cycle. Minimum activity generally occurs as the cycles change. Solar activity refers to phenomena like sunspots, solar flares and solar eruptions. Together, they create the weather than can disrupt satellites in space and technology on earth.
The last cycle reached its peak in 2001 and is believed to be just ending now, Longcope said. The next cycle is just beginning and is expected to reach its peak sometime around 2012. Today’s sun, however, is as inactive as it was two years ago, and scientists aren’t sure why.
“It’s a dead face,” Tsuneta said of the sun’s appearance. [take a look for yourself]
Tsuneta said solar physicists aren’t like weather forecasters; They can’t predict the future. They do have the ability to observe, however, and they have observed a longer-than-normal period of solar inactivity. In the past, they observed that the sun once went 50 years without producing sunspots. That period, from approximately 1650 to 1700, occurred during the middle of a little ice age on Earth that lasted from as early as the mid-15th century to as late as the mid-19th century.

Perhaps the tune will change and we will be asked to produce MORE CO2 to warm up the earth – as if THAT would work.
