Waldo,
Did you read the paper itself?
How far back into the past are their data?
From post #302
Implications they have no idea about since the amount of data for this research field is negligible.How would they know it is "unprecedented"?
Chlorine has been in the atmosphere for a long time before CGC's were produced.
Do you realize that they left out the fact that there also similar low readings back in the late 1950's? Long before there were any significant CFC's being produced?
Dr Michelle Santee of Nasa's Jet Propulsion laboratory said, 'It was continuously cold from December to April, and that has never happened before in the Arctic.'
When will they stop calling it unprecedented? It is stupid!
They did tell us finally after reading the speculative crap they wrote.That it has been colder much longer than usual.
LOL
It stopped cooling about 20 years ago.
