1998 Climate Shift

I was looking at some time series data in particular SH ozone and the AAO(SAM)

I noticed a clear and abrupt change around 1998 and onwards.

I thought l might check Google to see if researchers had documented a climate shift and the answer was yes.

There have been major climate shifts noted in 1925,1945,1975,1998

( BTW..when  was searching for information on google for ‘climate shift’, l noted l got next to NOTHING..,It appears google have removed the term and given full priority to the term ‘climate change’.

I think l might change my search engine)

    Of course the AGW sites will say the hydroflurocarbon ban has restored levels of ozone but l suspect there is a longer term driver/s
