Perhaps I am reading it wrong, but that study seems to be saying that, after reviewing fifty years of data they have discovered that seasonal variations in
temperature across the globe are heavily influenced by the Southern Oscillation Index.
It doesn't actually appear to be saying anything about global mean rise in temperature. It is saying that the SCI produces a noticeable change in
temperature that can account for a few anamolies in the existing literature. I suppose if you squint and read it incredibly loosely you could say it has anything to do with global climate change.
