I have debated within myself whether to reveal and write about this, but after some reflection I feel I have to.
I think Judith Curry lied in a 2010 paper about the temperatures in the Southern Ocean.
I don''t say this lightly. I've looked at the data several times now. I don't know what else to conclude.
Curry published a paper with Liu in 2010:
“Accelerated warming of the Southern Ocean and its impacts on the hydrological cycle and sea ice,” Jiping Liu and Judith A. Curry, PNAS 2010
That paper claims:
"The observed sea surface temperature in the Southern Ocean shows a substantial warming trend for the second half of the 20th century."Except, it's very easy to download the data and show for yourself that the Southern Ocean SSTs are actually cooling, as Bob Tisdale did here.
You can easily verify this for yourself. The SST data is here. Pick the region from 60 South to 90 South. I did this myself, with the time series starting in 1/3/1990 and ending in 1/29/14, the end date chosen because it was the time I was researching my article.
I found that, over this time period, the Southern Ocean SST changed by -0.082°C/decade, with a statistical uncertainty of only ± 0.001°C/decade (OLS only, no autocorrelation), for a total cooling of -0.19°C over this interval.
So how did Liu and Curry find warming? I really have no idea. It's certainly not a result I trust, and I have some serious concerns that their calculation is fraudulent and that their paper is incorrect, and purposely misleading.
Why? I don't know, at this point. I'm interested in hearing speculations in the comments.
