I see. "Same chart" with completely different data. I don't think you know what the word "same" means.Same chart, new and improved calculations that are more accurate.
Indeed, NASA says it "switched" from one data set to another: http://data.giss.nasa.gov/gistemp/updates_v3/ersst4vs3b/. That confirms that they're not the same.
Indeed, the ERSSTv4 chart didn't even exist when we made the bet in May. The bet was on the ESSRTv3b graph.
If you insist that the ESSRTv3b bet "stands," then there is no reason to wait until the end of the year to determine the results, as NASA has confirmed there will be no further updates to the ESSRTv3b chart.
The final tally for 2015 on the ERSSTv3b was 0.766 degrees Celsius.
You bet on a minimum of 0.83 degrees Celsius.
You lost.
I look forward to your reviews.
