When they upgraded those historic readings 1995 went from a reading of 0.43ºC to 0.46ºC.
So lets check that math:
0.2 X 2 =0.4 (two decades at 0.2/decade)
0.46 +0.4= 0.86 (1995's adjusted NASA temp plus the IPCC projection = moviefans 'adjusted' bet he tried to change it to of 0.86ºC
NASA reported 2015 @ 0.87ºC, which is more then 0.86ºC.
You've made a start, but you conveniently ignored all of the facts that throw a wrench into your math.
Let's look at the NASA revisions in more detail.
We cited the anomalies for two years in the original May bet -- the anomaly for 1995 and the anomaly for 2014. Let's look at what happened when NASA changed the weighting of its ocean temperatures.
-- The 1995 anomaly went from 0.43ºC to 0.46ºC -- a change of 0.03ºC.
-- The 2014 anomaly went from 0.68ºC to 0.74ºC -- a change of 0.06ºC.
The increase in 2014 and other recent years was
double the increase for 1995 and other years in the 1990s.
So what are we to do with that difference of 0.03ºC?
Frankfooter thinks the answer is to simply ignore the difference. But whether he understands it or not (with Franky, you can never tell), that is blatantly dishonest. The difference matters, particularly as it represents a 20% cut in the size of the bet from 2014 to 2015.
Frankfooter's calculations simply award that 0.03ºC change to Frankfooter, wrapping it in as part of the IPCC's predicted "temperature" increase.
It is nothing of the sort.
The bet we made was on the IPCC's predictions of temperature increases that were supposed to be produced by man-made emissions. We weren't betting on numerical changes to past years that were created by a change in methodology.
That 0.03ºC difference is
not a temperature increase. It does not count toward the bet.
To bring the 1995 anomaly in line with the original bet, you need to add that 0.03ºC difference to the 1995 anomaly. That brings the corrected (for the purposes of the bet) 1995 anomaly to 0.49ºC.
Add in the wager of 0.40ºC over two decades that was in the original terms, and you get a revised bet of 0.89ºC -- the
exact same number you get when you add 0.15ºC to NASA's newly adjusted anomaly of 0.74ºC for 2014.
When you do the math correctly, you get a revised bet of 0.89ºC -- regardless of whether you use 1995 or 2014 as your starting point.
The final 2015 anomaly of 0.87ºC at the end of the super El Nino year was less than 0.89ºC.
Applying the original terms to the new data -- as Frankfooter has spent weeks arguing for -- shows the final anomaly is less than the minimum increase we bet on.
Frankfooter lost the bet.
More significantly, he has lost the argument.
