The record year 2015 and what helped

Below is just a machine translation from the German of Frank Bosse und Fritz Vahrenholt.  I didn't feel like tidying it up as I think the messages get through anyway. They note that 2015 officially was thirteen hundredths of a degree warmer than 2014 and ask why. They make the obvious point that El Nino was a big contributor but what I think is of particular interest is their attack on the retrospective and controversial "adjustments" to ocean temperature by Tom Karl -- adjustments that wiped out the "pause".

Bosse and Vahrenholt below use the Argo floats to test the changes.  They find that for the period covered by the Argo floats, the "old" temperature statistics match the Argo record better than did Tom Karl's adjusted statistics.  Since the Argo floats provide the best ocean temperature record by far, it is clear that Karl's adjustments are not validated.  The "old" measurements are the best and the "pause" is back!

The last sentence below is also very interesting.  The entire terrestrial record may by now be too corrupt for any reliance to be placed on it


The 2015 ended with a record: The temperature range GISS recorded +0.87 ° C anomaly compared to the reference period 1951-1981. These were further 0.13° C was observed over the previous year in 2014 globally. They rose strongly on ocean temperatures. A look back at a few months earlier record GISS of May 2015 shows that the global mean temperatures were 2014 then still appear lower by 0.06 ° C than in January 2016.

How can that be? In summer 2015, a correction of ocean temperatures was introduced, we had, among other things here reported. The trigger: The measurement methods for detecting the surface temperatures of the oceans (SST Sea Surface Temperature) changed from 1998. Whereas previously the SST determined from ships, often by the water temperature was measured in buckets or the sucked cooling water, you went to later precise measurements over buoys. This transition was, according to the scientists to T. Karl. By NOAA, a negative distortion, which is minimized (for obvious to warm measurements of the past down to the precise measurements of the presence of upward) with corrections This measure was taken very quickly for the global soil temperature series.

We want to assess the validity of the corrections by T. Karl shortly. As a reference, we use the most homogenous temperature range that is available for sea surface temperatures: The buoy measurements of the Argo program , which since 2004 provides fairly accurate and closely defined data error. We consider the temperatures of the upper 100m globally and comparing the uncorrected series ERSSTv3b and the realigned series ERSSTv4 (NOAA).


Figure 3: The annual mean SST for ERSSTv3b (v3b- black) and ERSStv4 (NOAA red) and the reference of Argo measurements (NODC- blue) with the resulting linear trend of global SST.

It is striking that the trends for the unadjusted series (black) and for very precise reference number of the buoys measurements (blue) are virtually indistinguishable, the adjusted series (red) but provides a stronger by about 50% rising trend since of 2004. The difference is caused by lower values ​​in the past, and slightly higher in the present. The comparison with the most modern and authentic data on sea temperatures in any case does not justify the correction of the SST by T. Karl. To record in 2015 was the introduction of the new SST-series at about 0.04 ° C.......

Moreover, the satellite measurements of the troposphere show no record increase: both series of measurements, both UAH and RSS, enter 2015 just as the third warmest year since 1979. That the troposphere temperatures rise more slowly than soil temperatures is a state of affairs that does not reproduce the climate models. You expect it the other way around.
