DATA VAN DE DAG - The world has been warming for some time now. But due to a strong El Nino the warming in 2015 and 2016 will be even higher. How much higher? We show the graphs from the five major surface based measurements sets.

First of the sets to be published was the one from Berkeley University. The reference period is 1951-1980. We use the serie where the sea ice temperature is inferred from the air temperature. The previous record was from 2014 with 0.66℃ above average. The new record set by 2015 is now 0.79℃. The graph is shown above.

The second set is from NOAA/NCDC. The previous record was 0.74℃ in 2014. 2015 set a new record with 0.89℃.

The third set is the one from GISS (NASA). Previous record was 0.74℃. The new record is 0.87℃.

The fourth set is from the MetOffice (HADCRUT4). The previous record was 0.57℃ in 2014. Now it's 0.75℃.

The last set is the one from the Japanese Meteorological Agency (JMA). With them the previous record was from 2014 as well. That was 0.27℃. The new record, based on the preliminary data for December 2015, will be 0.42℃.

Their reference periode is 1981-2010. The graph at the bottom below shows the yearly values since 1979.
