GISS June global temperature up by 0.14°C from May.

The GISS V4 land/ocean temperature anomaly was 1.07°C in June 2023, up from 0.93°C in May. This rise is nearly the same as the 0.142°C rise reported for TempLS.

As with TempLS, June was by a large margin the warmest June in the record - next was 0.92°C in 2022. As mentioned in my last post, I now have on the data page a maintained table of months in descending order to facilitate these comparisons. Here is the GISS monthly average anomaly:

There seems to be ongoing warming, if you let your eye follow the red "23" squares. Since the annual to date is close to the hottest ever, it is likely 2023 will end up on top.

As usual here, I will compare the GISS and earlier TempLS plots below the jump.

Maintained table of global temperatures listed in order for each calendar month.

I currently post automatically updated monthly temperatures in various forms on a Moyhu page. In fact, I keep the updated database of various major sources as a CSV file here:
It is the record as it stood in that month; just make the obvious changes to the date in the URL to get other months.

One of my tasks in posting the monthly temperatures is to look up where that month stood in the ranking of months. I have now made a maintained table which shows temperatures in ranked order (top 10) for each calendar month, for TempLS and various other sources (scroll down). It also shows the annual average (to date, for the current year). Columns contain a two digit number of the year, and then the anomaly average, in whatever anomaly base is used by the source. TempLS is 1961-90.

June global surface TempLS up 0.142°C from May.

The TempLS FEM anomaly (1961-90 base) was 0.95°C in June, up from 0.808°C in May. It was the warmest June in the record, well ahead of 0.801°C in 2020. The NCEP/NCAR reanalysis base index rose by 0.09°C.

Most of the world was warm, with a cooler band across the southern US, and in western Russia. The Pacific W of Peru was warm.

Here is the temperature map, using now the FEM-based map of anomalies.

As always, the 3D globe map gives better detail. There are more graphs and a station map in the ongoing report which is updated daily.
