Every month since March, I've posted a chart of the progressive year-to-date global average surface temperature, from GISS. This is the update with December included, so it's the final for the 2015 year. The explanation has been included with each update together with what seem to be things to watch. The next article will be in April (to March) or May.
The main article for the 2015 year can be found here.

Watching the global thermometer - year to date GISTemp with a very hot October 2015

Wow! I knew that the Japan Meteorological Agency showed a big jump in October, and I expect GISS was doing some double and triple checking of the GISS data. October is the hottest October on record by a country mile. A whopping 1.04 °C above the 1951-1980 mean. This is the first time any month has an anomaly greater than 1 °C above the 1951-1980 mean (h/t Joe Stepansky).

Watching the global thermometer - year to date GISTemp with June 2015

NOTE: GISS has announced corrections and thanked Nick Stokes (see comments below). Refer to the updated version of this article.

Note: I made a mistake with the June YTD in the original, which I've now fixed. (Sou 9:00 am)
Update: I've added a chart of annual temps for GISTemp, comparing the version put out in June with the version put out in July. That's so that you can see what difference the shift to ERSST v4 makes.

Watching the global thermometer - year to date GISTemp with May 2015

This is the update of the progressive year-to-date global average surface temperature, from GISS. This update includes May.
The chart is a progressive year to date average for all years from 1995 to the present. What that means is for January each year, it just shows the anomaly for January. For February it shows the average of January and February for each year. For March, its the average of the monthly anomaly from January to March.
If you look at December, each year shows the annual average temperature for the full year. For November, each year has the average for the year up to November, not including December. (As before, I've made it extra large because of all the fine detail.)
2015 is still ahead of the pack so far, just ahead of 2010 for this time of the year. The years to watch are 2014, 2010 and 2005. I've plotted them with slightly thicker lines so they stand out more easily.
The coldest year of the lot was 1996, which still ended up more than 0.3°C above the 1950 to 1981 average. The next time someone tries to tell you that "it hasn't warmed since 1996" then show them this chart :)
I promised to provide a data file because the chart is so messy. You can access it here on Google drive.
Watching the global thermometer - year to date with April 2015 and the same with YTD to March this year.
Worth noting
- May was an average of 0.71°C above the 1951-1980 mean.
- April was adjusted back to 0.71°C from 0.75°C
- May this year was equal second hottest with May 2012.
- Every month this year has been at least 0.71°C above the 1951-1980 mean.
- The progressive year to date average up to and including May is 0.77°C above the 1951-1980 mean.

YTD including May
Worth noting
- April was an average of 0.75°C above the 1951-1980 mean.
- From and including December 2014, every month has been the second hottest in the record for that month, except for March 2015, which was the 3rd hottest March on record.
- Every month this year has been at least 0.75°C above the 1951-1980 mean.
- The progressive year to date average up to and including April is 0.79°C above the 1951-1980 mean.

Watching the global thermometer - year to date GISTemp

There was some discussion on a previous thread about how much the earth may warm this year. I know it's a bit soon, but figured it might be interesting to see how things are faring.
If I remember, I'll post an update to the chart below each month, after GISTemp data comes out.
The chart below is a progressive year to date average for all years from 1995 to the present. What that means is for January each year, it just shows the anomaly for January. For February it shows the average of January and February for each year. For March, its the average of the monthly anomaly from January to March.
If you look at December, each year shows the annual average temperature for the full year. For November, each year has the average for the year up to November, not including December. (I've made it extra large because of all the fine detail.)
2015 is ahead of the pack so far, though it only goes up to March. The years to watch are 2014, 2010 and 2005. I've plotted them with slightly thicker lines so they stand out more easily.
The coldest year of the lot was 1996, which still ended up more than 0.3°C above the 1950 to 1981 average. Incidentally, the potty peer, Christopher Monckton keeps saying that "it hasn't warmed since 1996" - the drongo. He's got his temperature charts upside down :)
