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 :)
