2010 On Track to Being 2nd Warmest Year Since 1880

In this post I present a 5 panel trend charts which show the year-to-date  anomaly trends for the 5 major global temperature anomaly series and a table that shows how  2010 YTD ranks over the entire record for each series. The source data and RClimate script file links are provided.

The 2010 GISS YTD  is the highest in the 131 year record. Both of the satellite anomaly series, RSS and UAH, and the Hadley and NOAA series had their  2nd highest YTD  anomalies in 2010,  1998 had the highest YTD for these 4 series.

Please not that the plots show the climate agency monthly anomaly values with respect to each agency’s  baseline period. For RSS and UAH, that is 1979-1998. For GISS it is 1951-1980 and for NOAA and Hadley, it is 1961-1990.

  1. I do not really know much about this stuff, but it appears to me that NOAA is saying January through October, 2010 is the warmest on record:


  2. When I see long-term trends like this, I often wonder what this would look like with the measurement error overlaid for each point (maybe as a grayed and alpha-blended “ribbon”). Do you know if the measurement error for historical measures of the temperature anomaly is known?

  3. 1) In line 16: temps <- subset(temps, temps$yr<= cur_yr & temps$mo <= which_mo) the objects ‘cur_yr’ and ‘which_mo’ do not exist (yet).
    To run, I replaced ‘cur_yr’ with ‘last_year’ and moved line 16 to after line 19: which_mo <- temps$mo[length(temps$mo)]

    2) The function ‘addtable2plot()’ requires plotrix package.

      Thanks for the quick double check of my script.

      I’ve made the noted changes.

      Can you retry to make sure I got them ?
