NOAA May Data Posted: Down from April.

7 Comments

NOAA’s May anomaly is 0.5225C down from 0.5990C currently recorded for April and also down from 0.6050 C reported for April during May.

Figure 1: NOAA Temperature Anomalies.
Figure 1: NOAA Temperature Anomalies.

Anomalies with trends since both 2000 and 2001 are shown above. The trend since 2001 is negative. The trend since 2000 is positive, but less than the nomimal IPCC trend of “about 2C/century.” Are you wondering about the trend since the La Nina trough in 1999? It’s 0.14C/decade, also lower than the IPCC “About 2 C/century”.

More later when Hadley posts.

  1. Lucia,

    ” The trend since 2000 is negative. The trend since 2001 is positive,…”

    Might this be backward??

  4. WE really need guys like B Tisdale to keep them honest. Nearly all the NOAA data (ice, temps, etc) seems to becoming junky lately. The only reliable temp/ice data in my biased view are RSS UHA, DMI and NANSEN (only lately though NANSEN seems they don’t want to be part of the charade anymore LOL)
    If adjusted for UHI according to A watts, maybe GISS, HADCRUT etc might be considered remotely close to being reliable.

  5. Geoff: Here are the temperaures cut and pasted:
    2009 1 0.5469
    2009 2 0.5048
    2009 3 0.5392
    2009 4 0.5990
    2009 5 0.5225

    So, 0.5990C for april.
    VG– There is no reason to suspect the data jumping around currently is due to bias.

  6. It seems that we are going to have to see one hell of a temp (atmospheric) jump from now on to stay above 0 anomaly for the rest of the year. One hell of a prediction I admit!

    Check ALL channels.
    Lucia: Probably right re temp/ice data jumping around now NOAA and NSIDC ..but there is definitely is a surface UHI temp bias (refer to WUWT ad infinitum…)
