Climate FAIL: GISS is presenting 2012 US temperature as 'off the chart', while preventing older data from being archived

UPDATE: 8/22/12 9AM The problem has been solved, GISS responded to my complaint -Anthony Like the erroneous graph at California Governor Jerry Brown’s climate denier slam site,  here’s another one of those things that I’ve been sitting on for about a week, waiting for somebody to fix it. Since they haven’t, and I’ve given adequate…

July was also the 329th consecutive month of positive upwards adjustment to the U.S. temperature record by NOAA/NCDC

I’ve noticed there’s a lot of frenetic tweeting and re-tweeting of this “sound bite” sized statement from this Climate Central piece by Andrew Freedman. July was the fourth-warmest such month on record globally, and the 329th consecutive month with a global-average surface temperature above the 20th-century average, according to an analysis released Wednesday by the…

Has the CRUTEM4 Data been fiddled with?

Guest post by Ed Thurstan Abstract It is apparent from the data that CRUTEM4 temperatures adjustments have, in part, been made with reference only to the earlier CRUTEM3 data, rather than raw temperature data. Further, the adjustments depend on the month for the data, and these adjustments are made for 20 or 30 consecutive years.…

Tisdale on Polar Amplification

Polar Amplification: Observations versus IPCC Climate Models Guest post by Bob Tisdale We’ve illustrated and discussed polar amplification in a few posts in the past. See here and here. Wikipedia has a short blurb about it: Polar amplification is the greater temperature increases in the Arctic compared to the earth as a whole as a result…

How reliable are global temperature "anomalies" ?

Guest post by Clive Best Perhaps like me you have  wondered why “global warming” is always measured using temperature “anomalies” rather than by directly measuring the absolute temperatures ? Why can’t we simply average  the surface station data together to get one global temperature for the Earth  each year ? The main argument to work…

UCAR on Blocking Highs, heat waves, and modeling limits

Dr. Roger Pielke Sr. writes: Candid Admission By UCAR – “Blocking The Way – Predicting The Atmospheric Detours That Lead To Weather Troubles” There was an interesting article in the Fall issue of the UCAR Magazine titled by Bob Henson titled Blocking The Way – Predicting The Atmospheric Detours That Lead To Weather Troubles Although embedded in the article…
