NASA GISS – Adjusting the Adjustments

Dec 26, 2010 – 10:42 AM

As a simple exercise, I quickly revisited the everchanging Hansen adjustments, a topic commented on acidly by E.M. Smith (Chiefio) in many posts – also see his interesting comments in the thread at a guest post at Anthony‘s, a post which revisited the race between 1934 and 1998 – an issue first raised at Climate […]

Y2K Re-Visited

Nov 11, 2010 – 10:53 AM

Long-time CA visitors will recall the events in mid Sept 2007 when NASA GISS made abrupt changes to US historical temperature data without annotation – a month after the Y2K changes. Some fresh light has been shed on these events by the NASA FOI. At the time, I observed: no wonder Hansen can’t joust with […]

Steig versus Hansen

Jan 31, 2009 – 11:53 AM

In Dec 2004, Steig and Schmidt wrote The Antarctic Peninsula, site of the now-defunct Larsen-B ice shelf, has warmed substantially. On the other hand, the few stations on the continent and in the interior appear to have cooled slightly (Doran et al, 2002; GISTEMP). At first glance this seems to contradict the idea of “global” […]

OK, What Caused the Problem?

Nov 16, 2008 – 7:59 PM

Are you like me and a little puzzled as to exactly how the GHCN-GISS problem happened? GISS blamed their supplier (NOAA GHCN). Unfortunately NOAA’s been stone silent on the matter. I checked the Russian data at meteo.ru and there was nothing wrong with it. Nor is there anything wrong at GHCN-Daily for stations reporting there. […]

Does Hansen’s Error “Matter”?

Aug 11, 2007 – 1:44 PM

There’s been quite a bit of publicity about Hansen’s Y2K error and the change in the U.S. leaderboard (by which 1934 is the new warmest U.S. year) in the right-wing blogosphere. In contrast, realclimate has dismissed it a triviality and the climate blogosphere is doing its best to ignore the matter entirely. My own view […]
