The Changing data at NASA-GISS and our BoM, CSIRO

Back in August 1999, NASA-GISS had a web page about where would the US climate go. (Link in title above.)

At that time James Hansen et al wrote
Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s "Dust Bowl" that caused an exodus from the prairies, as chronicled in Steinbeck's Grapes of Wrath. Figure 1 compares the temperature history in the U.S. and the world for the past 120 years. The U.S. has warmed during the past century, but the warming hardly exceeds year-to-year variability. Indeed, in the U.S. the warmest decade was the 1930s and the warmest year was 1934.

Steve Goddard at Real Science, in a post called Data Corruption at GISS, exposes how the above graph was corrupted on NASA-GISS but is now restored. Steve has a blink comparator which shows that although, in the US graph above, 1934 was warmer than 1998, history has been rewritten and now 1998 is shown to be warmer than 1934.

So? You ask. Why are you reproducing Real Science. Well many claims have been made about 2010 being the warmest year. Perhaps not - see HERE and HERE

Makes NASA-GISS look suspect. 

How accurate and truthful are Australia's bodies, The Bureau of Meteorology and the CSIRO?

We should soon find out. Joanne Nova and a team of skeptical scientists, citizens, and an Australian Senator have lodged a formal request with the Australian National Audit Office (ANAO) to have the BOM and CSIRO audited.  (LINK

The BOM claim their adjustments are “neutral” yet Ken Stewart showed that the trend in the raw figures for our whole continent has been adjusted up by 40%. The stakes are high. Australians could have to pay something in the order of $870 million dollars thanks to the Kyoto protocol, and the first four years of the Emissions Trading Scheme was expected to cost Australian industry (and hence Australian shareholders and consumers) nearly $50 billion dollars.
