the latest US satellite figures showing temperatures having fallen since 1998, declining in 2007 to a 1983 level – not to mention the newly revised figures for US surface temperatures showing that the 1930s had four of the 10 warmest years of the past century, with the hottest year of all being not 1998, as was previously claimed, but 1934.
A quick look at a graph of the satellite-measured temperatures exposes Booker’s cherry picking:
Temperatures have been rising steadily at 0.178 degrees per decade, but with fluctuations above and below the trend line. If you study the graph closely, you’ll see that there was one month in 1983 (during an El Nino event) which was warmer than a couple of months in 2007. Comparing a couple of months instead of looking at all of them is deceitful, but seems to be the usual practice at the Telegraph.
The second part of his sentence is misleading as well, since NASA never claimed that 1998 was the warmest year in the US.
