Scientists at two of the world’s leading
climate centres – NASA and NOAA – have been caught out manipulating
temperature data to overstate the extent of the 20th century “global
warming”. ~ James Delingpole – Kit Eastwood
The evidence of their tinkering can clearly be seen at Real Science, where blogger Steven Goddard has posted a series of graphs which show “climate change” before and after the adjustments.
When the raw data is used, there is little if any evidence of global
warming and some evidence of global cooling. However, once the data has
been adjusted – ie fabricated by computer models – 20th century ‘global
warming’ suddenly looks much more dramatic.
This is especially noticeable on the US temperature records. Before
2000, it was generally accepted – even by climate activists like NASA’s
James Hansen – that the hottest decade in the US was the 1930s.
As Hansen himself said in a 1989 report:
In the U.S. there has been little temperature change in the past 50
years, the time of rapidly increasing greenhouse gases – in fact, there
was a slight cooling throughout much of the country.
However, Hansen subsequently changed his tune when, sometime after 2000,
the temperatures were adjusted to accord with the climate alarmists’
fashionable “global warming” narrative.
By cooling the record-breaking
year of 1934, and promoting 1998 as the hottest year in US history, the
scientists who made the adjustments were able suddenly to show 20th
century temperatures shooting up – where before they looked either flat
or declining.
As Goddard notes, the Environmental Protection Agency’s heatwave
record makes a mockery of these adjustments.
It quite clearly shows that
the US heat waves of the 1930s were of an order of magnitude greater
than anything experienced at any other time during the century – far
more severe than those in the 1980s or 1990s which were no worse than
those in the 1950s.
These adjustments, however, are not limited to the US temperature data
sets. Similar fabrications have taken place everywhere from Iceland to Australia.
The fact that supposedly reputable scientists can make these dishonest
adjustments and get away with it is, notes long-time sceptic Christopher Booker, one of the more remarkable anomalies of the great climate change scam.
When I first began examining the global-warming scare, I found nothing
more puzzling than the way officially approved scientists kept on being
shown to have finagled their data, as in that ludicrous “hockey stick”
graph, pretending to prove that the world had suddenly become much
hotter than at any time in 1,000 years.
Any theory needing to rely so
consistently on fudging the evidence, I concluded, must be looked on not
as science at all, but as simply a rather alarming case study in the
aberrations of group psychology.
