This is one of the most definitive smoking guns I have seen of government corruption and collusion in creating a climate crisis that doesn’t exist! The US raw ground temperature data used to support any statement of the climate trends and, therefore, political decisions are no longer credible or trusted. They have been manipulated in what can only be described as an Orwellian manner.
In the UK Climate Research Unit (CRU) ClimateGate incident, much of the raw data behind their temperature record was revealed as ‘missing’. All they had was manipulated data that no one could validate as accurate. Not to worry, the CRU defenders said. They are only 1 of 3 major global temp datasets used to ‘prove’ Global Warming. Anthony Watts of the Watts Up With That? blog explains:
There are three main global temperature datasets. One is at the CRU, Climate Research Unit of the University of East Anglia, where we’ve been trying to get access to the raw numbers. One is at NOAA/GHCN, the Global Historical Climate Network. The final one is at NASA/GISS, the Goddard Institute for Space Studies. The three groups take raw data, and they “homogenize” it to remove things like when a station was moved to a warmer location and there’s a 2C jump in the temperature. The three global temperature records are usually called CRU, GISS, and GHCN. Both GISS and CRU, however, get almost all of their raw data from GHCN. All three produce very similar global historical temperature records from the raw data. (Source)
When Anthony Watts stumbled across issues in the shoddy network of ground temperature stations in the US in 2007, he started an independent review with a site called SurfaceStations.org. The scrutiny and embarrassment to the US governing body (National Climatic Data Center) overseeing this critical network of raw climate data led to admissions of poor quality in the USHCN and the creation of a new network in 2003. Over 90% of temperature stations failed the NRDC’s own standards for siting them away from urban or environmental factors that create a false heat bias.
What now makes the US-component of the supposed ‘raw’ temperature data suspect came with unexplainable changes to ‘raw’ temp data between 2007 and 2009. The Internet was the undoing of this attempt at invisible data manipulation by NASA/GISS/NOAA/GHCN. It was caught by comparing the snapshots of raw data and surveys built out at the SurfaceStations.org site in 2007 with the current online data. While looking at an example of one of the few properly sited ground temperature stations in Orland, CA, that station showed how- amazingly!- the temps showed a decline from it’s start in 1880 to the present:
It was very interesting that the recent decade was NOT the warmest- it was back in the pre-1900’s. But even if you dumped that data segment as possibly corrupted, the next hottest temps in the 20th century were in the 1930’s, particularly 1934 that NASA had to be embarrassed into correcting itself after being audited by private statistican Steven McIntyre– not 1998! While anecdotal, this is in the continental US and a point worth following up on at other temp recording stations. This strongly undermines Gore and company’s predicted climate doom since the warm summer of 1998 was not the peak high of the 20th Century. This (1998 temp) was previously the Global Warming alarmist gold standard proof of man-made influence since they said it was an UNPRECEDENTED warming year and occurred only recently. With 1934 as the peak year and the 1930’s the peak warm decade, the case for human-driven CO2 emissions strongly influencing temps looked doubtful.
The site also had an active link to the current GISS source. Since the graphic from 2007 was smaller, I clicked on the link to see the actual Government tax-dollar financed data in an expanded view, but got this instead!
Not only does this have the warmest data clipped off of it, it changes the ‘raw’ data to re-establish 1998 as the warmest temp and depresses the whole first half by a significant factor. Seems to be that ‘raw’ data is no longer raw and is re-made into something fitting the political climate alarmist template. The raw temps in any of the stations are now suspect and several that were snapshotted in 2007 show this blantant manipulation- always in a conforming Warmist direction.
When will the manipulation by those with political, financial or professional environmental interests stop? Virtually none of our climate data we have now can be trusted. Who has changed what? Where is the objective raw data? We certainly are NOT at a point where we should jump off the green cliff to ‘save’ the planet by going back to a 3rd world standard of living.
